[0002] The present invention relates to the technical field of motors, and in particular to a winding, a disc-type stator and a disc-type motor. Background Art

[0003] To improve the cooling efficiency of disc motors, chokes are typically placed between adjacent stator cores to adjust the flow path of the motor's coolant. However, because the stator cores are surrounded by windings, particularly the bridge wires of the windings, they interfere with the placement of the chokes, preventing the coolant from flowing along the desired path and impacting the motor's cooling efficiency.

[0004] Therefore, how to reduce the interference between the winding and the baffle and improve the cooling effect of the disc motor is a technical problem that those skilled in the art currently face.

[0046] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to explain the relevant invention and are not intended to limit the invention. The embodiments described are merely some embodiments of the present invention, not all embodiments. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0047] Referring to FIG1 , FIG1 shows a schematic structural diagram of a disc motor.

[0048] The illustrated disc motor includes a disc stator, a housing 300, and a baffle 400. The disc stator and baffle 400 are both disposed within the housing 300. The baffle 400 is arranged between the disc stator and the housing 300 in a regular pattern to alter the coolant flow trajectory in the disc motor and extend the contact time between the coolant and the disc stator.

[0049] The disc stator is located inside the housing 300, with the disc stator as the boundary. The housing 300 corresponds to the outer side of the disc stator as the outer shell wall 300a, and the housing 300 corresponds to the inner side of the disc stator as the inner shell wall 300b. The outer flow channel is formed between the disc stator and the outer shell wall 300a, and the inner flow channel is formed between the disc stator and the inner shell wall 300b.

[0050] The baffle blocks 400 may include an outer baffle block 410, an inner baffle block 420, and / or a full baffle block 430. The outer baffle block 410 is arranged between the outer shell wall 300a and the disc stator to block the outer flow channel, the inner baffle block 420 is arranged between the inner shell wall 300b and the disc stator to block the inner flow channel, and the full baffle block 430 is arranged between the outer shell wall 300a and the inner shell wall 300b and passes through adjacent stator cores 200 of the disc stator to block both the outer and inner flow channels.

[0051] In the figure, outer baffles 410 and inner baffles 420 are arranged alternately in a counterclockwise direction, with a full baffle 430 arranged at the end, dividing the chambers within the housing 300 into a first chamber 310, a second chamber 320, a third chamber 330, a fourth chamber 340, a fifth chamber 350, a sixth chamber 360, and a seventh chamber 370. The liquid inlet of the housing 300 is connected to the first chamber 310, and the liquid outlet of the housing 300 is connected to the seventh chamber 370. Coolant enters the disc motor through the liquid inlet and flows through the first chamber 310, the second chamber 320, the third chamber 330, the fourth chamber 340, the fifth chamber 350, the sixth chamber 360, and the seventh chamber 370 in sequence, before flowing out through the liquid outlet.

[0052] The number and arrangement of the baffles 400 can be adjusted as needed.

[0053] Referring to FIG. 2 , FIG. 2 shows a schematic diagram of a disc-type stator core.

[0054] The disc-type stator core includes a plurality of stator cores 200 arranged in a circular ring structure. The figure shows twenty-four stator cores 200. However, the illustrated number of stator cores 200 is merely an example. In the embodiment of the present invention, the number of stator cores 200 may also be other numbers, which will not be described in detail in this invention.

[0055] In counterclockwise direction, they are the first stator core 201, the second stator core 202, the third stator core 203, the fourth stator core 204, the fifth stator core 205, the sixth stator core 206, the seventh stator core 207, the eighth stator core 208, the ninth stator core 209, the tenth stator core 210, the eleventh stator core 211, the twelfth stator core 212, the thirteenth stator core 213, the fourteenth stator core 214, the fifteenth stator core 215, the sixteenth stator core 216, the seventeenth stator core 217, the eighteenth stator core 218, the nineteenth stator core 219, the twentieth stator core 220, the twentieth stator core 221, the twenty-second stator core 222, the twenty-third stator core 223, and the twenty-fourth stator core 224.

[0056] To improve the cooling efficiency of disc motors, flow blocks are typically placed between adjacent stator cores to adjust the flow path of the motor's coolant. Since windings 100 are wound around the outer circumference of the stator cores, the bridge wires of windings 100 can interfere with the placement of flow blocks 400, preventing the coolant from flowing completely along the adjusted flow path and thus affecting the cooling efficiency of the disc motor.

[0057] To solve the above technical problems, the embodiment of the present invention changes the structure of the winding 100 so that the baffles 400 can be arranged between adjacent stator cores 200 in the disc-type stator, while also meeting the arrangement requirements of the winding 100. Detailed description is given below with reference to the accompanying drawings.

[0058] Referring to FIG. 3 , FIG. 3 shows a schematic structural diagram of a winding 100 .

[0059] The winding 100 shown in the figure includes multiple half turns for winding around the outer circumference of the stator core 200, multiple inner bridge wires and multiple outer bridge wires. Adjacent half turns are connected by inner bridge wires or outer bridge wires; the inner bridge wires connect the proximal ends 200a of the half turns, and the outer bridge wires connect the distal ends 200b of the half turns.

[0060] There are eight half turns in the figure, which are, in counterclockwise direction, a first half turn 111 , a second half turn 112 , a third half turn 113 , a fourth half turn 114 , a fifth half turn 115 , a sixth half turn 116 , a seventh half turn 117 and an eighth half turn 118 .

[0061] There are four inner bridge wires, which are, in counterclockwise order, a first inner bridge wire 121 , a second inner bridge wire 122 , a third inner bridge wire 123 and a fourth inner bridge wire 124 .

[0062] There are three outer bridge lines, which are, in counterclockwise order, a first outer bridge line 131 , a second outer bridge line 132 and a third outer bridge line 133 .

[0063] Specifically, the winding 100 is wound in a counterclockwise direction, sequentially including a first half turn 111, a first inner bridge wire 121, a second half turn 112, a first outer bridge wire 131, a third half turn 113, a second inner bridge wire 122, a fourth half turn 114, a second outer bridge wire 132, a fifth half turn 115, a third inner bridge wire 123, a sixth half turn 116, a third outer bridge wire 133, a seventh half turn 117, a fourth inner bridge wire 124, and an eighth half turn 118.

[0064] The winding 100 is wound in a counterclockwise direction as a whole, and each half turn is wound in a clockwise direction.

[0065] It should be noted that the number of the above-mentioned half turns, inner bridge wires and outer bridge wires can be adjusted as needed.

[0066] In the embodiment of the present invention, a half-turn can be understood as a structure wound in the manner of half-turn winding. Referring to FIG4 , the figure takes the first half-turn 111 wound on the outer periphery of the stator core 200 as an example. The stator core 200 in the figure is only used as an example of a cubic structure, which does not mean that the actual structure of the stator core 200 is like this. It is intended to reflect that the stator core 200 has length, thickness and width, wherein the length corresponds to the first direction, the thickness corresponds to the second direction, and the width corresponds to the third direction, and the first direction, the second direction and the third direction are perpendicular to each other. The stator core 200 is installed in a disc motor, and the length of the stator core 200 coincides with the radial direction of the disc motor, and the thickness of the stator core 200 coincides with the axial direction of the disc motor. For ease of understanding, in the embodiment of the present invention, the stator core 200 defines a proximal end 200a and a distal end 200b in the length direction, wherein the proximal end 200a is arranged closer to the axis of the disc motor than the distal end 200b, and the distal end 200b is arranged farther away from the axis of the disc motor than the distal end 200b.

[0067] The first half-turn 111 is wound around the outer circumference of the stator core 200 in a half-turn winding manner. Specifically, the winding 100 is wound around the outer circumference of the stator core 200 in a clockwise direction from bottom to top, and the incoming end 111a and the outgoing end 111b of the winding 100 are both located on the same side of a line connecting the center of the proximal end 200a and the center of the distal end 200b. Of course, in some embodiments of the present invention, the winding 100 can also be wound around the outer circumference of the stator core 200 in a clockwise direction from top to bottom.

[0068] In combination with FIG. 2 and FIG. 3 , refer to FIG. 5 , which shows a schematic diagram of a disc-type stator.

[0069] The disc stator includes a disc stator core and a winding 100 , wherein the disc stator core is the disc stator core shown in FIG. 2 , and the winding 100 is the winding 100 described in FIG. 3 .

[0070] The winding 100 has three phases, namely, an A-phase winding 100a, a B-phase winding 100b, and a C-phase winding 100c. The A-phase winding 100a, the B-phase winding 100b, and the C-phase winding 100c have the same structure except for the winding stator core 200.

[0071] In the A-phase winding 100a, the first half turn 111 is wound on the first stator core 201, the second half turn 112 is wound on the fourth stator core 204, the third half turn 113 is wound on the seventh stator core 207, the fourth half turn 114 is wound on the eleventh stator core 211, the fifth half turn 115 is wound on the thirteenth stator core 213, the sixth half turn 116 is wound on the sixteenth stator core 216, the seventh half turn 117 is wound on the nineteenth stator core 219, and the eighth half turn 118 is wound on the twenty-second stator core 222.

[0072] In the B-phase winding 100b, the first half turn 111 is wound on the second stator core 202, the second half turn 112 is wound on the fifth stator core 205, the third half turn 113 is wound on the eighth stator core 208, the fourth half turn 114 is wound on the twelfth stator core 212, the fifth half turn 115 is wound on the fourteenth stator core 214, the sixth half turn 116 is wound on the seventeenth stator core 217, the seventh half turn 117 is wound on the twentieth stator core 220, and the eighth half turn 118 is wound on the twenty-third stator core 223.

[0073] In the C-phase winding 100 c, the first half turn 111 is wound on the third stator core 203 , the second half turn 112 is wound on the sixth stator core 206 , the third half turn 113 is wound on the ninth stator core 209 , the fourth half turn 114 is wound on the thirteenth stator core 213 , the fifth half turn 115 is wound on the fifteenth stator core 215 , the sixth half turn 116 is wound on the eighteenth stator core 218 , the seventh half turn 117 is wound on the twenty-first stator core 221 , and the eighth half turn 118 is wound on the twenty-fourth stator core 224 .

[0074] It can be seen that in the embodiment of the present invention, the A-phase winding 100a, the B-phase winding 100b, and the C-phase winding 100c are staggered and wound counterclockwise on the corresponding stator core 200. Furthermore, the inner bridge wires in the A-phase winding 100a, the B-phase winding 100b, and the C-phase winding 100c are all located near the center end of the stator core 200, while the outer bridge wires in the A-phase winding 100a, the B-phase winding 100b, and the C-phase winding 100c are all located far from the center end of the stator core 200.

[0075] It is explained here that in the disc stator, multiple stator cores 200 form a circular structure. Since each stator core 200 has a proximal end 200a close to the axis of the disc stator and a distal end 200b away from the axis of the disc stator, the side where the proximal ends 200a of all stator cores 200 are located can be understood as the proximal end side (which can also be understood as the inner side of the disc stator), and the side where the distal ends 200b of all stator cores 200 are located can be understood as the distal end side (which can also be understood as the outer side of the disc stator).

[0076] Referring to FIG. 6 , FIG. 6 shows a schematic structural diagram of a disc motor based on the disc stator shown in FIG. 5 .

[0077] The illustrated disc motor includes a disc stator, a housing 300, and a baffle 400. The disc stator and baffle 400 are both disposed within the housing 300. The baffle 400 is arranged between the disc stator and the housing 300 in a regular pattern to alter the coolant flow trajectory in the disc motor and extend the contact time between the coolant and the disc stator.

[0078] The disc stator shown in the figure is the disc stator described in FIG5 , and will not be described in detail here.

[0079] In the embodiment of the present invention, the spoiler 400 includes a first outer spoiler 411, a first inner spoiler 421, a second outer spoiler 412, a second inner spoiler 422, a third outer spoiler 413, a third inner spoiler 423, a fourth outer spoiler 414 and a first full spoiler 431, which are arranged in a counterclockwise direction. The outer flow channel and the inner flow channel of the spoiler 400 housing 300 are separated into a first cavity 310, a second cavity 320, a third cavity 330, a fourth cavity 340 and a fourth cavity 350, which are connected in sequence. The first cavity 310 is connected to the liquid inlet, and the ninth cavity 390 is connected to the liquid outlet; wherein the first cavity 310, the third cavity 330, the fifth cavity 350, the seventh cavity 370 and the ninth cavity 390 are formed in the outer flow channel; the second cavity 320, the fourth cavity 340, the sixth cavity 360 and the eighth cavity 380 are formed in the inner flow channel.

[0080] The coolant enters the first cavity 310 from the liquid inlet, and passes through the second cavity 320, the third cavity 330, the fourth cavity 340, the fifth cavity 350, the sixth cavity 360, the seventh cavity 370, the eighth cavity 380 and the ninth cavity 390 in sequence and flows out from the liquid outlet, forming a cooling circulation path.

[0081] It should be noted that the first cavity 310 is the cavity located at the head end of the above-mentioned cavity, which is connected to the liquid inlet of the shell 300, and the ninth cavity 390 is the cavity located at the end of the above-mentioned cavity, which is connected to the liquid outlet of the shell 300.

[0082] The first external choke 411 is located between the stator core 200 and the first inner bridge wire 121 of the A-phase winding 100 a , the first inner bridge wire 121 of the B-phase winding 100 b , and the first inner bridge wire 121 of the C-phase winding 100 c , thereby avoiding the windings 100 .

[0083] The second outer choke 412 is located between the stator core 200 and the second inner bridge wire 122 of the A-phase winding 100 a , the second inner bridge wire 122 of the B-phase winding 100 b , and the second inner bridge wire 122 of the C-phase winding 100 c , thereby avoiding the windings 100 .

[0084] The third outer choke 413 is located between the stator core 200 and the third inner bridge wire 123 of the A-phase winding 100 a , the third inner bridge wire 123 of the B-phase winding 100 b , and the third inner bridge wire 123 of the C-phase winding 100 c , thereby avoiding the windings 100 .

[0085] The fourth outer choke 414 is located between the stator core 200 and the fourth inner bridge wire 124 of the A-phase winding 100 a , the fourth inner bridge wire 124 of the B-phase winding 100 b , and the fourth inner bridge wire 124 of the C-phase winding 100 c , thereby avoiding the windings 100 .

[0086] The first inner baffle 421 is located between the stator core 200 and the first outer bridge wires 131 of the A-phase winding 100 a , the B-phase winding 100 b , and the C-phase winding 100 c , thereby avoiding the windings 100 .

[0087] The second inner baffle 422 is located between the stator core 200 and the second outer bridge wires 132 of the A-phase winding 100 a , the B-phase winding 100 b , and the C-phase winding 100 c , thereby avoiding the windings 100 .

[0088] The third inner baffle 423 is located between the stator core 200 and the third outer bridge wire 133 of the A-phase winding 100a, the third outer bridge wire 133 of the B-phase winding 100b, and the third outer bridge wire 133 of the C-phase winding 100c, thereby avoiding the winding 100.

[0089] The first full choke block 431 is located between the stator core 200 (the first stator core 201 ) wound with the first half turn 111 of the A-phase winding 100a and the stator core 200 (the twenty-fourth stator core 224 ) wound with the eighth half turn 118 of the C-phase winding 100c.

[0090] The incoming wire ends of the A-phase winding 100a, the B-phase winding 100b and the C-phase winding 100c are located in the first cavity 310; the three neutral points 100d of the A-phase winding 100a, the B-phase winding 100b and the C-phase winding 100c are located in the fifth cavity 350.

[0091] It can be seen that in the embodiment of the present invention, the inner bridge wires are used to avoid the setting of the outer spoiler block 410, and the outer bridge wires are used to avoid the setting of the inner spoiler block 420; further, the number of the inner bridge wires is consistent with the number of the outer spoiler blocks 410, and the number of the outer bridge wires is consistent with the number of the inner spoiler blocks 420.

[0092] Furthermore, the length of the inner bridge wire at least spans over two stator cores 200 , and the length of the outer bridge wire at least spans over two stator cores 200 .

[0093] The winding 100 of the present invention includes multiple outer and inner bridge wires. The outer bridge wires can be positioned with inner baffles 420, while the inner bridge wires can be positioned with outer baffles 410. Therefore, when using the winding 100 of the present invention, the inner and outer baffles 410 can be arranged as needed, reducing interference from the winding 100 on the arrangement of the baffles 400. This makes sealing between the baffles 400 and the housing 300 easier, thereby improving the cooling effect of the disc motor.

[0094] Referring to FIG. 7 , FIG. 7 shows a schematic structural diagram of another disc motor.

[0095] The illustrated disc motor includes a disc stator, a housing 300, and a baffle 400. The disc stator and baffle 400 are both disposed within the housing 300. The baffle 400 is arranged between the disc stator and the housing 300 in a regular pattern to alter the coolant flow trajectory in the disc motor and extend the contact time between the coolant and the disc stator.

[0096] The disc stator shown in the figure is the disc stator described in FIG5 , and will not be described in detail here.

The outer flow channel and the inner flow channel of the shell 300 of the baffle 400 are divided into a first cavity 310, a second cavity 320, a third cavity 330, a fourth cavity 340, a fifth cavity 350, a sixth cavity 360 and a seventh cavity 370, which are connected in sequence. The first cavity 310 is connected to the liquid inlet, and the fifth cavity 350 is connected to the liquid outlet. The first cavity 310, the third cavity 330, the fifth cavity 350 and the seventh cavity 370 are formed in the outer flow channel; the second cavity 320, the fourth cavity 340 and the sixth cavity 360 are formed in the inner flow channel.

[0098] The coolant enters the first cavity 310 from the liquid inlet, exchanges heat with the stator core 200 at the first cavity 310, and then enters the second cavity 320. It is divided into two paths by the second cavity 320, one part of the coolant enters the third cavity 330, the fourth cavity 340 and the fifth cavity 350 in sequence to form a cooling circulation path; the other part of the coolant enters the seventh cavity 370, the sixth cavity 360 and the fifth cavity 350 in sequence to form another cooling circulation path; the two paths of coolant converge into the fifth cavity 350 and flow out from the liquid outlet.

[0099] It should be noted that the first cavity 310 is the cavity located at the head end of the above-mentioned cavity, which is connected to the liquid inlet of the shell 300, and the seventh cavity 370 is the cavity located at the end of the above-mentioned cavity. In principle, except for the above-mentioned first cavity 310 and the seventh cavity 370, other cavities can be understood as cavities located in the middle. In this example, the fifth cavity 350 is connected to the liquid outlet of the shell 300.

[0100] The disc motor shown in FIG7 is different from the disc motor shown in FIG6 in that the disc motor shown in FIG7 does not include the first full flow block 431 , which results in changes in the number and flow direction of the cooling circulation paths in the disc motor.

[0101] For the same winding 100 , the number and flow direction of the cooling circulation paths of the disc motor can be changed by changing the number and arrangement of the baffle blocks 400 Still other embodiments of the present invention can further adjust the winding structure of the winding 100 .

Furthermore, the inner bridge wires in the A-phase winding 100a, the B-phase winding 100b, and the C-phase winding 100c are all located near the center end of the stator core 200, while the outer bridge wires in the A-phase winding 100a, the B-phase winding 100b, and the C-phase winding 100c are all located far from the center end of the stator core 200.

[0126] The first full choke block 431 is located between the stator core 200 (the 24th stator core 224 ) wound with the first half turn 111 of the A-phase winding 100a and the stator core 200 (the 23rd stator core 223 ) wound with the eighth half turn 118 of the C-phase winding 100c.

[0129] Furthermore, the length of the inner bridge wire at least spans over two stator cores 200 , and the length of the outer bridge wire at least spans over two stator cores 200 .

[0130] Still other embodiments of the present invention further adjust the winding structure of the winding 100 .

[0131] Referring to FIG. 11 , FIG11 shows a schematic diagram of yet another winding 100 .

[0132] The illustrated winding 100 includes a plurality of half turns for winding around the outer circumference of the stator core 200, a plurality of inner bridge wires, a plurality of outer bridge wires, and a plurality of full turns for winding around the outer circumference of the stator core 200. The full turns and half turns are arranged at intervals, and adjacent full turns and half turns are connected by inner bridge wires or outer bridge wires; the inner bridge wires connect the proximal ends 200a of the full turns and half turns, and the outer bridge wires connect the distal ends 200b of the full turns and half turns.

[0133] The difference from the winding 100 shown in FIG3 is that the winding 100 shown in FIG8 is wound in a counterclockwise direction as a whole, and each half turn is wound in a counterclockwise direction.

[0134] In the figure, there are four half turns, which are, in counterclockwise direction, a first half turn 111 , a second half turn 112 , a third half turn 113 and a fourth half turn 114 .

[0135] There are four inner bridge wires, which are, in counterclockwise order, a first inner bridge wire 121 , a second inner bridge wire 122 , a third inner bridge wire 123 and a fourth inner bridge wire 124 .

[0137] In the figure, there are four full turns, which are, in counterclockwise direction, a first full turn 141 , a second full turn 142 , a third full turn 143 and a fourth full turn 144 .

[0138] Specifically, the winding 100 is wound in a counterclockwise direction, sequentially including a first full turn 141, a first outer bridge wire 131, a first half turn 111, a first inner bridge wire 121, a second full turn 142, a second inner bridge wire 122, a second half turn 112, a second outer bridge wire 132, a third full turn 143, a third outer bridge wire 133, a third half turn 113, a third inner bridge wire 123, a fourth full turn 144, a fourth inner bridge wire 124, and a fourth half turn 114.

[0139] The winding 100 is wound in a counterclockwise direction as a whole, and each half turn and each full turn are wound in a clockwise direction.

[0140] It should be noted that the number of the above-mentioned half turns, inner bridge wires and outer bridge wires can be adjusted as needed.

[0141] In the embodiment of the present invention, a full turn can be understood as a structure wound in a full-turn winding manner. Referring to Figure 12, the figure takes the first full turn 141 wound around the outer periphery of the stator core 200 as an example. The stator core 200 in the figure is only used as an example of a cubic structure, which does not mean that the actual structure of the stator core 200 is like this. It is intended to reflect that the stator core 200 has a length, thickness and width, wherein the length corresponds to the first direction, the thickness corresponds to the second direction, and the width corresponds to the third direction, and the first direction, the second direction and the third direction are perpendicular to each other. The stator core 200 is installed in a disc motor, and the length of the stator core 200 coincides with the radial direction of the disc motor, and the thickness of the stator core 200 coincides with the axial direction of the disc motor. For ease of understanding, in the embodiment of the present invention, the stator core 200 defines a proximal end 200a and a distal end 200b in the length direction, wherein the proximal end 200a is arranged closer to the axis of the disc motor than the distal end 200b, and the distal end 200b is arranged farther away from the axis of the disc motor than the distal end 200b.

[0142] The first full turn 141 is wound around the outer circumference of the stator core 200 in a full-turn winding manner. Specifically, the winding 100 is wound around the outer circumference of the stator core 200 in a clockwise direction from bottom to top, and the incoming end 141a and the outgoing end 141b of the winding 100 are both located on the same side of a line connecting the center of the proximal end 200a and the center of the distal end 200b. Of course, in some embodiments of the present invention, the winding 100 can also be wound around the outer circumference of the stator core 200 in a clockwise direction from top to bottom.

[0143] In combination with FIG. 2 and FIG. 11 , refer to FIG. 13 , which shows a schematic diagram of a disc-type stator.

[0144] The disc stator includes a disc stator core and a winding 100 , wherein the disc stator core is the disc stator core shown in FIG. 2 , and the winding 100 is the winding 100 described in FIG. 11 .

[0145] The winding 100 has three phases, namely, an A-phase winding 100a, a B-phase winding 100b, and a C-phase winding 100c. The A-phase winding 100a, the B-phase winding 100b, and the C-phase winding 100c have the same structure except for the winding stator core 200.

[0146] In the A-phase winding 100a, the first full turn 141 is wound on the first stator core 201, the first half turn 111 is wound on the fourth stator core 204, the second full turn 142 is wound on the seventh stator core 207, the second half turn 112 is wound on the eleventh stator core 211, the third full turn 143 is wound on the thirteenth stator core 213, the third half turn 113 is wound on the sixteenth stator core 216, the fourth full turn 144 is wound on the nineteenth stator core 219, and the fourth half turn 114 is wound on the twenty-second stator core 222.

[0147] In the B-phase winding 100 b, the first full turn 141 is wound on the second stator core 202, the first half turn 111 is wound on the fifth stator core 205, the second full turn 142 is wound on the eighth stator core 208, the second half turn 112 is wound on the twelfth stator core 212, the third full turn 143 is wound on the fourteenth stator core 214, the third half turn 113 is wound on the seventeenth stator core 217, the fourth full turn 144 is wound on the twentieth stator core 220, and the fourth half turn 114 is wound on the twenty-third stator core 223.

[0148] In the C-phase winding 100 c, the first full turn 141 is wound on the third stator core 203 , the first half turn 111 is wound on the sixth stator core 206 , the second full turn 142 is wound on the ninth stator core 209 , the second half turn 112 is wound on the thirteenth stator core 213 , the third full turn 143 is wound on the fifteenth stator core 215 , the third half turn 113 is wound on the eighteenth stator core 218 , the fourth full turn 144 is wound on the twenty-first stator core 221 , and the fourth half turn 114 is wound on the twenty-fourth stator core 224 .

[0149] It can be seen that in the embodiment of the present invention, the A-phase winding 100a, the B-phase winding 100b, and the C-phase winding 100c are staggered and wound counterclockwise on the corresponding stator core 200. Furthermore, the inner bridge wires in the A-phase winding 100a, the B-phase winding 100b, and the C-phase winding 100c are all located near the center end of the stator core 200, while the outer bridge wires in the A-phase winding 100a, the B-phase winding 100b, and the C-phase winding 100c are all located far from the center end of the stator core 200.

[0150] It is explained here that in the disc stator, multiple stator cores 200 form a circular structure. Since each stator core 200 has a proximal end 200a close to the axis of the disc stator and a distal end 200b away from the axis of the disc stator, the side where the proximal ends 200a of all stator cores 200 are located can be understood as the proximal end side (which can also be understood as the inner side of the disc stator), and the side where the distal ends 200b of all stator cores 200 are located can be understood as the distal end side (which can also be understood as the outer side of the disc stator).

[0155] The cooling liquid enters the first cavity 310 from the liquid inlet, passes through the second cavity 320, the third cavity 330, the fourth cavity 340 and the fifth cavity 350 in sequence, and flows out from the liquid outlet, forming a cooling circulation path.

[0156] It should be noted that the first cavity 310 is the cavity located at the head end of the above-mentioned cavity, which is connected to the liquid inlet of the shell 300, and the fifth cavity 350 is the cavity located at the end of the above-mentioned cavity, which is connected to the liquid outlet of the shell 300.
