DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0028] (First embodiment) FIG. 1 shows the stator of the prototype electrical energy-mechanical energy converter.

[0029] In the following description, unless otherwise specified, the electric energy mechanical energy converter will be described taking as an example a rotating electric machine that functions as an electric motor or a generator.

[0030] Fig. 1 shows a stator core, which is a characteristic configuration of a rotating electric machine according to this embodiment. Note that Fig. 1 shows a stator core used in an inner rotor type rotating electric machine, but this is just one example. The gist of the present invention may also be applied to an outer rotor type rotating electric machine.

[0031] As shown in Fig. 1, stator core 20 is cylindrical and has a structure in which a plurality of teeth 2001, 2002, ... are protruding from the inner peripheral wall of a base portion. In Fig. 1, 192 teeth are protruding. Stator core 20 is formed by laminating thin electromagnetic steel sheets.

[0032] FIG. 2 is a diagram showing an example of a conductive tube.

[0033] The conductive pipe 100 is conductive and allows a heat transfer medium to flow through it. The surface is insulated with insulating varnish or the like. The heat transfer medium flows through the inner periphery, and this inner periphery may also be insulated with insulating varnish or the like. Although a flat shape is shown as an example of the conductive pipe 100 in FIG. 2, it may also be cylindrical.

[0034] The conductive tube 100 is disposed in a space (slot) between the teeth of the stator core 20. Since the conductive tube 100 is longer than the thickness of the stator core 20, when the conductive tube 100 is disposed in the slot of the stator core 20, it protrudes on both sides of the stator core 20.

[0035] FIG. 3 is a diagram showing an example of a connector. As described above, the conductive tube 100 is longer than the thickness of the stator core 20, and therefore protrudes on both sides of the stator core 20 when placed in the slot of the stator core 20. The connector is connected to this protruding portion to allow electrical current to flow between specific conductive tubes. The connector 200 shown in FIG. 3 is placed on the outer periphery of the stator core 20 and is connected to the conductive tube 100 from the outer periphery. However, this is merely an example. The connector 200 may be placed on the inner periphery of the stator core 20 and connected to the conductive tube 100 from the inner periphery.

[0036] FIG. 4 is a side view of the stator.

[0037] A conductive tube 100 is disposed in a space (slot) between the teeth of the stator core 20, and a connector 200 is connected to a portion protruding from both sides of the stator core 20. Specific connection points etc. will be described later.

[0038] FIG. 5 is a view of the stator seen obliquely from above.

[0039] As described above, the connectors 200 are connected to the conductive tubes 100 protruding from both sides of the stator core 20. Above and below the stator core 20, resin (insulating) heat medium flow members 300 (310, 320) are disposed.

[0040] FIG. 6 is an enlarged view of the heat medium flow member disposed above the stator core and its vicinity, as viewed obliquely from above.

[0041] A hole having the same shape as the conductive pipe 100 is formed in the bottom surface of the heat medium flow member 310, and the conductive pipe 100 is inserted into this hole. The portion of the conductive pipe 100 inserted into the hole is liquid-tight so that the heat medium does not leak out. Although not shown in Figures 5 and 6, the heat medium flow member 310 has a lid portion so that the heat medium does not leak out from the heat medium flow member 310 to the outside.

[0042] FIG. 7 is an exploded view showing an example of a rotating electric machine.

[0043] 1 to 6, a stator core 20 is provided with 192 teeth protruding therefrom, and 192 conductive tubes are arranged in the spaces (slots) between the teeth. However, this structure is very complicated. Therefore, in the following, for ease of understanding, a simplified structure will be described. However, these are not mere models. Of course, these also work.

[0044] The rotating electric machine 1 shown in Fig. 7 has a structure in which 12 teeth are protrudingly provided on a stator core 20, and 12 conductive tubes are arranged in the spaces (slots) between the teeth. The rotor 50 is a four-pole type, and the rotating electric machine in Fig. 7 is a 12N4P type.

[0045] The stator core 20 is formed by laminating thin electromagnetic steel sheets. The stator core 20 has 12 teeth protruding from the inner peripheral wall of the base portion. Then, 12 conductive tubes 111, 112, ... are arranged in the spaces (slots) between the teeth. Since the conductive tubes are longer than the thickness of the stator core 20, they protrude on both sides of the stator core 20 when arranged in the slots of the stator core 20. Connectors 211, 221, ... are connected to these protruding parts, allowing electrical current to flow between specific conductive tubes. Details will be described later.

[0046] Furthermore, heat medium flow members 310, 320 are disposed on both sides of the stator core 20. Into holes of these heat medium flow members 310, 320, the conductive pipes 111, 112, . . . are inserted.

[0047] The heat medium flow member 310 includes a main body 311 and a lid 312. The main body 311 has a flow path through which the heat medium flows. The flow path is divided into two by a pair of partitions 3100. A first heat medium flow pipe 331 for supplying or discharging the heat medium is connected to one of the sections (first heat medium flow section 3101). A second heat medium flow pipe 332 for supplying or discharging the heat medium is connected to the other section (second heat medium flow section 3102). The lid 312 is fixed to the main body 311 in a liquid-tight manner so that the heat medium flowing through the flow path of the main body 311 does not leak to the outside.

[0048] The heat medium flow member 320 includes a main body 321 and a lid 322. A flow path through which the heat medium flows is formed in the main body 321. The lid 322 is fixed to the main body 321 in a liquid-tight manner so that the heat medium flowing through the flow path of the main body 321 does not leak to the outside.

[0049] A U-phase wire 11 is connected to one of the U-phase conductor pipes among the twelve conductor pipes. A V-phase wire 12 is connected to one of the V-phase conductor pipes among the twelve conductor pipes. A W-phase wire 13 is connected to one of the W-phase conductor pipes among the twelve conductor pipes.

[0050] 8A and 8B are assembly diagrams of the rotating electric machine shown in FIG. 7, where FIG. 8A is a diagram seen from an oblique left side, and FIG. 8B is a diagram seen from an oblique right side. 8(A) and 8(B), it can be seen that heat medium flow members 310, 320 are arranged on both sides of the stator core 20. Also, in Fig. 8(B), it can be seen that the heat medium flow member 310 is provided with a first heat medium flow pipe 331 and a second heat medium flow pipe 332. It can also be seen that the U phase wire 11, the V phase wire 12, and the W phase wire 13 protrude.

[0051] FIG. 9 is a development view in which the rotating electric machine shown in FIG. 7 is modeled.

[0052] A plurality of teeth are provided protruding from the inner peripheral wall of the base portion of the stator core 20.

A W-phase fourth conductive tube 134 is arranged in the space (slot) between the sixth teeth 2006 and the seventh teeth 2007. A U-phase third conductive tube 113 is disposed in a space (slot) between the seventh teeth 2007 and the eighth teeth 2008.

[0061] A U-phase other end second connector 2122 is connected to the other end of the U-phase third conductive pipe 113 and the other end of the U-phase fourth conductive pipe 114, so that the U-phase third conductive pipe 113 and the U-phase fourth conductive pipe 114 are electrically connected.

[0062] The V-phase wire 12 is connected to one end of the V-phase first conductive pipe 121. The V-phase wire 12 is a solid conductor.

[0063] A V-phase one-end connector 221 is connected to one end of the V-phase second conductive pipe 122 and one end of the V-phase third conductive pipe 123, and the V-phase second conductive pipe 122 and the V-phase third conductive pipe 123 are electrically connected.

[0069] Fig. 10 is a diagram for explaining the flow of the heat medium in the model development diagram shown in Fig. 9. The arrows indicate the direction in which the heat medium flows.

[0070] The heat medium supplied from the first heat medium flow pipe 331 flows from the first heat medium flow section 3101 of one heat medium flow member 310 through any one of the U-phase first conductive pipe 111, the V-phase fourth conductive pipe 124, the W-phase third conductive pipe 133, the U-phase second conductive pipe 112, the V-phase first conductive pipe 121, and the W-phase fourth conductive pipe 134 to reach the other heat medium flow member 320.

[0071] Next, the flow of electricity will be described. Fig. 11 is a diagram for explaining the flow of electricity from the U phase wire to the V phase wire in the model development diagram shown in Fig. 9. Note that the arrows indicate the direction of electricity flow.

[0072] First, a case where electricity flows from U phase wire 11 to V phase wire 12 will be described. The electricity entering through the U-phase wire 11 flows in the following order: U-phase wire 11 → U-phase first conductor tube 111 → U-phase other end first connector 2121 → U-phase second conductor tube 112 → U-phase one end connector 211 → U-phase third conductor tube 113 → U-phase other end second connector 2122 → U-phase fourth conductor tube 114 → neutral wire connector 240 → V-phase fourth conductor tube 124 → V-phase other end second connector 2222 → V-phase third conductor tube 123 → V-phase one end connector 221 → V-phase second conductor tube 122 → V-phase other end first connector 2221 → V-phase first conductor tube 121 → V-phase wire 12.

[0073] Fig. 12 is a diagram for explaining the flow of electricity from the V-phase wire to the W-phase wire in the model development diagram shown in Fig. 9. Note that the arrows indicate the direction of electricity flow.

[0074] Next, a case where electricity flows from V phase wire 12 to W phase wire 13 will be described. The electricity entering through the V-phase wire 12 flows in the following order: V-phase wire 12 → V-phase first conductor tube 121 → V-phase other end first connector 2221 → V-phase second conductor tube 122 → V-phase one end connector 221 → V-phase third conductor tube 123 → V-phase other end second connector 2222 → V-phase fourth conductor tube 124 → neutral wire connector 240 → W-phase fourth conductor tube 134 → W-phase other end second connector 2322 → W-phase third conductor tube 133 → W-phase one end connector 231 → W-phase second conductor tube 132 → W-phase other end first connector 2321 → W-phase first conductor tube 131 → W-phase wire 13.

[0075] Fig. 13 is a diagram for explaining the flow of electricity from the W-phase wire to the U-phase wire in the model development diagram shown in Fig. 9. Note that the arrow indicates the direction of electricity flow.

[0076] Next, a case where electricity flows from W phase wire 13 to U phase wire 11 will be described. The electricity entering through the W-phase wire 13 flows in the following order: W-phase wire 13 → W-phase first conductor tube 131 → W-phase other end first connector 2321 → W-phase second conductor tube 132 → W-phase one end connector 231 → W-phase third conductor tube 133 → W-phase other end second connector 2322 → W-phase fourth conductor tube 134 → neutral wire connector 240 → U-phase fourth conductor tube 114 → U-phase other end second connector 2122 → U-phase third conductor tube 113 → U-phase one end connector 211 → U-phase second conductor tube 112 → U-phase other end first connector 2121 → U-phase first conductor tube 111 → U-phase wire 11.

[0077] According to the present embodiment described above, the heat medium flows inside each conductive tube, and therefore the cooling performance is excellent.

[0078] Moreover, the conductive tubes are arranged in the spaces (slots) between the teeth of the stator core 20, and are held by inserting one end of each conductive tube into a hole formed in one heat medium flow member 310 and the other end into a hole formed in the other heat medium flow member 320. This eliminates the need to wind a conductor around the teeth as in a typical rotating electric machine, resulting in excellent productivity.

[0079] Furthermore, the heat medium is supplied from the first heat medium flow pipe 331 provided in one of the heat medium flow members 310, flows from the first heat medium flow section 3101 through one of the conductive pipes, reaches the other heat medium flow member 320, flows through another conductive pipe, reaches the second heat medium flow section 3102 of the one of the heat medium flow members 310, and is discharged from the second heat medium flow pipe 332. In this way, since both the supply point and the discharge point of the heat medium are provided in one of the heat medium flow members 310, the rotating electric machine of this embodiment has excellent mountability when attached to equipment.

[0080] Second embodiment FIG. 14 is an exploded view showing a rotating electric machine according to a second embodiment. In the following, parts that perform the same functions as those described above will be given the same reference numerals and duplicated explanations will be omitted as appropriate.

[0081] In the second embodiment, the shapes of one heat medium flow member 310 and the other heat medium flow member 320 are different from those in the first embodiment. That is, while the inside of one heat medium flow member 310 in the first embodiment is divided into two by a pair of partitions 3100, one heat medium flow member 310 in this second embodiment does not have a partition. And, a first heat medium flow pipe 331 through which the heat medium flows is connected to one heat medium flow member 310 in the second embodiment, but a second heat medium flow pipe 332 through which the heat medium flows is not connected.

[0082] The second heat medium flow pipe 332 is connected to the other heat medium flow member 320 .

[0083] 15A and 15B are assembly views of the rotating electric machine shown in FIG. 14, where FIG. 15A is a view seen from an oblique left side, and FIG. 15B is a view seen from an oblique right side. Fig. 15(A) shows that the other heat medium flow member 320 is provided with a second heat medium flow pipe 332. Fig. 15(B) shows that the other heat medium flow member 310 is provided with a first heat medium flow pipe 331.

[0084] Fig. 16 is a development view of a model of the rotating electrical machine shown in Fig. 14. Note that the arrows indicate the direction of flow of the heat medium.

[0085] Conductive tubes are disposed in spaces (slots) between the teeth of the stator core 20. The arrangement of the teeth and conductive tubes, the connection configuration of the connectors, and the like are similar to those in the first embodiment, and therefore will not be described.

[0086] One heat medium flow member 310 is disposed above (one end side of) the stator core 20. A first heat medium flow pipe 331 for supplying or discharging the heat medium is connected to one heat medium flow member 310. A second heat medium flow pipe 332 for supplying or discharging the heat medium is connected to the other heat medium flow member 320.

[0087] The heat medium supplied from the first heat medium flow pipe 331 flows from one heat medium flow member 310 through any one of the U-phase first conductive pipe 111, the V-phase fourth conductive pipe 124, the W-phase third conductive pipe 133, the U-phase second conductive pipe 112, the V-phase first conductive pipe 121, the W-phase fourth conductive pipe 134, the U-phase third conductive pipe 113, the V-phase second conductive pipe 122, the W-phase first conductive pipe 131, the U-phase fourth conductive pipe 114, the V-phase third conductive pipe 123, and the W-phase second conductive pipe 132, before reaching the other heat medium flow member 320 and being discharged from the second heat medium flow pipe 332. In this embodiment, the heat medium is described as being supplied from the first heat medium pipe 331 and discharged from the second heat medium pipe 332, but the heat medium may be supplied from the second heat medium pipe 332 and discharged from the first heat medium pipe 331.

[0088] As described above, the second embodiment also has excellent cooling performance because the heat medium flows inside each conductive tube. In particular, in the second embodiment, the heat medium is supplied from the first heat medium flow pipe 331 provided in one heat medium flow member 310, flows from the first heat medium flow section 3101 through one of the conductive tubes, reaches the other heat medium flow member 320, and is discharged from the second heat medium flow pipe 332. In this way, the flow distance of the heat medium is short, so the cooling performance is even better than that of the first embodiment.

[0089] In addition, since all the heat medium flows in one direction (from top to bottom in FIG. 16), the flow resistance of the heat medium is small, and the output of heat medium supply equipment such as pumps can be kept low.

[0090] Third embodiment FIG. 17 is an exploded view showing a rotating electric machine according to a third embodiment.

[0091] In the first and second embodiments described above, one heat medium flow member 310 and the other heat medium flow member 320 are arranged on both sides of the stator core 20. In contrast, in this third embodiment, the heat medium flow member 310 is arranged only on one side of the stator core 20, and no heat medium flow member is arranged on the other side. The other ends of the conductive tubes are connected by connector tubes.

[0092] The heat medium flow member 310 includes a first body portion 3111, a second body portion 3112, and a lid portion 312. A flow path through which the heat medium flows is formed in the first body portion 3111 and the second body portion 3112. A first heat medium flow pipe 331 for supplying or discharging the heat medium is connected to the first body portion 3111. A second heat medium flow pipe 332 for supplying or discharging the heat medium is connected to the second body portion 3112. The second body portion 3112 is fixed to the first body portion 3111 in a liquid-tight manner so that the heat medium flowing through the flow path of the first body portion 3111 does not leak to the outside. The lid portion 312 is fixed to the second body portion 3112 in a liquid-tight manner so that the heat medium flowing through the flow path of the second body portion 3112 does not leak to the outside.

[0093] 18A and 18B are assembly views of the rotating electric machine shown in FIG. 17, with FIG. 18A being a view seen from an oblique left angle, and FIG. 18B being a view seen from an oblique right angle. 18(A), the other end of each conductive tube is connected to a connector tube 2131, 2132, . . . 18(B), it can be seen that the heat medium flow member 310 is provided with a first heat medium flow pipe 331 and a second heat medium flow pipe 332. The details will be described later.

[0094] FIG. 19 is a development view in which the rotating electric machine shown in FIG. 17 is modeled.

[0095] Conductive tubes are disposed in spaces (slots) between the teeth of the stator core 20. The arrangement of the teeth and conductive tubes is the same as in the first embodiment, and therefore will not be described.

[0096] A heat medium flow member 310 is disposed above (on one end side of) the stator core 20. The heat medium flow member 310 includes a first body portion 3111, a second body portion 3112, and a lid portion 312. The second body portion 3112 is fixed to the first body portion 3111 in a liquid-tight manner so that the heat medium flowing through the flow path of the first body portion 3111 does not leak to the outside. The lid portion 312 is fixed to the second body portion 3112 in a liquid-tight manner so that the heat medium flowing through the flow path of the second body portion 3112 does not leak to the outside. With this structure, the flow path through which the heat medium flows formed inside the heat medium flow member 310 is divided into two stages, an upper stage and a lower stage. A first heat medium flow pipe 331 for supplying or discharging the heat medium is connected to one of the sections (first heat medium flow section 3101) on the first body portion 3111 side. A second heat medium flow pipe 332 for discharging or supplying the heat medium is connected to the other section (second heat medium flow section 3102) on the second main body portion 3112 side.

[0097] Twelve holes are formed in the bottom surface of the first main body portion 3111. The second main body portion 3112 has six holes formed.

With this configuration, the V-phase third conductive pipe 123 and the V-phase fourth conductive pipe 124 are electrically conductive and allow a heat medium to flow therethrough.

[0106] The W-phase wire 13 is connected to one end of the W-phase first conductive tube 131. The W-phase wire 13 is a solid conductor. The W-phase other end first connector tube 2331 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.

[0110] FIG. 20 is a diagram for explaining the flow of the heat medium in the model development diagram shown in FIG.

[0111] The heat medium supplied from the first heat medium flow pipe 331 flows from the first heat medium flow section 3101 in a first flow direction from the U-phase first conductive pipe 111 → the U-phase other end side first connector pipe 2131 → the U-phase second conductive pipe 112, and reaches the second heat medium flow section 3102.

[0112] The second flow passes through the U-phase third conducting pipe 113 → the U-phase other end side second connector pipe 2132 → the U-phase fourth conducting pipe 114 , and reaches the second heat medium flow section 3102 .

[0113] The third flow passes through the V-phase first conductive pipe 121 → the V-phase other end side first connector pipe 2231 → the V-phase second conductive pipe 122 , and reaches the second heat medium flow section 3102 .

[0114] The fourth flow passes through the V-phase third conducting pipe 123 → the V-phase other end side second connector pipe 2232 → the V-phase fourth conducting pipe 124 , and reaches the second heat medium flow section 3102 .

[0115] The fifth flow passes through the W-phase first conductive pipe 131 → the W-phase other end side first connector pipe 2331 → the W-phase second conductive pipe 132 , and reaches the second heat medium flow section 3102 .

[0116] The sixth flow is from the W-phase third conductive pipe 133 to the W-phase other end side second connector pipe 2332 to the W-phase fourth conductive pipe 134 , and reaches the second heat medium flow section 3102 .

[0117] The heat medium reaches the second heat medium flow section 3102 in this manner, and is discharged from the second heat medium flow pipe 332. Note that, although this embodiment has been described as being supplied from the first heat medium flow pipe 331 and discharged from the second heat medium flow pipe 332, the heat medium may be supplied from the second heat medium flow pipe 332 and discharged from the first heat medium flow pipe 331.

[0118] Next, the flow of electricity will be described. Fig. 21 is a diagram for explaining the flow of electricity from the U phase wire to the V phase wire in the model development diagram shown in Fig. 19. Note that the arrows indicate the direction of electricity flow.

[0119] First, a case where electricity flows from U phase wire 11 to V phase wire 12 will be described. The electricity entering through the U-phase wire 11 flows as follows: U-phase wire 11 → U-phase first conductor tube 111 → U-phase other end first connector tube 2131 → U-phase second conductor tube 112 → U-phase connector 211 → U-phase third conductor tube 113 → U-phase other end second connector tube 2132 → U-phase fourth conductor tube 114 → neutral wire connector 240 → V-phase fourth conductor tube 124 → V-phase other end second connector tube 2232 → V-phase third conductor tube 123 → V-phase connector 221 → V-phase second conductor tube 122 → V-phase other end first connector tube 2231 → V-phase first conductor tube 121 → V-phase wire 12.

[0120] Fig. 22 is a diagram for explaining the flow of electricity from the V-phase wire to the W-phase wire in the model development diagram shown in Fig. 19. Note that the arrows indicate the direction of electricity flow.

[0121] Next, a case where electricity flows from V phase wire 12 to W phase wire 13 will be described. The electricity entering through the V-phase wire 12 flows as follows: V-phase wire 12 → V-phase first conductor tube 121 → V-phase other end first connector tube 2231 → V-phase second conductor tube 122 → V-phase connector 221 → V-phase third conductor tube 123 → V-phase other end second connector tube 2232 → V-phase fourth conductor tube 124 → neutral wire connector 240 → W-phase fourth conductor tube 134 → W-phase other end second connector tube 2332 → W-phase third conductor tube 133 → W-phase connector 231 → W-phase second conductor tube 132 → W-phase other end first connector tube 2331 → W-phase first conductor tube 131 → W-phase wire 13.

[0122] Fig. 23 is a diagram for explaining the flow of electricity from the W-phase wire to the U-phase wire in the model development diagram shown in Fig. 19. Note that the arrows indicate the direction of electricity flow.

[0123] Next, a case where electricity flows from W phase wire 13 to U phase wire 11 will be described. The electricity entering through the W-phase wire 13 flows as follows: W-phase wire 13 → W-phase first conductor tube 131 → W-phase other end first connector tube 2331 → W-phase second conductor tube 132 → W-phase connector 231 → W-phase third conductor tube 133 → W-phase other end second connector tube 2332 → W-phase fourth conductor tube 134 → neutral wire connector 240 → U-phase fourth conductor tube 114 → U-phase other end second connector tube 2132 → U-phase third conductor tube 113 → U-phase connector 211 → U-phase second conductor tube 112 → U-phase other end first connector tube 2131 → U-phase first conductor tube 111 → U-phase wire 11.

[0124] As described above, according to the third embodiment as well, the heat medium flows inside each conductive tube, and therefore the cooling performance is excellent.

[0125] In the first and second embodiments, one heat medium flow member 310 and the other heat medium flow member 320 are arranged on both sides of the stator core 20. In contrast, in the third embodiment, a heat medium flow member is arranged only on one side of the stator core 20, and no heat medium flow member is arranged on the other side. With this configuration, the size is compact.

[0126] Furthermore, since the supply points and discharge points of the heat medium are both provided in the heat medium flow member, the rotating electric machine of this embodiment has excellent mountability when mounted on equipment.

[0127] Furthermore, in the first embodiment, the heat medium supplied from the first heat medium flow pipe 331 passes through one of the conductive pipes from the first heat medium flow section 3101 of one heat medium flow member 310, reaches the other heat medium flow member 320, and passes through one of the conductive pipes to reach the second heat medium flow section 3102 of the one heat medium flow member 310. At this time, in the other heat medium flow member 320, the flows of the heat medium interfere with each other, and there is a possibility that the heat medium will not flow smoothly. In contrast, in the third embodiment, the heat medium flows in one direction inside the connector pipe, so that the flow resistance of the heat medium is small and the output of heat medium supplying equipment such as a pump can be kept low.

[0128] (Fourth embodiment) FIG. 24 is an exploded view showing a rotating electric machine according to a third embodiment. In each of the above-described embodiments, each connector is connected to a conductive tube protruding from the stator core 20. An end of the conductive tube is inserted into a hole formed in the bottom surface of the heat medium flow member. That is, each connector is disposed between the stator core 20 and the heat medium flow member.

[0129] In contrast to this, in the fourth embodiment, each connector is disposed inside the heat medium flow member. That is, the heat medium flow member 310 includes a cover 311 and a bottom plate 312. The bottom plate 312 has 12 holes formed therein. A pair of partitions 3100 are also formed therein. Ends of the conductive pipes are inserted into the holes in the bottom plate 312, and connectors are connected to the conductive pipes protruding from the bottom plate 312. The cover 311 is fixed to the bottom plate 312.

[0130] 25A and 25B are assembly diagrams of the rotating electric machine shown in FIG. 24, where FIG. 25A is a diagram seen from an oblique left side, and FIG. 25B is a diagram seen from an oblique right side.

[0131] 25(A) and 25(B), it can be seen that the heat medium flow members are arranged on both sides of the stator core 20, and the connectors are not visible. Also, from Fig. 25(B), it can be seen that the heat medium flow member is provided with a first heat medium flow pipe 331 and a second heat medium flow pipe 332.

[0132] Fig. 26 is a development view of a model of the rotating electrical machine shown in Fig. 24. Note that the arrows indicate the direction of flow of the heat medium.

[0133] A conductive tube is disposed in a space (slot) between the teeth of the stator core 20. One end of the conductive tube is inserted into a hole formed in the bottom plate 312 of one heat medium flow member 310. Then, each connector is connected to the conductive tube protruding from the bottom plate 312. Then, the cover 311 is fixed to the bottom plate 312. The other end of the conductive tube is inserted into a hole formed in the bottom plate 322 of the other heat medium flow member 320. Then, each connector is connected to the conductive tube protruding from the bottom plate 322. Then, the cover 321 is fixed to the bottom plate 322. The arrangement of the teeth and conductive tubes, the connection configuration of the connectors, and the like are similar to those in the first embodiment, and therefore will not be described.

[0134] As shown by the arrows, the heat medium supplied from the first heat medium flow pipe 331 flows into the first heat medium flow section 3101 of one heat medium flow member 310. Here, the heat medium cools each connector in the first heat medium flow section 3101. Then, the heat medium flows through any one of the U-phase first conductive pipe 111, the V-phase fourth conductive pipe 124, the W-phase third conductive pipe 133, the U-phase second conductive pipe 112, the V-phase first conductive pipe 121, and the W-phase fourth conductive pipe 134, and reaches the other heat medium flow member 320. Here, the heat medium cools each connector in the other heat medium flow member 320. Then, the heat medium flows through any one of the U-phase third conductive pipe 113, the V-phase second conductive pipe 122, the W-phase first conductive pipe 131, the U-phase fourth conductive pipe 114, the V-phase third conductive pipe 123, and the W-phase second conductive pipe 132, and reaches the second heat medium flow section 3102 of one heat medium flow member 310. Here, the heat medium cools each connector in the second heat medium flow section 3102. Then, the heat medium is discharged from the second heat medium flow pipe 332. Note that, in this embodiment, the heat medium is described as being supplied from the first heat medium flow pipe 331 and discharged from the second heat medium flow pipe 332, but may be supplied from the second heat medium flow pipe 332 and discharged from the first heat medium flow pipe 331.

[0135] The flow of electricity is basically the same as in the first embodiment, so a description thereof will be omitted here.

[0136] According to the fourth embodiment described above, the connectors are disposed inside the heat medium flow member and are cooled by the heat medium flowing through the heat medium flow member, resulting in excellent cooling performance.

[0137] In addition, since each connector is disposed inside the heat medium flow member and is not exposed, it is possible to prevent foreign matter from getting between the connectors, and maintenance is easy.

[0138] Fifth embodiment FIG. 27 is a development view in which the rotating electric machine of the fifth embodiment is modeled.

[0139] The rotating electric machine of the fifth embodiment is different from the rotating electric machine of the first embodiment in the connection of the conductive tubes by the connector. The arrangement order of the teeth and the conductive tubes is the same as that of the first embodiment, so a description thereof will be omitted. In addition, the configuration of the heat medium flow member and the flow of the heat medium are also the same as those of the first embodiment, so a description thereof will be omitted.

[0140] The U-phase wire 11 is connected to one end of the U-phase first conductive pipe 111. A U-phase one-end connector 211 is connected to one end of the U-phase first conductive pipe 111 and one end of the U-phase third conductive pipe 113, and the U-phase first conductive pipe 111 and the U-phase third conductive pipe 113 are electrically connected to each other.

[0141] A U-phase other end first connector 2121 is connected to the other end of the U-phase first conductive pipe 111 and the other end of the U-phase second conductive pipe 112, and the U-phase first conductive pipe 111 and the U-phase second conductive pipe 112 are electrically connected.

[0142] A U-phase other end second connector 2122 is connected to the other end of the U-phase third conductive pipe 113 and the other end of the U-phase fourth conductive pipe 114, so that the U-phase third conductive pipe 113 and the U-phase fourth conductive pipe 114 are electrically connected.

[0143] The V-phase wire 12 is connected to one end of the V-phase first conductive pipe 121. A V-phase one-end connector 221 is connected to one end of the V-phase first conductive pipe 121 and one end of the V-phase third conductive pipe 123, and the V-phase first conductive pipe 121 and the V-phase third conductive pipe 123 are electrically connected to each other.

[0144] A V-phase other end first connector 2221 is connected to the other end of the V-phase first conductive pipe 121 and the other end of the V-phase second conductive pipe 122, so that the V-phase first conductive pipe 121 and the V-phase second conductive pipe 122 are electrically connected.

[0145] A V-phase other end second connector 2222 is connected to the other end of the V-phase third conductive pipe 123 and the other end of the V-phase fourth conductive pipe 124, and the V-phase third conductive pipe 123 and the V-phase fourth conductive pipe 124 are electrically connected.

[0146] The W-phase wire 13 is connected to one end of the W-phase first conductive pipe 131. A W-phase one-end connector 231 is connected to one end of the W-phase first conductive pipe 131 and one end of the W-phase third conductive pipe 133, and the W-phase first conductive pipe 131 and the W-phase third conductive pipe 133 are electrically connected to each other.

[0147] A W-phase other end first connector 2321 is connected to the other end of the W-phase first conductive pipe 131 and the other end of the W-phase second conductive pipe 132, so that the W-phase first conductive pipe 131 and the W-phase second conductive pipe 132 are electrically connected.

[0148] A W-phase other end second connector 2322 is connected to the other end of the W-phase third conductive pipe 133 and the other end of the W-phase fourth conductive pipe 134, so that the W-phase third conductive pipe 133 and the W-phase fourth conductive pipe 134 are electrically connected.

[0149] A neutral wire 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, so that the U-phase second conductive tube 112, the U-phase fourth conductive tube 114, the V-phase second conductive tube 122, the V-phase fourth conductive tube 124, the W-phase second conductive tube 132, and the W-phase fourth conductive tube 134 are electrically conductive.

[0150] Next, we will explain the flow of electricity from the U phase wire to the V phase wire. Note that the arrows indicate the direction of electricity flow. Electricity entering from U phase wire 11 branches into two. In the first embodiment and the like, electricity flows from U phase wire to V phase wire without branching, which is a series connection type. In contrast, in this fifth embodiment, electricity branches and then merges, which is a parallel connection type.

[0151] One of the branched paths flows from the U-phase one end connector 211 → the U-phase third conductive pipe 113 → the U-phase other end second connector 2122 → the U-phase fourth conductive pipe 114 → the neutral wire connector 240 → the V-phase second conductive pipe 122 → the V-phase other end first connector 2221 → the V-phase first conductive pipe 121 → the V-phase wire 12.

[0152] The other flow passes through the U-phase first conductive pipe 111, the U-phase other end side first connector 2121, the U-phase second conductive pipe 112, and the neutral wire connector 240, and then branches into two. One flows from the V-phase second conductive pipe 122 → the V-phase other end side first connector 2221 → the V-phase first conductive pipe 121 → the V-phase wire 12 . The other current flows from the V-phase fourth conducting tube 124 → the V-phase other end side second connector 2222 → the V-phase third conducting tube 123 → the V-phase one end side connector 221 → the V-phase wire 12 .

[0153] Figure 28 is a diagram for explaining the flow of electricity from the V-phase wire to the W-phase wire in the model development diagram shown in Figure 27. Note that the arrows indicate the direction of electricity flow.

[0154] Next, a case where electricity flows from V phase wire 12 to W phase wire 13 will be described. The electricity coming in through V-phase wire 12 branches into two. One flow goes from the V-phase one end connector 221 → the V-phase third conductive pipe 123 → the V-phase other end second connector 2222 → the V-phase fourth conductive pipe 124 → the neutral wire connector 240 → the W-phase fourth conductive pipe 134 → the W-phase other end second connector 2322 → the W-phase third conductive pipe 133 → the W-phase one end connector 231 → the W-phase wire 13.

[0155] The other flow passes through the V-phase first conductive pipe 121 → the V-phase other end side first connector 2221 → the V-phase second conductive pipe 122 → the neutral wire connector 240, and then branches into two. One flows from the W-phase second conductive pipe 132 → the W-phase other end side first connector 2321 → the W-phase first conductive pipe 131 → the W-phase wire 13 . The other current flows from the W-phase fourth conductive tube 134 → the W-phase other end second connector 2322 → the W-phase third conductive tube 133 → the W-phase one end connector 231 → the W-phase wire 13 .

[0156] Figure 29 is a diagram for explaining the flow of electricity from the W-phase wire to the U-phase wire in the model development diagram shown in Figure 27. Note that the arrows indicate the direction of electricity flow.

[0157] Next, a case where electricity flows from W phase wire 13 to U phase wire 11 will be described. The electricity coming in through W phase wire 13 branches into two. One flow goes from the W-phase one end connector 231 → the W-phase third conductive tube 133 → the W-phase other end second connector 2322 → the W-phase fourth conductive tube 134 → the neutral wire connector 240 → the U-phase second conductive tube 112 → the U-phase other end first connector 2121 → the U-phase first conductive tube 111 → the U-phase wire 11.

[0158] The other flow passes through the W-phase first conductive pipe 131, the W-phase other end side first connector 2321, the W-phase second conductive pipe 132, and the neutral wire connector 240, and then branches into two. One current flows from the U-phase second conductive tube 112 → the U-phase other end side first connector 2121 → the U-phase first conductive tube 111 → the U-phase wire 11 . The other current flows from the U-phase fourth conductor tube 114 → the U-phase other end second connector 2122 → the U-phase third conductor tube 113 → the U-phase one end connector 211 → the U-phase wire 11 .

[0159] The fifth embodiment described above also has excellent cooling performance since the heat medium flows inside each conductive tube.

[0160] For the same current value, the type of this fifth embodiment (parallel connection type) generates 1 / 4 the amount of heat compared to the series connection type like the first embodiment. For the same voltage and output, the parallel connection type has twice the rotation speed compared to the series connection type, so to achieve the same rotation speed, the motor length must be doubled, and the actual amount of heat generated is about 1 / 2. If a rotation speed twice as high as the series connection type is acceptable, the amount of heat generated is 1 / 4 for the same voltage, output, and motor length. In this way, the amount of heat generated can be kept low. Conversely, this can also be said to mean that for the same motor size and weight, the rotation speed is doubled, but twice the current can be passed through.

[0289] Figure 49 is a diagram for explaining the flow of electricity from the W-phase wire to the U-phase wire in the model development diagram shown in Figure 46. Note that the arrows indicate the direction of electricity flow. Next, the flow of electricity from the W phase wire to the U phase wire will be described. The electricity entering through the W-phase wire 13 flows in the following order: W-phase wire 13 → W-phase first conductor tube 131 → W-phase other end first connector 2321 → W-phase second conductor tube 132 → W-phase one end connector 231 → W-phase third conductor tube 133 → W-phase other end second connector 2322 → W-phase fourth conductor tube 134 → neutral wire connector 240 → U-phase fourth conductor tube 114 → U-phase other end second connector 2122 → U-phase third conductor tube 113 → U-phase one end connector 211 → U-phase second conductor tube 112 → U-phase other end first connector 2121 → U-phase first conductor tube 111 → U-phase wire 11.

[0290] By configuring as in this embodiment described above, even in a 2-turn, 6N2P type rotating electrical machine, the heat medium can flow inside each conductive tube, resulting in excellent cooling performance.

[0291] In addition, by making it a two-turn type, it is possible to increase the output.

[0292] In the description of this embodiment, a two-turn type has been described to avoid complicating the explanation, but it is also possible to make it a three-turn type or a type with more turns by increasing the number of conductive tubes placed in the space (slot) between the teeth.

[0293] Eleventh embodiment FIG. 50 is a development view in which the rotating electric machine of the eleventh embodiment is modeled.

[0294] The rotating electric machine of the eleventh embodiment is a 3N2P type rotating electric machine in which a conductive tube is placed in the space (slot) between three teeth and a two-pole rotor is used. Also, while the eighth embodiment is a one-turn type in which electricity makes only one revolution around the teeth, the eleventh embodiment is a two-turn type in which electricity makes two revolutions around the teeth.

[0295] A plurality of teeth are provided protruding from the inner peripheral wall of the base portion of the stator core 20. As shown in Fig. 50, from the left, there are a first tooth 2001, a second tooth 2002, and a third tooth 2003.

Note that in Fig. 50, the U-phase second conductive tube 112 and the U-phase fourth conductive tube 114 are arranged on the first teeth 2001 side, and the V-phase first conductive tube 121 and the V-phase third conductive tube 123 are arranged on the second teeth 2002 side, but conversely, the V-phase first conductive tube 121 and the V-phase third conductive tube 123 may be arranged on the first teeth 2001 side, and the U-phase second conductive tube 112 and the U-phase fourth conductive tube 114 may be arranged on the second teeth 2002 side. However, from the standpoint of efficiency, it is desirable to arrange the U-phase second conductor tube 112 and the U-phase fourth conductor tube 114 on the first teeth 2001 side, and the V-phase first conductor tube 121 and the V-phase third conductor tube 123 on the second teeth 2002 side, as shown in Fig. 50.

[0312] (Flow of heat transfer medium) In FIG. 50, the arrows indicate the direction of heat transfer medium flow.

[0313] Next, the flow of electricity will be described. Figure 51 is a diagram for explaining the flow of electricity from the U phase wire to the V phase wire in the model development diagram shown in Figure 50. Note that the arrows indicate the direction of electricity flow. First, the flow of electricity from the U phase wire to the V phase wire will be described. The electricity entering through the U-phase wire 11 flows in the following order: U-phase wire 11 → U-phase first conductor tube 111 → U-phase other end first connector 2121 → U-phase second conductor tube 112 → U-phase one end connector 211 → U-phase third conductor tube 113 → U-phase other end second connector 2122 → U-phase fourth conductor tube 114 → neutral wire connector 240 → V-phase fourth conductor tube 124 → V-phase other end second connector 2222 → V-phase third conductor tube 123 → V-phase one end connector 221 → V-phase second conductor tube 122 → V-phase other end first connector 2221 → V-phase first conductor tube 121 → V-phase wire 12.

[0314] Figure 52 is a diagram for explaining the flow of electricity from the V-phase wire to the W-phase wire in the model development diagram shown in Figure 50. Note that the arrows indicate the direction of electricity flow. Next, the flow of electricity from the V-phase wire to the W-phase wire will be described. The electricity entering through the V-phase wire 12 flows in the following order: V-phase wire 12 → V-phase first conductor tube 121 → V-phase other end first connector 2221 → V-phase second conductor tube 122 → V-phase one end connector 221 → V-phase third conductor tube 123 → V-phase other end second connector 2222 → V-phase fourth conductor tube 124 → neutral wire connector 240 → W-phase fourth conductor tube 134 → W-phase other end second connector 2322 → W-phase third conductor tube 133 → W-phase one end connector 231 → W-phase second conductor tube 132 → W-phase other end first connector 2321 → W-phase first conductor tube 131 → W-phase wire 13.

[0315] Figure 53 is a diagram for explaining the flow of electricity from the W-phase wire to the U-phase wire in the model development diagram shown in Figure 50. Note that the arrows indicate the direction of electricity flow. Next, the flow of electricity from the W phase wire to the U phase wire will be described. The electricity coming in from phase 13 is The current flows as follows: W-phase wire 13 → W-phase first conductor tube 131 → W-phase other end first connector 2321 → W-phase second conductor tube 132 → W-phase one end connector 231 → W-phase third conductor tube 133 → W-phase other end second connector 2322 → W-phase fourth conductor tube 134 → neutral wire connector 240 → U-phase fourth conductor tube 114 → U-phase other end second connector 2122 → U-phase third conductor tube 113 → U-phase one end connector 211 → U-phase second conductor tube 112 → U-phase other end first connector 2121 → U-phase first conductor tube 111 → U-phase wire 11.

[0316] By configuring as in this embodiment described above, even in a 2-turn, 3N2P type rotating electrical machine, the heat medium can flow inside each conductive tube, resulting in excellent cooling performance.

[0317] In addition, by making it a two-turn type, it is possible to increase the output.

[0318] In the description of this embodiment, a two-turn type has been described to avoid complicating the explanation, but it is also possible to make it a three-turn type or a type with more turns by increasing the number of conductive tubes placed in the space (slot) between the teeth.

[0319] Although the embodiments of the present invention have been described above, the above-mentioned embodiments merely show some of the application examples of the present invention, and it is not intended that the technical scope of the present invention be limited to the specific configurations of the above-mentioned embodiments.

[0320] For example, in each of the above embodiments, the stator core is cylindrical, has a plurality of teeth protruding from the inner peripheral wall of the base portion, and has a structure in which a conductive tube is disposed in a space (slot) between the teeth. However, the stator core may be flat instead of cylindrical. A plurality of teeth may be protruded from the bottom surface of the base portion, and conductive tubes may be disposed in the spaces (slots) between the teeth. In this way, the present invention can be applied to a linear motor.

[0321] Furthermore, in each of the above embodiments, a plurality of teeth are provided in a protruding manner from the base portion of the stator core, and the conductive tube is disposed in the space (slot) between the teeth. However, as described in JP 2002-101591 A, a slotless type rotating electric machine (electrical energy mechanical energy converter) is known in which an air-core coil is disposed on the inner peripheral surface of a stator core that has no teeth or slots.

[0322] An example of such a stator for a rotating electric machine is shown in FIG. FIG. 54 is a perspective view showing a stator of a slotless type rotating electrical machine, with a portion of the stator core cut away.

[0323] The stator 2 of a slotless type rotating electric machine is an example of a configuration in which the coil 23 arranged inside the stator core 21 via an insulating sheet 201 is held and fixed by an even further inner protective layer 202. In FIG. 54, the coil 23 is wound only once to avoid cluttering the drawing, but in reality it is wound multiple times as necessary. Also, the insulating sheet and protective layer can be replaced by other means as appropriate, or a structure in which they are not used is also possible. A slotless type rotating electric machine can reduce cogging torque, magnet loss, iron loss, stray loss, etc.

[0324] The electric energy-mechanical energy converter (rotating electric machine / linear motor) of the present invention may be of such a slotless / coreless type.

[0325] Furthermore, in each of the above embodiments, the heat medium flow member has a two-piece structure of a main body and a lid, but the main body may also serve as the motor housing. For example, in the third embodiment, the heat medium flow member 310 has a two-piece structure of a cover (main body) 311 and a bottom plate (lid) 312. However, as shown in Fig. 55, the cover (main body) 311 may also serve as the motor housing, and may be bolted as shown in Fig. 56.

[0326] Furthermore, in each of the above embodiments, the conductive tube 100 has been described as having a flat shape, but as shown in FIG. 57, it may have a cylindrical shape.

[0327] Furthermore, the type of rotating electric machine is not limited, and the present invention can be applied to, for example, an axial flux type rotating electric machine, an SR rotating electric machine, an induction rotating electric machine, a synchronous rotating electric machine, and the like. For example, by using liquid nitrogen or liquid helium as the heat transfer medium, a superconducting rotating electric machine can be created.

[0328] The heat transfer medium to be used may be, of course, an insulating heat transfer medium or a gas such as air, but may also be antifreeze, liquefied fluorocarbons and halons, liquefied hydrocarbons, silicone oils, liquefied ammonia, liquefied nitrogen, liquefied hydrogen, liquefied rare gases, liquefied carbon dioxide, etc. For heat transfer mediums such as water, pure water with very low conductivity may be used, and additives such as corrosion inhibitors may be mixed in as appropriate.

[0329] Furthermore, by coating the inside of the conductive tube with an insulating film, it becomes possible to use a conductive heat medium, such as a water-based liquid.

[0330] By using a cryogenic heat transfer medium such as liquid nitrogen or liquid helium as the heat transfer medium and using a superconducting material for the conductive tube, a superconducting rotating electric machine can be made.

[0331] Furthermore, an ion exchange resin filter may be installed on the heat medium path, which can remove ions from the heat medium, reduce the electric conductivity of the heat medium, and increase the insulation, thereby minimizing electrical leakage in the unlikely event that a conductive heat medium leaks.

[0332] As a method for supplying the heat medium, in addition to a method that uses power such as a pump to circulate the heat medium for cooling, a natural circulation method that uses gravity without using a pump, such as a heat pipe, may be used.

[0333] There are various winding methods for motors, including concentrated winding, distributed winding, single layer winding, two layer winding, full pitch winding, short pitch winding, lap winding, concentric winding and wave winding, and an appropriate combination of these methods is selected at the time of design.

[0334] It is also possible to manufacture a type in which the stator slot teeth are closed (without the coil end heat transfer medium flow path connection parts).

[0335] In addition, while a solid type connector is given as an example in FIG. 3, it may be a hollow type in which a flow path is formed so that the heat transfer medium flows from the tip through the inside to the other end.

[0336] Furthermore, cooling from outside the stator core can also be performed as appropriate.

[0337] The above embodiments can be combined as appropriate. For example, the heat medium flow member 310 and the heat medium flow member 320 used in the second embodiment may be applied to the fifth embodiment. In this case, the result is as shown in FIG.

[0338] Moreover, when the heat medium flow member used in the fourth embodiment is applied to the third embodiment, it becomes as shown in FIG.

[0339] In this way, the above embodiments can be combined as appropriate. [Explanation of symbols]
