[0252] The embodiments and advantages of the present invention are described in detail below with reference to the accompanying drawings.

[0253] (First Implementation)

[0254] Figure 1 This is a diagram showing the stator of the electro-mechanical energy converter being tested in this experiment.

[0255] Furthermore, unless otherwise specified, in the following description, the electro-mechanical energy converter is illustrated by a rotating electric machine that functions as an electric motor or generator.

[0256] Figure 1 This describes the characteristic configuration of the rotary electric machine of this embodiment, namely the stator core. Furthermore, Figure 1 Although a stator core for an internal rotor type rotary electric machine is shown, this is only one example. The essence of the invention can also be applied to external rotor type rotary electric machines.

[0257] like Figure 1 As shown, the stator core 20 is cylindrical with multiple teeth 2001, 2002, ... protruding from the inner circumferential wall of its base. Figure 1 The stator core 20 is formed by laminating thin sheets of electromagnetic steel. (The text also mentions 192 teeth on the protrusions.)

[0258] Figure 2 This is a diagram illustrating an example of a conductive tube.

[0259] The conductive tube 100 is conductive and allows the flow of a heat transfer medium. An insulating treatment using an insulating varnish or the like is applied to its surface. Furthermore, since the heat transfer medium flows along the inner circumference, an insulating treatment using an insulating varnish or the like can also be applied to this inner circumference surface. Although in Figure 2 This indicates a flat shape as an example of the conductive tube 100, but it can also be cylindrical.

[0260] The conductive tube 100 is disposed in the space (slot) between the teeth of the stator core 20. In addition, the conductive tube 100 is longer than the thickness of the stator core 20, so when disposed in the slot of the stator core 20, it protrudes to both sides of the stator core 20.

[0261] Figure 3 This is a diagram showing an example of a connector.

[0262] As described above, the conductive tube 100 is thicker than the stator core 20, and when positioned in the slot of the stator core 20, it protrudes to both sides of the stator core 20. The connector connects to this protruding portion, enabling specific conductive tubes to conduct electricity to each other. Figure 3 The connector 200 shown is disposed on the outer periphery of the stator core 20 and connects to the conductive tube 100 from the outer periphery. However, this is only one example. It can also be disposed on the inner periphery of the stator core 20 and connect to the conductive tube 100 from the inner periphery.

[0263] Figure 4 This is a view of the stator from the side.

[0264] The conductive tube 100 is disposed in the space (slot) between the teeth of the stator core 20, and the connector 200 is connected to the portions protruding from both sides of the stator core 20. The specific connection points will be described later.

[0265] Figure 5 This is a view of the stator from an oblique angle.

[0266] As described above, connector 200 connects to conductive tubes 100 protruding from both sides of stator core 20. Resin-made heat transfer medium flow members 300 (310, 320) are arranged above and below stator core 20.

[0267] Figure 6 This is a magnified view of the vicinity of the heat medium flow component located above the stator core, viewed from an obliquely upward angle.

[0268] A hole of the same shape as the conductive tube 100 is formed on the bottom surface of the heat medium flow member 310, and the conductive tube 100 is inserted into this hole. The insertion portion of the conductive tube 100 into the hole is in a liquid-tight state, configured to prevent leakage of the heat medium. Furthermore, although... Figure 5 and Figure 6 The cover portion of the heat medium flow member 310 is omitted, and is configured to prevent the heat medium from leaking from the heat medium flow member 310 to the outside.

[0269] Figure 7 This is an exploded view showing an example of a rotating electric machine.

[0270] In addition, Figures 1-6 While the example illustrates 192 teeth protruding from the stator core 20 and 192 conductive tubes arranged in the space between the teeth, its construction is quite complex. Therefore, in the following description, for ease of understanding, a simplified construction will be used as an example. However, these are not merely simple models. They can certainly operate in practice.

[0271] Figure 7 The rotary motor 1 shown has a structure in which 12 teeth are raised on the stator core 20 and 12 conductive tubes are arranged in the spaces (slots) between the teeth. The rotor 50 is a 4-pole type. Figure 7 The rotary motor is a 12N4P type.

[0272] The stator core 20 is formed by laminating thin sheet-like electromagnetic steel plates. In the stator core 20, 12 teeth protrude from the inner peripheral wall of the base. Then, 12 conductive tubes 111, 112, ... are arranged in the spaces (slots) between the teeth. The conductive tubes are longer than the stator core 20, and therefore protrude to both sides of the stator core 20 when arranged in the slots. Connectors 211, 221, ... connect to these protruding portions, allowing specific conductive tubes to conduct electricity to each other. Further details will be provided later.

[0273] Furthermore, heat transfer medium flow members 310 and 320 are arranged on both sides of the stator core 20. Conductive tubes 111, 112, ... are inserted into the holes of these heat transfer medium flow members 310 and 320.

[0274] The heat medium flow member 310 includes a body portion 311 and a cover portion 312. A flow path for heat medium flow is formed in the body portion 311. This flow path is divided into two regions by a pair of partitions 3100. A first heat medium flow pipe 331 for supplying or discharging heat medium is connected to one side region (first heat medium flow region 3101). A second heat medium flow pipe 332 for discharging or supplying heat medium is connected to the other side region (second heat medium flow region 3102). The cover portion 312 is liquid-tightly fixed to the body portion 311 in such a way that the heat medium flowing in the flow path of the body portion 311 will not leak to the outside.

[0275] The heat medium flow member 320 includes a body portion 321 and a cover portion 322. A flow path for heat medium flow is formed in the body portion 321. The cover portion 322 is liquid-tightly fixed to the body portion 321 in such a way that the heat medium flowing in the flow path of the body portion 321 will not leak to the outside.

[0276] U-phase line 11 is connected to one of the 12 U-phase conductive tubes. V-phase line 12 is connected to one of the 12 V-phase conductive tubes. W-phase line 13 is connected to one of the 12 W-phase conductive tubes.

[0277] Figure 8 yes Figure 7 The assembly diagram of the rotary electric motor shown is as follows. Figure 8 (A) is a view taken from a left-hand oblique angle. Figure 8 (B) is a view from a right-angled perspective.

[0278] If you watch Figure 8 (A) and Figure 8 (B) It can be seen that heat medium flow components 310 and 320 are arranged on both sides of the stator core 20. Furthermore, if viewed... Figure 8 (B) It can be seen that a first heat medium flow pipe 331 and a second heat medium flow pipe 332 are provided in the heat medium flow component 310. Furthermore, it can be seen that the U phase line 11, V phase line 12 and W phase line 13 protrude.

[0279] Figure 9 It is Figure 7 The diagram shown is an unfolded version of the rotary electric motor model.

[0280] Multiple teeth protrude from the inner peripheral wall of the base of the stator core 20. Figure 9 In the middle, starting from the left, the teeth are: first tooth 2001, second tooth 2002, third tooth 2003, fourth tooth 2004, fifth tooth 2005, sixth tooth 2006, seventh tooth 2007, eighth tooth 2008, ninth tooth 2009, tenth tooth 2010, eleventh tooth 2011, and twelfth tooth 2012.

[0281] Conductive tubes are arranged in the spaces (slots) between the teeth. A U-phase first conductive tube 111 is arranged in the space (slot) between the first tooth 2001 and the second tooth 2002. A V-phase fourth conductive tube 124 is arranged in the space (slot) between the second tooth 2002 and the third tooth 2003. A W-phase third conductive tube 133 is arranged in the space (slot) between the third tooth 2003 and the fourth tooth 2004. A U-phase second conductive tube 112 is arranged in the space (slot) between the fourth tooth 2004 and the fifth tooth 2005. A V-phase first conductive tube 121 is arranged in the space (slot) between the fifth tooth 2005 and the sixth tooth 2006. A W-phase fourth conductive tube 134 is arranged in the space (slot) between the sixth tooth 2006 and the seventh tooth 2007. A U-phase third conductive tube 113 is arranged in the space (slot) between the seventh tooth 2007 and the eighth tooth 2008. A V-phase second conductive tube 122 is disposed in the space (slot) between the eighth tooth section 2008 and the ninth tooth section 2009. A W-phase first conductive tube 131 is disposed in the space (slot) between the ninth tooth section 2009 and the tenth tooth section 2010. A U-phase fourth conductive tube 114 is disposed in the space (slot) between the tenth tooth section 2010 and the eleventh tooth section 2011. A V-phase third conductive tube 123 is disposed in the space (slot) between the eleventh tooth section 2011 and the twelfth tooth section 2012. A W-phase second conductive tube 132 is disposed in the space (slot) between the twelfth tooth section 2012 and the first tooth section 2001.

[0282] A heat medium flow member 310 is disposed above (on one end) the stator core 20. The interior of the heat medium flow member 310 is divided into two regions by a pair of partitions 3100. A first heat medium flow pipe 331 for supplying or discharging heat medium is connected to the region on one side (first heat medium flow region 3101). A second heat medium flow pipe 332 for discharging or supplying heat medium is connected to the region on the other side (second heat medium flow region 3102).

[0283] Twelve holes are formed on the bottom surface of the heat medium flow member 310 on one side. Six holes are formed in the first heat medium flow region 3101. The remaining six holes are formed in the second heat medium flow region 3102.

[0284] Insert one end of the U-phase first conductive tube 111, the V-phase fourth conductive tube 124, the W-phase third conductive tube 133, the U-phase second conductive tube 112, the V-phase first conductive tube 121, and the W-phase fourth conductive tube 134 into the hole formed in the first heat medium flow region 3101.

[0285] Insert one end of the U-phase third conductive tube 113, the V-phase second conductive tube 122, the W-phase first conductive tube 131, the U-phase fourth conductive tube 114, the V-phase third conductive tube 123, and the W-phase second conductive tube 132 into the hole formed in the second heat medium flow region 3102.

[0286] A heat transfer medium flow member 320 is disposed below the stator core 20 (on the other end side). Twelve holes are formed on the bottom surface of the heat transfer medium flow member 320. The other ends of the U-phase first conductive tube 111, V-phase fourth conductive tube 124, W-phase third conductive tube 133, U-phase second conductive tube 112, V-phase first conductive tube 121, W-phase fourth conductive tube 134, U-phase third conductive tube 113, V-phase second conductive tube 122, W-phase first conductive tube 131, U-phase fourth conductive tube 114, V-phase third conductive tube 123, and W-phase second conductive tube 132 are inserted into these holes.

[0287] A U-phase line 11 is connected to one end of the first U-phase conductive tube 111. The U-phase line 11 is a solid wire. A first connector 2121 is connected to the other end of the first U-phase conductive tube 111 and the other end of the second U-phase conductive tube 112, thereby making the first U-phase conductive tube 111 and the second U-phase conductive tube 112 conductive.

[0288] A U-phase one-end connector 211 is connected to one end of the U-phase second conductive tube 112 and one end of the U-phase third conductive tube 113, thereby enabling the U-phase second conductive tube 112 and the U-phase third conductive tube 113 to conduct.

[0289] A second connector 2122 is connected to the other end of the U-phase third conductive tube 113 and the other end of the U-phase fourth conductive tube 114, thereby making the U-phase third conductive tube 113 and the U-phase fourth conductive tube 114 conductive.

[0290] A V-phase line 12 is connected to one end of the first V-phase conductive tube 121. The V-phase line 12 is a solid wire. A first connector 2221 is connected to the other end of the first V-phase conductive tube 121 and the other end of the second V-phase conductive tube 122, thereby making the first V-phase conductive tube 121 and the second V-phase conductive tube 122 conductive.

[0291] A V-phase one-end connector 221 is connected to one end of the V-phase second conductive tube 122 and one end of the V-phase third conductive tube 123, thereby enabling the V-phase second conductive tube 122 and the V-phase third conductive tube 123 to conduct.

[0292] A second connector 2222 is connected to the other end of the V-phase third conductive tube 123 and the other end of the V-phase fourth conductive tube 124, thereby making the V-phase third conductive tube 123 and the V-phase fourth conductive tube 124 conductive.

[0293] A W-phase wire 13 is connected to one end of the first W-phase conductive tube 131. The W-phase wire 13 is a solid conductor. A first connector 2321 is connected to the other end of the first W-phase conductive tube 131 and the other end of the second W-phase conductive tube 132, thereby making the first W-phase conductive tube 131 and the second W-phase conductive tube 132 conductive.

[0294] A W-phase one-end connector 231 is connected to one end of the W-phase second conductive tube 132 and one end of the W-phase third conductive tube 133, thereby enabling the W-phase second conductive tube 132 and the W-phase third conductive tube 133 to conduct.

[0295] A second connector 2322 is connected to the other end of the W phase third conductive tube 133 and the other end of the W phase fourth conductive tube 134, thereby making the W phase third conductive tube 133 and the W phase fourth conductive tube 134 conductive.

[0296] Then, a neutral line connector 240 is connected to one end of the U-phase fourth conductive tube 114, one end of the V-phase fourth conductive tube 124, and one end of the W-phase fourth conductive tube 134, so that the U-phase fourth conductive tube 114, the V-phase fourth conductive tube 124, and the W-phase fourth conductive tube 134 are connected.

[0297] Figure 10 This is an explanation Figure 9 The diagram shown illustrates the flow of the heat medium in the unfolded model. Furthermore, the arrows indicate the direction of heat medium flow.

[0298] The heat medium supplied from the first heat medium flow pipe 331 originates from the first heat medium flow area 3101 of the heat medium flow member 310 on one side, flows through any one of the following: the first conductive pipe 111 of the U phase, the fourth conductive pipe 124 of the V phase, the third conductive pipe 133 of the W phase, the second conductive pipe 112 of the U phase, the first conductive pipe 121 of the V phase, and the fourth conductive pipe 134 of the W phase, and reaches the heat medium flow member 320 on the other side. Then, it flows through any one of the following: the third conductive pipe 113 of the U phase, the second conductive pipe 122 of the V phase, the first conductive pipe 131 of the W phase, the fourth conductive pipe 114 of the U phase, the third conductive pipe 123 of the V phase, and the second conductive pipe 132 of the W phase, and reaches the second heat medium flow area 3102 of the heat medium flow member 310 on one side, and is discharged from the second heat medium flow pipe 332. Furthermore, although the heat medium is described in this embodiment as being supplied from the first heat medium flow pipe 331 and discharged from the second heat medium flow pipe 332, it may also be supplied from the second heat medium flow pipe 332 and discharged from the first heat medium flow pipe 331.

[0299] Next, the flow of electric current will be explained.

[0300] Figure 11 This means that in Figure 9 The diagram shown illustrates the flow of current from the U-phase line to the V-phase line. Furthermore, the arrows indicate the direction of current flow.

[0301] First, let's explain the case where current flows from phase U 11 to phase V 12.

[0302] The current flowing into phase U11 flows as follows: phase U11 → phase U1 ...

[0303] Figure 12 This means that in Figure 9 The diagram shown illustrates the flow of current from the V-phase line to the W-phase line. Furthermore, the arrows indicate the direction of current flow.

[0304] Next, we will explain the case where current flows from the V-phase line 12 to the W-phase line 13.

[0305] The current flowing into phase V line 12 flows as follows: phase V line 12 → phase V first conductive tube 121 → phase V other end first connector 2221 → phase V second conductive tube 122 → phase V one end connector 221 → phase V third conductive tube 123 → phase V other end second connector 2222 → phase V fourth conductive tube 124 → neutral line connector 240 → phase W fourth conductive tube 134 → phase W other end second connector 2322 → phase W third conductive tube 133 → phase W one end connector 231 → phase W second conductive tube 132 → phase W other end first connector 2321 → phase W first conductive tube 131 → phase W line 13.

[0306] Figure 13 This means that in Figure 9 The diagram shown illustrates the flow of current from phase W to phase U in the unfolded model. Furthermore, the arrows indicate the direction of current flow.

[0307] Next, we will explain the case where current flows from phase W 13 to phase U 11.

[0308] The current flowing into phase W line 13 flows as follows: phase W line 13 → phase W first conductive tube 131 → phase W other end first connector 2321 → phase W second conductive tube 132 → phase W one end connector 231 → phase W third conductive tube 133 → phase W other end second connector 2322 → phase W fourth conductive tube 134 → neutral line connector 240 → phase U fourth conductive tube 114 → phase U other end second connector 2122 → phase U third conductive tube 113 → phase U one end connector 211 → phase U second conductive tube 112 → phase U other end first connector 2121 → phase U first conductive tube 111 → phase U line 11.

[0309] According to the embodiment described above, the cooling performance is excellent because the heat medium flows inside each conductive tube.

[0310] Furthermore, by arranging each conductive tube in the space (slot) between the teeth of the stator core 20, inserting one end of each conductive tube into a hole formed in the heat medium flow member 310 on one side, and inserting the other end into a hole formed in the heat medium flow member 320 on the other side, these conductive tubes are held in place. Because this is done in this way, it is not necessary to wind the wires around the teeth as in a conventional rotary motor, resulting in excellent productivity.

[0311] Furthermore, the heat medium is supplied from the first heat medium flow pipe 331 of the heat medium flow member 310 located on one side. It flows from the first heat medium flow area 3101, through the groove of any conductive pipe, to the heat medium flow member 320 on the other side, through the grooves of other conductive pipes, to the second heat medium flow area 3102 of the heat medium flow member 310 on one side, and is then discharged from the second heat medium flow pipe 332. Thus, because both the heat medium supply point and discharge point are located on one side of the heat medium flow member 310, the assembly of the rotary motor of this embodiment when installed in the equipment is excellent.

[0312] (Second Implementation)

[0313] Figure 14 This is an exploded view showing the second embodiment of the rotary electric machine.

[0314] Furthermore, in the following description, parts that perform the same function as described above will be marked with the same symbols and repeated descriptions will be omitted as appropriate.

[0315] In this second embodiment, the shapes of the heat medium flow member 310 on one side and the heat medium flow member 320 on the other side are different from those in the first embodiment.

[0316] That is, in the heat medium flow member 310 of the first embodiment, the interior is divided into two regions by a pair of partitions 3100, while in the heat medium flow member 310 of the second embodiment, there are no partitions. Furthermore, in the heat medium flow member 310 of the second embodiment, although a first heat medium flow pipe 331 is connected to the heat medium flow, there is no second heat medium flow pipe 332 connected to the heat medium flow.

[0317] Then, a second heat medium flow pipe 332 is connected to the heat medium flow member 320 on the other side.

[0318] Figure 15 yes Figure 14 The assembly diagram of the rotary electric motor shown is as follows. Figure 15 (A) is a view taken from a left-hand oblique angle. Figure 15 (B) is a view from a right-angled perspective.

[0319] If you watch Figure 15 (A) It can be seen that a second heat medium flow pipe 332 is provided on the heat medium flow member 320 on the other side. Furthermore, if viewed... Figure 15 (B) It can be seen that a first heat medium flow pipe 331 is provided on one side of the heat medium flow component 310. Figure 16 It is Figure 14 The diagram shown is a modeled unfolded view of the rotating electric motor. Furthermore, the arrows indicate the flow direction of the heat medium.

[0320] Conductive tubes are arranged in the spaces (slots) between the teeth of the stator core 20. The arrangement of these teeth and conductive tubes, the connection configuration of the connectors, etc., are the same as in the first embodiment, so the description is omitted.

[0321] A heat medium flow member 310 is disposed above (on one end) the stator core 20. A first heat medium flow pipe 331 for supplying or discharging heat medium is connected to the heat medium flow member 310 on one side. A second heat medium flow pipe 332 for discharging or supplying heat medium is connected to the heat medium flow member 320 on the other side.

[0322] The heat medium supplied from the first heat medium flow pipe 331 originates from the heat medium flow member 310 on one side, flows through any one of the following: U-phase first conductive pipe 111, V-phase fourth conductive pipe 124, W-phase third conductive pipe 133, U-phase second conductive pipe 112, V-phase first conductive pipe 121, W-phase fourth conductive pipe 134, U-phase third conductive pipe 113, V-phase second conductive pipe 122, W-phase first conductive pipe 131, U-phase fourth conductive pipe 114, V-phase third conductive pipe 123, and W-phase second conductive pipe 132, and reaches the heat medium flow member 320 on the other side, where it is discharged from the second heat medium flow pipe 332. Furthermore, although this embodiment describes the heat medium as being supplied from the first heat medium flow pipe 331 and discharged from the second heat medium flow pipe 332, it could also be supplied from the second heat medium flow pipe 332 and discharged from the first heat medium flow pipe 331.

[0323] As explained above, according to this second embodiment, the cooling performance is excellent because the heat medium flows inside each conductive tube. In particular, in this second embodiment, the heat medium is supplied from the first heat medium flow pipe 331 of the heat medium flow member 310 located on one side, flows from the first heat medium flow area 3101 through the groove of any conductive tube, reaches the heat medium flow member 320 on the other side, and is discharged from the second heat medium flow pipe 332. Thus, because the flow distance of the heat medium is short, the cooling performance is even better than in the first embodiment.

[0324] Furthermore, because all the heat transfer media are directed in one direction (in...) Figure 16 The flow is from top to bottom, so the flow resistance of the hot medium is small, which can reduce the output of the hot medium supply equipment such as pumps.

[0325] (Third Implementation)

[0326] Figure 17 This is an exploded view showing the third embodiment of the rotary electric machine.

[0327] In the first and second embodiments described above, a heat transfer medium flow member 310 on one side and a heat transfer medium flow member 320 on the other side are arranged on both sides of the stator core 20. In contrast, in this third embodiment, a heat transfer medium flow member 310 is arranged only on one side of the stator core 20, and no heat transfer medium flow member is arranged on the other side. The other ends of each conductive tube are connected by a connecting tube.

[0328] The heat medium flow member 310 includes a first body portion 3111, a second body portion 3112, and a cover portion 312. Flow paths for heat medium flow are formed in the first body portion 3111 and the second body portion 3112. A first heat medium flow pipe 331 for supplying or discharging heat medium is connected to the first body portion 3111. A second heat medium flow pipe 332 for discharging or supplying heat medium is connected to the second body portion 3112. The second body portion 3112 is liquid-tightly fixed to the first body portion 3111 in such a way that the heat medium flowing in the flow path of the first body portion 3111 will not leak to the outside. The cover portion 312 is liquid-tightly fixed to the second body portion 3112 in such a way that the heat medium flowing in the flow path of the second body portion 3112 will not leak to the outside.

[0329] Figure 18 yes Figure 17 The assembly diagram of the rotary electric motor shown is as follows. Figure 18 (A) is a view taken from a left-hand oblique angle. Figure 18 (B) is a view from a right-angled perspective.

[0330] If you watch Figure 18 (A) It can be seen that the other end of each conductive tube is connected through connecting tubes 2131, 2131, ... If you look at Figure 18 (B) It can be seen that the heat medium flow component 310 is provided with a first heat medium flow pipe 331 and a second heat medium flow pipe 332. Details will be described later.

[0331] Figure 19 It is Figure 17 The diagram shown is an unfolded version of the rotary electric motor model.

[0332] Conductive tubes are arranged in the spaces (slots) between the teeth of the stator core 20. The arrangement order of these teeth and conductive tubes is the same as in the first embodiment, so the description is omitted.

[0333] A heat medium flow member 310 is disposed above (on one end) the stator core 20. The heat medium flow member 310 includes a first body portion 3111, a second body portion 3112, and a cover portion 312. The second body portion 3112 is liquid-tightly fixed to the first body portion 3111 in such a way that the heat medium flowing in the flow path of the first body portion 3111 will not leak to the outside. The cover portion 312 is liquid-tightly fixed to the second body portion 3112 in such a way that the heat medium flowing in the flow path of the second body portion 3112 will not leak to the outside. With this structure, the flow path of the heat medium formed inside the heat medium flow member 310 is divided into upper and lower sections. A first heat medium flow pipe 331 for supplying or discharging heat medium is connected to one side of the first body portion 3111 (first heat medium flow area 3101). A second heat medium flow pipe 332 for discharging or supplying heat medium is connected to the other side of the second body portion 3112 (second heat medium flow area 3102).

[0334] Twelve holes are formed on the bottom surface of the first body part 3111. Six holes are formed on the second body part 3112.

[0337] A U-phase line 11 is connected to one end of the first U-phase conductive tube 111. The U-phase line 11 is a solid conductor. A first connecting tube 2131 is connected to the other end of the first U-phase conductive tube 111 and the other end of the second U-phase conductive tube 112. Due to the above configuration, the first U-phase conductive tube 111 and the second U-phase conductive tube 112 are conductive and allow the flow of heat transfer medium.

[0338] A U-phase connector 211 is connected to one end of the second U-phase conductive tube 112 and one end of the third U-phase conductive tube 113, thereby enabling the second U-phase conductive tube 112 and the third U-phase conductive tube 113 to conduct.

[0339] A second connecting pipe 2132 on the other end side of the U-phase is connected to the other end of the third conductive tube 113 and the other end of the fourth conductive tube 114 of the U-phase. Due to the above configuration, the third conductive tube 113 and the fourth conductive tube 114 of the U-phase are capable of conducting electricity and allowing the heat medium to flow.

[0340] A V-phase line 12 is connected to one end of the first V-phase conductive tube 121. The V-phase line 12 is a solid conductor. A first connecting tube 2231 is connected to the other end of the first V-phase conductive tube 121 and the other end of the second V-phase conductive tube 122. Due to the above configuration, the first V-phase conductive tube 121 and the second V-phase conductive tube 122 are conductive and allow the flow of heat transfer medium.

[0341] A V-phase connector 221 is connected to one end of the second V-phase conductive tube 122 and one end of the third V-phase conductive tube 123, thereby enabling the second V-phase conductive tube 122 and the third V-phase conductive tube 123 to conduct.

[0342] A second connecting pipe 2232 is connected to the other end of the V-phase third conductive tube 123 and the other end of the V-phase fourth conductive tube 124. Due to the above configuration, the V-phase third conductive tube 123 and the V-phase fourth conductive tube 124 are capable of conducting electricity and allowing the heat medium to flow.

[0343] A W-phase line 13 is connected to one end of the first W-phase conductive tube 131. The W-phase line 13 is a solid conductor. A first connecting tube 2331 is connected to the other end of the first W-phase conductive tube 131 and the other end of the second W-phase conductive tube 132. Due to the above configuration, the first W-phase conductive tube 131 and the second W-phase conductive tube 132 are conductive and allow the flow of heat transfer medium.

[0344] A W-phase connector 231 is connected to one end of the W-phase second conductive tube 132 and one end of the W-phase third conductive tube 133, thereby enabling the W-phase second conductive tube 132 and the W-phase third conductive tube 133 to conduct.

[0345] A second connecting pipe 2332 is connected to the other end of the third conductive tube 133 and the fourth conductive tube 134 of the W phase. Due to the above configuration, the third conductive tube 133 and the fourth conductive tube 134 of the W phase are capable of conducting electricity and allowing the heat medium to flow.

[0346] Then, a neutral line connector 240 is connected to one end of the U-phase fourth conductive tube 114, one end of the V-phase fourth conductive tube 124, and one end of the W-phase fourth conductive tube 134, so that the U-phase fourth conductive tube 114, the V-phase fourth conductive tube 124, and the W-phase fourth conductive tube 134 are connected.

[0347] Figure 20 This is an explanation Figure 19The diagram shown is a representation of the flow of the thermal medium in the unfolded model.

[0348] The heat medium supplied from the first heat medium flow pipe 331 flows from the first heat medium flow area 3101 in the following direction: U phase first conductive pipe 111 → U phase other end side first connecting pipe 2131 → U phase second conductive pipe 112, and reaches the second heat medium flow area 3102.

[0349] The second flow direction is as follows: U-phase third conductive pipe 113 → U-phase other end side second connecting pipe 2132 → U-phase fourth conductive pipe 114, and reaches the second heat medium flow area 3102.

[0350] The third flow direction is as follows: V phase first conductive tube 121 → V phase other end side first connecting tube 2231 → V phase second conductive tube 122, and reaches the second heat medium flow area 3102.

[0351] The fourth flow direction is as follows: V phase third conductive pipe 123 → V phase other end side second connecting pipe 2232 → V phase fourth conductive pipe 124, and reaches the second heat medium flow area 3102.

[0352] The fifth flow direction is as follows: W phase first conductive pipe 131 → W phase other end side first connecting pipe 2331 → W phase second conductive pipe 132, and reaches the second heat medium flow area 3102.

[0353] The sixth flow direction is as follows: W phase third conductive pipe 133 → W phase other end side second connecting pipe 2332 → W phase fourth conductive pipe 134, and reaches the second heat medium flow area 3102.

[0354] The heat medium reaches the second heat medium flow area 3102 as described above and is discharged from the second heat medium flow pipe 332. Furthermore, although this embodiment describes the heat medium as being supplied from the first heat medium flow pipe 331 and discharged from the second heat medium flow pipe 332, it could also be supplied from the second heat medium flow pipe 332 and discharged from the first heat medium flow pipe 331.

[0355] Next, the flow of electric current will be explained.

[0356] Figure 21 This means that in Figure 19 The diagram shown illustrates the flow of current from the U-phase line to the V-phase line. Furthermore, the arrows indicate the direction of current flow.

[0357] First, let's explain the case where current flows from phase U 11 to phase V 12.

[0358] The current flowing into the U-phase line 11 flows as follows: U-phase line 11 → U-phase first conductive tube 111 → U-phase other end first connecting tube 2131 → U-phase second conductive tube 112 → U-phase connector 211 → U-phase third conductive tube 113 → U-phase other end second connecting tube 2132 → U-phase fourth conductive tube 114 → neutral line connector 240 → V-phase fourth conductive tube 124 → V-phase other end second connecting tube 2232 → V-phase third conductive tube 123 → V-phase connector 221 → V-phase second conductive tube 122 → V-phase other end first connecting tube 2231 → V-phase first conductive tube 121 → V-phase line 12.

[0359] Figure 22 This means that in Figure 19 The diagram shown illustrates the flow of current from the V-phase line to the W-phase line. Furthermore, the arrows indicate the direction of current flow.

[0360] Next, we will explain the case where current flows from the V-phase line 12 to the W-phase line 13.

[0361] The current flowing into phase V line 12 flows as follows: phase V line 12 → phase V first conductive tube 121 → phase V other end first connecting tube 2231 → phase V second conductive tube 122 → phase V connector 221 → phase V third conductive tube 123 → phase V other end second connecting tube 2232 → phase V fourth conductive tube 124 → neutral line connector 240 → phase W fourth conductive tube 134 → phase W other end second connecting tube 2332 → phase W third conductive tube 133 → phase W connector 231 → phase W second conductive tube 132 → phase W other end first connecting tube 2331 → phase W first conductive tube 131 → phase W line 13.

[0362] Figure 23 This means that in Figure 19 The diagram shown illustrates the flow of current from phase W to phase U in the unfolded model. Furthermore, the arrows indicate the direction of current flow.

[0363] Next, we will explain the case where current flows from phase W 13 to phase U 11.

[0364] The current flowing into phase W line 13 flows as follows: phase W line 13 → phase W first conductive tube 131 → phase W other end first connecting tube 2331 → phase W second conductive tube 132 → phase W connector 231 → phase W third conductive tube 133 → phase W other end second connecting tube 2332 → phase W fourth conductive tube 134 → neutral line connector 240 → phase U fourth conductive tube 114 → phase U other end second connecting tube 2132 → phase U third conductive tube 113 → phase U connector 211 → phase U second conductive tube 112 → phase U other end first connecting tube 2131 → phase U first conductive tube 111 → phase U line 11.

[0365] As explained above, according to this third embodiment, the cooling performance is excellent because the heat medium flows inside each conductive tube.

[0366] Furthermore, in the first and second embodiments, a heat transfer medium flow member 310 on one side and a heat transfer medium flow member 320 on the other side are arranged on both sides of the stator core 20. In contrast, in this third embodiment, a heat transfer medium flow member is arranged only on one side of the stator core 20, and no heat transfer medium flow member is arranged on the other side. Due to this configuration, the dimensions are compact.

[0367] Furthermore, since both the supply and discharge points of the heat medium are located in the heat medium flow component, the assembly of the rotary motor of this embodiment when installed in the equipment is excellent.

[0368] Furthermore, in the first embodiment, the heat medium supplied from the first heat medium flow pipe 331 originates from the first heat medium flow area 3101 of the heat medium flow member 310 on one side, passes through any conductive pipe, reaches the heat medium flow member 320 on the other side, and then passes through any conductive pipe to the second heat medium flow area 3102 of the heat medium flow member 310 on one side. At this time, in the heat medium flow member 320 on the other side, the flow of the heat medium may interfere with each other and cannot flow smoothly.

[0369] In contrast, in this third embodiment, since the heat medium flows in one direction within the connecting pipe, the flow resistance of the heat medium is small, which can reduce the output of heat medium supply equipment such as pumps.

[0370] (Fourth Implementation)

[0371] Figure 24 This is an exploded view showing the fourth embodiment of the rotary electric machine.

[0372] In the above embodiments, each connector is connected to a conductive tube protruding from the stator core 20. Then, the end of the conductive tube is inserted into a hole formed on the bottom surface of the heat transfer medium member. That is, each connector is positioned between the stator core 20 and the heat transfer medium member.

[0373] In contrast, in this fourth embodiment, each connector is disposed inside the heat medium flow member.

[0374] That is, the heat medium flow member 310 includes a cover plate 311 and a base plate 312. The cover plate 311 is made of metal (e.g., aluminum). The base plate 312 is made of resin, for example, and has insulating properties. Twelve holes are formed in the base plate 312. A pair of partitions 3100 are also formed. The ends of conductive tubes are inserted into the holes of the base plate 312, and each connector is connected to the conductive tube protruding from the base plate 312. The cover plate 311 is then fixedly mounted on the base plate 312.

[0375] The heat transfer medium flow member 320 includes a cover plate 321 and a base plate 322. The cover plate 321 is made of metal (e.g., aluminum). The base plate 322 is made of resin, for example, and is insulating. Twelve holes are formed in the base plate 322. The ends of conductive tubes are inserted into the holes in the base plate 322, and connectors are connected to the conductive tubes protruding from the base plate 322. The cover plate 321 is then fixedly mounted on the base plate 322.

[0376] Figure 25 yes Figure 24 The assembly diagram of the rotary electric motor shown is as follows. Figure 25 (A) is a view taken from a left-hand oblique angle. Figure 25 (B) is a view from a right-angled perspective.

[0377] If you watch Figure 25 (A) and Figure 25 (B) It can be seen that heat medium flow components are arranged on both sides of the stator core 20, and the connectors are not visible. Furthermore, if we look at 25(B), it can be seen that the heat medium flow components are provided with a first heat medium flow pipe 331 and a second heat medium flow pipe 332.

[0378] Figure 26 It is Figure 24 The diagram shown is a modeled unfolded view of the rotating electric motor. Furthermore, the arrows indicate the flow direction of the heat medium.

[0379] A conductive tube is disposed in the space (slot) between the teeth of the stator core 20. One end of the conductive tube is inserted into a hole in the base plate 312 of the heat medium flow member 310 formed on one side. Then, each connector is connected to the conductive tube protruding from the base plate 312. Then, a cover plate 311 is fixedly attached to the base plate 312. And, the other end of the conductive tube is inserted into a hole in the base plate 322 of the heat medium flow member 320 formed on the other side. Then, each connector is connected to the conductive tube protruding from the base plate 322. Then, a cover plate 321 is fixedly attached to the base plate 322.

[0380] Furthermore, the arrangement order of these teeth and conductive tubes is the same as in the first embodiment, so the description is omitted.

[0381] As indicated by the arrows, the heat medium supplied from the first heat medium flow pipe 331 flows into the first heat medium flow area 3101 of the heat medium flow member 310 on one side. At this time, the heat medium cools the connectors present in the first heat medium flow area 3101. Then, it flows through any one of the U-phase first conductive pipe 111, V-phase fourth conductive pipe 124, W-phase third conductive pipe 133, U-phase second conductive pipe 112, V-phase first conductive pipe 121, and W-phase fourth conductive pipe 134, reaching the heat medium flow member 320 on the other side. At this time, the heat medium cools the connectors present in the heat medium flow member 320 on the other side. Then, it flows through any one of the U-phase third conductive pipe 113, V-phase second conductive pipe 122, W-phase first conductive pipe 131, U-phase fourth conductive pipe 114, V-phase third conductive pipe 123, and W-phase second conductive pipe 132, reaching the second heat medium flow area 3102 of the heat medium flow member 310 on one side. At this time, the heat medium cools the connectors present in the second heat medium flow area 3102. Then, it is discharged from the second heat medium flow pipe 332. Furthermore, although the heat medium is described in this embodiment as being supplied from the first heat medium flow pipe 331 and discharged from the second heat medium flow pipe 332, it may also be in the form of being supplied from the second heat medium flow pipe 332 and discharged from the first heat medium flow pipe 331.

[0382] Regarding the current, it is basically the same as in the first embodiment, so the description is omitted here.

[0383] According to the fourth embodiment described above, since each connector is disposed inside the heat medium flow member and is cooled by the heat medium flowing through the heat medium flow member, the cooling performance is excellent.

[0384] Furthermore, since each connector is located inside the heat medium flow component and not exposed to the outside, it can prevent foreign objects from entering between the connectors, thus providing excellent maintainability.

[0385] (Fifth implementation method)

[0386] Figure 27 This is an unfolded diagram of the rotary electric motor according to the fifth embodiment. The rotary electric motor of this fifth embodiment differs from the rotary electric motor of the first embodiment in that the connection of the conductive tube via the connector is different. The arrangement order of the teeth and conductive tube is the same as in the first embodiment, therefore, description is omitted. Furthermore, the structure of the heat medium flow member and the flow mode of the heat medium are also the same as in the first embodiment, therefore, description is omitted.

[0387] A U-phase line 11 is connected to one end of the first U-phase conductive tube 111. Furthermore, a U-phase one-end connector 211 is connected to one end of the first U-phase conductive tube 111 and one end of the third U-phase conductive tube 113, thereby enabling the first U-phase conductive tube 111 and the third U-phase conductive tube 113 to conduct.

[0388] A first connector 2121 is connected to the other end of the U-phase first conductive tube 111 and the other end of the U-phase second conductive tube 112, thereby making the U-phase first conductive tube 111 and the U-phase second conductive tube 112 conductive.

[0389] A second connector 2122 is connected to the other end of the U-phase third conductive tube 113 and the other end of the U-phase fourth conductive tube 114, thereby making the U-phase third conductive tube 113 and the U-phase fourth conductive tube 114 conductive.

[0390] A V-phase line 12 is connected to one end of the first V-phase conductive tube 121. Furthermore, a V-phase one-end connector 221 is connected to one end of the first V-phase conductive tube 121 and one end of the third V-phase conductive tube 123, thereby enabling the first V-phase conductive tube 121 and the third V-phase conductive tube 123 to conduct.

[0391] A first connector 2221 is connected to the other end of the V-phase first conductive tube 121 and the other end of the V-phase second conductive tube 122, thereby making the V-phase first conductive tube 121 and the V-phase second conductive tube 122 conductive.

[0392] A second connector 2222 is connected to the other end of the V-phase third conductive tube 123 and the other end of the V-phase fourth conductive tube 124, thereby making the V-phase third conductive tube 123 and the V-phase fourth conductive tube 124 conductive.

[0393] A W-phase line 13 is connected to one end of the first W-phase conductive tube 131. Furthermore, a W-phase one-end connector 231 is connected to one end of the first W-phase conductive tube 131 and one end of the third W-phase conductive tube 133, thereby enabling the first W-phase conductive tube 131 and the third W-phase conductive tube 133 to conduct.

[0394] A first connector 2321 is connected to the other end of the W-phase first conductive tube 131 and the other end of the W-phase second conductive tube 132, thereby making the W-phase first conductive tube 131 and the W-phase second conductive tube 132 conductive.

[0395] A second connector 2322 is connected to the other end of the W phase third conductive tube 133 and the other end of the W phase fourth conductive tube 134, thereby making the W phase third conductive tube 133 and the W phase fourth conductive tube 134 conductive.

[0396] Then, a neutral line connector 240 is connected to one end of the U-phase second conductive tube 112, one end of the U-phase fourth conductive tube 114, one end of the V-phase second conductive tube 122, one end of the V-phase fourth conductive tube 124, one end of the W-phase second conductive tube 132, and one end of the W-phase fourth conductive tube 134, thereby making the U-phase second conductive tube 112, U-phase fourth conductive tube 114, V-phase second conductive tube 122, V-phase fourth conductive tube 124, W-phase second conductive tube 132, and W-phase fourth conductive tube 134 conductive.

[0397] Next, the flow of current from the U-phase line to the V-phase line will be explained. Furthermore, arrows indicate the direction of current flow.

[0398] The current flowing into phase U 11 splits into two paths. In the first embodiment, the current flows from phase U to phase V without splitting, which is a series connection type. In contrast, in this fifth embodiment, the current splits and then rejoins, which is a parallel connection type.

[0399] One of the flows after the divergence is as follows: U-phase one-end connector 211 → U-phase third conductive tube 113 → U-phase other-end second connector 2122 → U-phase fourth conductive tube 114 → neutral line connector 240 → V-phase second conductive tube 122 → V-phase other-end first connector 2221 → V-phase first conductive tube 121 → V-phase line 12.

[0400] Another flow is as follows: U-phase first conductive tube 111 → U-phase other end first connector 2121 → U-phase second conductive tube 112 → neutral line connector 240; then it branches into two paths.

[0401] Then, one of the flows is as follows: V-phase second conductive tube 122 → V-phase other end side first connector 2221 → V-phase first conductive tube 121 → V-phase line 12.

[0402] The other path is as follows: V-phase fourth conductive tube 124 → V-phase other end side second connector 2222 → V-phase third conductive tube 123 → V-phase one end side connector 221 → V-phase line 12.

[0403] Figure 28 This means that in Figure 27 The diagram shown illustrates the flow of current from the V-phase line to the W-phase line. Furthermore, the arrows indicate the direction of current flow.

[0404] Next, we will explain the case where current flows from the V-phase line 12 to the W-phase line 13.

[0405] The current flowing into phase V line 12 splits into two paths.

[0406] One of the flows is as follows: V-phase one-end connector 221 → V-phase third conductive tube 123 → V-phase other-end second connector 2222 → V-phase fourth conductive tube 124 → neutral line connector 240 → W-phase fourth conductive tube 134 → W-phase other-end second connector 2322 → W-phase third conductive tube 133 → W-phase one-end connector 231 → W-phase line 13.

[0407] Another flow is as follows: V-phase first conductive tube 121 → V-phase other end first connector 2221 → V-phase second conductive tube 122 → neutral line connector 240; then it branches into two paths.

[0408] Then, one of the flows is as follows: W phase second conductive tube 132 → W phase other end side first connector 2321 → W phase first conductive tube 131 → W phase line 13.

[0409] The other path is as follows: W phase fourth conductive tube 134 → W phase other end side second connector 2322 → W phase third conductive tube 133 → W phase one end side connector 231 → W phase line 13.

[0410] Figure 29 This means that in Figure 27 The diagram shown illustrates the flow of current from phase W to phase U in the unfolded model. Furthermore, the arrows indicate the direction of current flow.

[0411] Next, we will explain the case where current flows from phase W 13 to phase U 11.

[0412] The current flowing into phase line 13 from phase W splits into two paths.

[0413] One of the flows is as follows: W phase one end connector 231 → W phase third conductive tube 133 → W phase other end second connector 2322 → W phase fourth conductive tube 134 → neutral line connector 240 → U phase second conductive tube 112 → U phase other end first connector 2121 → U phase first conductive tube 111 → U phase line 11.

[0414] Another flow is as follows: W phase first conductive tube 131 → W phase other end first connector 2321 → W phase second conductive tube 132 → neutral line connector 240; then it branches into two paths.

[0415] Then, one of the flows is as follows: U-phase second conductive tube 112 → U-phase other end side first connector 2121 → U-phase first conductive tube 111 → U-phase line 11.

[0416] The other path is as follows: U-phase fourth conductive tube 114 → U-phase other end side second connector 2122 → U-phase third conductive tube 113 → U-phase one end side connector 211 → U-phase line 11.

[0417] According to the fifth embodiment described above, the cooling performance is excellent because the heat medium flows inside each conductive tube.

[0418] For the same current value, the heat generated by the fifth embodiment (parallel connection type) is 1 / 4 that of the series connection type as in the first embodiment. Under the same voltage and output conditions, the parallel connection type rotates twice as fast as the series connection type. Therefore, to achieve the same speed, the motor length must be doubled, resulting in approximately half the heat generated. Assuming that a speed twice that of the series connection type is acceptable, under the same voltage, output, and motor length, the heat generated is 1 / 4. This reduces heat generation. Furthermore, conversely, with the same motor size and weight, although the speed is doubled, the current is also doubled.

[0419] (Sixth Implementation Method)

[0420] Figure 30 This is an unfolded diagram of the rotary electric motor modeled in the sixth embodiment.

[0421] In each of the above-described embodiments of the rotary motor, 12 conductive tubes are arranged in the space (slot) between the teeth, making it a 12N4P type rotary motor using a 4-pole rotor.

[0422] In contrast, the rotary motor of this sixth embodiment has 12 conductive tubes arranged in the space (slot) between the teeth, and is a 12N8P type rotary motor using an 8-pole rotor. As a specific configuration, the arrangement order of the conductive tubes is different from that of the rotary motor of the first embodiment, and the connection of the conductive tubes via the connector is different.

[0423] Multiple teeth protrude from the inner peripheral wall of the base of the stator core 20. For example... Figure 30 As shown, from left to right, the teeth are: first tooth 2001, second tooth 2002, third tooth 2003, fourth tooth 2004, fifth tooth 2005, sixth tooth 2006, seventh tooth 2007, eighth tooth 2008, ninth tooth 2009, tenth tooth 2010, eleventh tooth 2011, and twelfth tooth 2012.

[0424] Conductive tubes are arranged in the spaces (grooves) between the teeth.

[0425] A U-phase first conductive tube 111 is disposed in the space (slot) between the first tooth section 2001 and the second tooth section 2002. A U-phase second conductive tube 112 is disposed in the space (slot) between the second tooth section 2002 and the third tooth section 2003. A V-phase third conductive tube 123 is disposed in the space (slot) between the third tooth section 2003 and the fourth tooth section 2004. A V-phase fourth conductive tube 124 is disposed in the space (slot) between the fourth tooth section 2004 and the fifth tooth section 2005. A W-phase first conductive tube 131 is disposed in the space (slot) between the fifth tooth section 2005 and the sixth tooth section 2006. A W-phase second conductive tube 132 is disposed in the space (slot) between the sixth tooth section 2006 and the seventh tooth section 2007. A U-phase third conductive tube 113 is disposed in the space (slot) between the seventh tooth section 2007 and the eighth tooth section 2008. A U-phase fourth conductive tube 114 is disposed in the space (slot) between the eighth tooth section 2008 and the ninth tooth section 2009. A V-phase first conductive tube 121 is disposed in the space (slot) between the ninth tooth section 2009 and the tenth tooth section 2010. A V-phase second conductive tube 122 is disposed in the space (slot) between the tenth tooth section 2010 and the eleventh tooth section 2011. A W-phase third conductive tube 133 is disposed in the space (slot) between the eleventh tooth section 2011 and the twelfth tooth section 2012. A W-phase fourth conductive tube 134 is disposed in the space (slot) between the twelfth tooth section 2012 and the first tooth section 2001.

[0589] Figure 49 This means that in Figure 46 The diagram shown illustrates the flow of current from phase W to phase U in the unfolded model. Furthermore, the arrows indicate the direction of current flow.

[0590] Next, the flow of current from the W-phase line to the U-phase line will be explained.

[0591] The current flowing into phase W line 13 flows as follows: phase W line 13 → phase W first conductive tube 131 → phase W other end first connector 2321 → phase W second conductive tube 132 → phase W one end connector 231 → phase W third conductive tube 133 → phase W other end second connector 2322 → phase W fourth conductive tube 134 → neutral line connector 240 → phase U fourth conductive tube 114 → phase U other end second connector 2122 → phase U third conductive tube 113 → phase U one end connector 211 → phase U second conductive tube 112 → phase U other end first connector 2121 → phase U first conductive tube 111 → phase U line 11.

[0592] By configuring it as described above in this embodiment, the heat transfer medium can flow inside each conductive tube in the double-turn 6N2P type rotary motor, resulting in excellent cooling performance.

[0593] Furthermore, by making it a double-turn type, the output can be improved.

[0594] Furthermore, although the description of this embodiment uses a double-turn type to avoid complicated explanation, it can also be made into a three-turn or more-turn type by increasing the number of conductive tubes arranged in the space (groove) between the teeth.

[0595] (Eleventh Implementation Method)

[0596] Figure 50 This is an unfolded diagram of the rotary electric motor modeled according to the eleventh embodiment.

[0597] This eleventh embodiment of the rotary motor has a conductive tube arranged in the space (slot) between the three teeth, and is a 3N2P type rotary motor using a 2-pole rotor. Furthermore, while the eighth embodiment is a single-turn type where the current only turns around the teeth once, this eleventh embodiment is a double-turn type where the current turns around the teeth twice.

[0598] Multiple teeth protrude from the inner peripheral wall of the base of the stator core 20. For example... Figure 50 As shown, from left to right, the teeth are the first tooth 2001, the second tooth 2002, and the third tooth 2003.

However, from an efficiency perspective, the configuration is preferred.

A first connector 2121 is connected to the other end of the first U-phase conductive tube 111 and the other end of the second U-phase conductive tube 112, thereby making the first U-phase conductive tube 111 and the second U-phase conductive tube 112 conductive.

[0609] A U-phase one-end connector 211 is connected to one end of the U-phase second conductive tube 112 and one end of the U-phase third conductive tube 113, thereby enabling the U-phase second conductive tube 112 and the U-phase third conductive tube 113 to conduct.

[0610] A second connector 2122 is connected to the other end of the U-phase third conductive tube 113 and the other end of the U-phase fourth conductive tube 114, thereby making the U-phase third conductive tube 113 and the U-phase fourth conductive tube 114 conductive.

A first connector 2221 is connected to the other end of the first V-phase conductive tube 121 and the other end of the second V-phase conductive tube 122, thereby making the first V-phase conductive tube 121 and the second V-phase conductive tube 122 conductive.

[0612] A V-phase one-end connector 221 is connected to one end of the V-phase second conductive tube 122 and one end of the V-phase third conductive tube 123, thereby enabling the V-phase second conductive tube 122 and the V-phase third conductive tube 123 to conduct.

[0614] A W-phase wire 13 is connected to one end of the first W-phase conductive tube 131. The W-phase wire 13 is a solid conductor. A first connector 2321 is connected to the other end of the first W-phase conductive tube 131 and the other end of the second W-phase conductive tube 132, thereby making the first W-phase conductive tube 131 and the second W-phase conductive tube 132 conductive.

[0615] A W-phase one-end connector 231 is connected to one end of the W-phase second conductive tube 132 and one end of the W-phase third conductive tube 133, thereby enabling the W-phase second conductive tube 132 and the W-phase third conductive tube 133 to conduct.

[0618] (Flow of the heat medium)

[0619] exist Figure 50 In the diagram, the arrows indicate the direction of flow of the heat medium.

[0620] The heat medium supplied from the first heat medium flow pipe 331 originates from the first heat medium flow area 3101 of the heat medium flow member 310 on one side, flows through any one of the U-phase first conductive pipe 111, U-phase third conductive pipe 113, U-phase second conductive pipe 112, U-phase fourth conductive pipe 114, V-phase first conductive pipe 121, and V-phase third conductive pipe 123, and reaches the heat medium flow member 320 on the other side. Then, it flows through any one of the V-phase second conductive pipe 122, V-phase fourth conductive pipe 124, W-phase first conductive pipe 131, W-phase third conductive pipe 133, W-phase second conductive pipe 132, and W-phase fourth conductive pipe 134, and reaches the second heat medium flow area 3102 of the heat medium flow member 310 on one side, and is discharged from the second heat medium flow pipe 332. Furthermore, although the heat medium is described in this embodiment as being supplied from the first heat medium flow pipe 331 and discharged from the second heat medium flow pipe 332, it may also be supplied from the second heat medium flow pipe 332 and discharged from the first heat medium flow pipe 331.

[0621] Next, the flow of electric current will be explained.

[0622] Figure 51 This means that in Figure 50 The diagram shown illustrates the flow of current from the U-phase line to the V-phase line. Furthermore, the arrows indicate the direction of current flow.

[0623] First, let's explain the flow of current from the U-phase line to the V-phase line.

[0624] The current flowing into phase U11 flows as follows: phase U11 → phase U1 ...

[0625] Figure 52 This means that in Figure 50 The diagram shown illustrates the flow of current from the V-phase line to the W-phase line. Furthermore, the arrows indicate the direction of current flow.

[0626] Next, the flow of current from the V-phase line to the W-phase line will be explained.

[0627] The current flowing into phase V line 12 flows as follows: phase V line 12 → phase V first conductive tube 121 → phase V other end first connector 2221 → phase V second conductive tube 122 → phase V one end connector 221 → phase V third conductive tube 123 → phase V other end second connector 2222 → phase V fourth conductive tube 124 → neutral line connector 240 → phase W fourth conductive tube 134 → phase W other end second connector 2322 → phase W third conductive tube 133 → phase W one end connector 231 → phase W second conductive tube 132 → phase W other end first connector 2321 → phase W first conductive tube 131 → phase W line 13.

[0628] Figure 53 This means that in Figure 50 The diagram shown illustrates the flow of current from phase W to phase U in the unfolded model. Furthermore, the arrows indicate the direction of current flow.

[0629] Next, the flow of current from the W-phase line to the U-phase line will be explained.

[0630] The current flowing into phase line 13 (W phase) flows as follows:

[0631] W-phase line 13 → W-phase first conductive tube 131 → W-phase other end first connector 2321 → W-phase second conductive tube 132 → W-phase one end connector 231 → W-phase third conductive tube 133 → W-phase other end second connector 2322 → W-phase fourth conductive tube 134 → Neutral line connector 240 → U-phase fourth conductive tube 114 → U-phase other end second connector 2122 → U-phase third conductive tube 113 → U-phase one end connector 211 → U-phase second conductive tube 112 → U-phase other end first connector 2121 → U-phase first conductive tube 111 → U-phase line 11.

[0632] By configuring it as described above in this embodiment, the heat transfer medium can flow inside each conductive tube in the double-turn 3N2P type rotary motor, resulting in excellent cooling performance.

[0633] Furthermore, by making it a double-turn type, the output can be improved.

[0634] Furthermore, although the description of this embodiment uses a double-turn type to avoid complicated explanation, it can also be made into a three-turn or more-turn type by increasing the number of conductive tubes arranged in the space (groove) between the teeth.

[0635] While embodiments of the present invention have been described above, these embodiments are merely examples of applications of the present invention and are not intended to limit the technical scope of the present invention to the specific configurations described above.

[0636] For example, in the above embodiments, the stator core is cylindrical and has multiple teeth protruding from the inner peripheral wall of the base, with conductive tubes arranged in the space (groove) between the teeth.

[0637] However, the stator core can also be flat rather than cylindrical. Furthermore, it can be constructed with multiple teeth protruding from the bottom surface, which serves as the base, and conductive tubes arranged in the spaces (slots) between the teeth. With this construction, the invention can be applied to linear motors.

[0638] Furthermore, in the above embodiments, a plurality of teeth protrude from the base of the stator core, and a conductive tube is disposed in the space (groove) between the teeth.

[0639] However, as recorded in Japanese Patent Application Publication No. 2002-101591, there is a known slotless rotary electric machine (electromechanical energy converter) in which a hollow coil is provided on the inner circumferential surface of a stator core that does not have teeth or slots.

[0640] If we take an example of the stator of such a rotating electric machine, it would become like... Figure 54 As shown.

[0641] Figure 54 It is a three-dimensional view of the stator of a slotless rotary electric machine, which cuts out and represents a portion of the stator core.

[0642] In one example, the stator 2 of a slotless rotary electric machine is configured such that the coil 23, disposed inside the stator core 21 via an insulating sheet 201, is further held in place by an inner protective layer 202. Furthermore, in Figure 54 Although coil 23 is only wound once to avoid visual clutter, it is actually wound multiple times as needed. Furthermore, the insulating sheet or protective layer can be replaced by other units or be an unused structure. Slotless rotary motors can reduce cogging torque, demagnetization, iron loss, and drift loss.

[0643] The electro-mechanical energy converter (rotary motor / linear motor) of the present invention may also be of this slotless, coreless type.

[0644] Furthermore, in the above embodiments, the heat medium flow member has a dual-body structure consisting of a body and a cover, but the body may also serve as a motor housing. For example, in the fourth embodiment, the heat medium flow member 310 has a dual-body structure consisting of a cover plate (body) 311 and a base plate (cover) 312. However, it may also be configured as follows: Figure 55 As shown, the cover plate (body part) 311 is also used as the motor housing, as... Figure 56 As shown, this illustrates the bolt fastening mechanism.

[0645] Furthermore, although a flat shape was given as an example of the conductive tube 100 in the above embodiments, it is also possible to use a shape such as... Figure 57 As shown, it is cylindrical.

[0646] Furthermore, it can also be like Figure 58 As shown, this is a form with multiple pathways.

[0647] Furthermore, in Figure 24 (Fourth Implementation) and Figure 55 In this configuration, if a thin coating material is applied to the inner circumference of the stator core 20 after the conductive tubes 111, 112, ... are positioned, the positions of the conductive tubes 111, 112, ... are fixed. Then, the cover plates 311 and 321 are further liquid-tightly fixed to the stator core 20 using the configuration described above. With the configuration described above, the base plates 312 and 322 can be removed.

[0648] Alternatively, a groove sealing member can be added to the inner circumference of the stator core 20 instead of coating the inner circumference of the stator core 20 with a coating material. Excellent productivity is achieved when the positions of the conductive tubes 111, 112, ... are fixed using the member described above.

[0649] Furthermore, there are no restrictions on the type of rotary motor. For example, it can also be applied to axial flux rotary motors, SR rotary motors, induction rotary motors, synchronous rotary motors, etc.

[0650] For example, by changing the heat transfer medium to liquid nitrogen or liquid helium, a superconducting rotating motor can be constructed.

[0651] Furthermore, the heat transfer medium used can be a liquid insulating heat transfer medium, a gas such as air, or, in addition, antifreeze, liquefied chlorofluorocarbons / halogenated hydrocarbons, liquefied hydrocarbons, silicone oils, liquefied ammonia, liquefied nitrogen, liquefied hydrogen, liquefied rare gases, liquefied carbon dioxide, etc. In heat transfer media such as water, pure water with very low conductivity can be appropriately mixed with additives to prevent corrosion, etc.

[0652] Furthermore, by coating the inside of the conductive tube with an insulating film, it becomes possible to use a conductive thermal medium, such as an aqueous liquid.

[0653] By replacing the heat medium with an extremely low temperature heat medium such as liquid nitrogen or liquid helium, and using a superconducting material as a conductive tube, a superconducting rotating motor can be constructed.

[0654] Furthermore, ion exchange resin filters can be installed along the heat transfer medium path. This allows ions to be removed from the heat transfer medium beforehand, reducing its conductivity and improving its insulation. Even if a leak occurs in the conductive heat transfer medium, leakage can be minimized.

[0655] In addition to using pumps or other power sources to circulate the heat medium for cooling, a natural circulation method, such as using gravity, can also be employed, without the use of pumps, as in heat pipes.

[0656] Although there are various winding methods for motors, such as concentrated winding, distributed winding, single-layer winding, double-layer winding, full-pitch winding, short-pitch winding, overlapping winding, concentric winding, and wave winding, these methods can be combined and appropriately selected during the design process.

[0657] It is also possible to manufacture a type where the stator slot teeth are closed (without coil end heat medium flow path connection parts).

[0658] Furthermore, although the connector is in Figure 3 The solid type is one example, but it can also be a hollow type where the flow path is formed by the hot medium flowing from the front end through the interior to the other end.

[0659] Furthermore, it can also provide appropriate cooling from the outside of the stator core at the same time.

[0660] Regarding connectors, examples are provided in the above embodiments. Figure 3The connector shown is of a specific shape. However, this shape is merely an example, and there are no limitations on the shape of the connector. Furthermore, the connector can also use general-purpose wires such as magnetic wires or stranded wires.

[0661] Furthermore, the above-described embodiments can be combined appropriately.

[0662] For example, the heat medium flow member 310 used on one side of the second embodiment and the heat medium flow member 320 used on the other side are applied in the fifth embodiment. In this case, it becomes as follows: Figure 59 As shown.

[0663] Furthermore, the heat medium flow member used in the fourth embodiment is applied in the third embodiment, becoming as follows: Figure 60 As shown.

[0664] As described above, the above embodiments can be appropriately combined.

[0665] This application claims priority based on Japan Patent Application No. 2023-126263, filed with the Japan Patent Office on August 2, 2023, the entire contents of which are incorporated herein by reference.
