Its rotor has no cage winding, but is provided with reaction slots corresponding to the number of stator poles, and only plays the role of the salient pole part, without an excitation winding and a permanent magnet, and is used to generate a reluctance synchronous torque.

[0003] During the use of the reluctance synchronous motor, since it mainly acts on the internal rotor through the magnetic field, with the increase of the use time, the internal temperature of the motor gradually rises, resulting in the gradual reduction of the performance of internal components such as the iron core. Based on this, in order to further improve the heat dissipation effect of the synchronous reluctance motor, a synchronous reluctance motor provided with a water cooling device is provided.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a synchronous reluctance motor provided with a water cooling device includes a motor housing 1, and the motor housing 1 is composed of an inner housing 101, a docking cylinder column 102, a partition sheet 103, and an outer housing 104. The docking cylinder columns 102 are symmetrically fixed at both ends of the inner housing 101. A plurality of partition sheets 103 are provided, and the plurality of partition sheets 103 are circumferentially distributed and fixed on the outer side of the inner housing 101. The outer housing 104 is fixed on the outer side of the plurality of partition sheets 103. The plurality of heat dissipation cavities formed by the inner housing 101, the partition sheets 103, and the outer housing 104 are used for the flow of cooling water, so as to realize the heat dissipation operation of the heat inside the inner housing 101;

[0027] Sealing assemblies 2 are provided at both ends of the inner housing 101. The sealing assemblies 2 are used to seal both ends of the outer housing 104 and at the same time provide channels for the entry and exit of cooling water;

[0028] The sealing assembly 2 includes a sealing cover 201, an inner socket cylinder 202, an outer socket cylinder 203, an arc-shaped docking block 204, and a connecting pipe head 208;

[0029] The inner sleeve cylinder 202 is fixed to the inner end of the sealing cover 201. The outer sleeve cylinder 203 and the arc-shaped docking block 204 are fixed to the edge end face of the sealing cover 201. There are multiple arc-shaped docking blocks 204, and the multiple arc-shaped docking blocks 204 are circumferentially distributed and located inside the outer sleeve cylinder 203.

[0030] The inner sleeve cylinder 202 is used for sleeving outside the docking cylinder column 102. The outer sleeve cylinder 203 and the arc-shaped docking block 204 are respectively sleeved outside and inside the outer housing 104, so as to realize the sealing of the two ends of the outer housing 104 by the sealing cover 201.

[0031] The connecting pipe head 208 is fixed to the outside of the sealing cover 201 and penetrates to the inside of the sealing cover 201. The annular space between the outside of the inner sleeve cylinder 202 and the sealing cover 201 is communicated with the heat dissipation cavity and the connecting pipe head 208, so as to provide a channel for the circulating flow of the cooling water.

[0032] In this embodiment, it should be supplemented and explained that: a central hole for the synchronous reluctance motor shaft to penetrate is provided in the middle of the sealing cover 201.

[0033] During the operation of this synchronous reluctance motor, the two connecting pipe heads 208 can be connected to the input and output ends of the external cooling water circulation system. The external cooling water circulation system transports the cooling water into the inside of a sealing cover 201 through one connecting pipe head 208. After the cooling water enters the space between the inner side of the sealing cover 201 and the outside of the inner sleeve cylinder 202, it then enters the inside of multiple heat dissipation cavities and flows along the heat dissipation cavities to the inside of another sealing cover 201, and finally is transported to the input end of the external cooling water circulation system through the other connecting pipe head 208. During this process, the cooling water located inside the heat dissipation cavity can absorb the heat inside the inner housing 101, so as to achieve the effect of efficient heat dissipation.

[0034] Please refer specifically to Figures 2 to 4 , the sealing component 2 further includes a sealing rubber sleeve 205, a conical sealing piece 206, and a sealing rubber ring 207.

[0035] The sealing rubber sleeve 205 is sleeved outside the docking cylinder column 102, and the conical sealing piece 206 is integrally formed on the outside of the sealing rubber sleeve 205, so as to realize the sealing between the inner side of the inner sleeve cylinder 202 and the outside of the docking cylinder column 102.

[0036] The sealing rubber ring 207 is clamped between the outer sleeve cylinder 203 and the arc-shaped docking block 204, so as to realize the sealing between the end face of the outer housing 104 and the end face of the sealing cover 201.

[0037] In this embodiment: Through this structure, a good sealing performance can be maintained between the sealing cover 201, the docking cylinder column 102, and the outer housing 104, thereby ensuring the sealing of the cooling water delivery channel and preventing water seepage.

[0038] Please refer specifically to Figures 1 to 4 , a plurality of annularly distributed heat dissipation fins 105 and a wire box 106 are fixedly connected to the outer side of the outer housing 104. The wire box 106 penetrates through the outer housing 104 and is fixedly connected to the inner housing 101. The wire box 106 has two heat dissipation cavities in contact, and the width of the contact position between the wire box 106 and the heat dissipation cavity is smaller than the width of the heat dissipation cavity.

[0039] In this embodiment: Through the heat dissipation fins 105, the outer housing 104 can have a certain self-cooling function. In addition, the wire box 106 will not block the heat dissipation cavity, thereby ensuring the smooth flow of the cooling water.

[0040] Please refer specifically to Figures 1 to 4 , a plurality of annularly distributed first mounting blocks 107 are fixedly connected to both ends of the outer side of the outer housing 104, and a plurality of annularly distributed second mounting blocks 209 are fixedly connected to the outer side of the sealing cover 201. The number of the second mounting blocks 209 is half of the number of the first mounting blocks 107;

[0041] The gap width between two adjacent arc-shaped docking blocks 204 matches the thickness of the partition piece 103.

[0042] In this embodiment: It should be added that the first mounting blocks 107 and the partition piece 103 are arranged in a circumferentially staggered manner. Therefore, by clamping the arc-shaped docking blocks 204 with the partition piece 103, the alignment operation of the second mounting blocks 209 and the first mounting blocks 107 can be achieved. Corresponding through holes and threaded holes are respectively formed on the second mounting blocks 209 and the first mounting blocks 107. By passing a bolt through the through hole on the second mounting block 209 and threadedly connecting it with the threaded hole on the first mounting block 107, the installation and fixation of the sealing cover 201 can be realized;

[0043] Due to the structure that the number of the second mounting blocks 209 is half of the number of the first mounting blocks 107, after the sealing cover 201 is installed, there are still redundant first mounting blocks 107, providing a connection position for the subsequent tail dust cover. One end of the rotating shaft of the synchronous reluctance motor can extend into the tail dust cover and be connected with a cooling fan to achieve air-cooled heat dissipation.

[0044] Please refer specifically to Figures 1 to 4, the inner housing 101, the docking cylinder column 102, the partition piece 103, the outer housing 104, the heat sink 105, the wire box 106, and the first mounting block 107 are integrally formed by the casting process. The plugging cover 201, the inner socket cylinder 202, the outer socket cylinder 203, the arc-shaped docking block 204, the connecting pipe head 208, and the second mounting block 209 are integrally formed by the casting process.

[0045] In this embodiment: When the synchronous reluctance motor is produced and processed, the motor housing 1 and the plugging cover 201 are respectively formed by the casting process, and then assembled, which is convenient for popularization and production.

[0046] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
