In this embodiment, since the first colloid 500 is disposed on the inner wall of the casing 100, the first colloid 500 can fix the stator assembly 200 and the casing 100, so as to improve the connection strength between the stator assembly 200 and the casing 100, improve the stability of the stator assembly 200 and the casing 100, and reduce the vibration generated by the motor during operation. And the first colloid 500 is located between the stator assembly 200 and the housing 100, even if vibration is generated due to torque pulsation or electromagnetic force of the motor, the vibration is absorbed and weakened by the first colloid 500 when being transmitted to the housing 100 from the stator assembly 200, and the first colloid 500 in at least one colloid groove 120 is further improved, so that the vibration of the motor is further reduced.

The first colloid 500 is located between the stator assembly 200 and the housing 100, so that the vibration of the motor can be reduced, the noise caused by the vibration of the housing 100 can be reduced, and the noise of the motor can be improved.

As shown in fig. 4, for the vibration of the motor, the vibration source 610 is transmitted to the receiver 630 through the transmission path 620, so that the receiver 630 can feel the vibration of the motor, and the first colloid 500 is located between the stator assembly 200 and the housing 100, so that the first colloid 500 is located on the transmission path 620 of the motor noise, and the noise can be absorbed by the first colloid 500, thereby reducing the noise generated inside the motor, such as the electromagnetic noise of the motor, and further reducing the noise of the motor.

Further, stator module 200 includes stator core and winding, and stator core includes the stator tooth, is provided with the stator slot between the adjacent stator tooth, and the winding is around locating on the stator tooth to inlay in the stator slot. When assembling stator module 200, earlier carry out the wire winding to stator core for the winding is wound on stator tooth, then install stator module 200 in casing 100, stator core can with casing 100 interference fit, after finishing stator assembly overall assembly, carry out whole encapsulating to stator assembly and handle, in order to form first colloid 500 in gluey groove 120, and form the second colloid in stator module 200's the outside and the clearance of winding.

As shown in fig. 2 and 5, when the stator assembly is subjected to the overall glue filling process, the fixture 400 is placed in the middle of the stator core, and glue is filled between the fixture 400 and the shell 100 until the glue completely immerses the winding and the glue tank 120.

The stator assembly is subjected to overall glue filling treatment, so that the contact area of the stator assembly 200 and the first glue body 500 and the second glue body can be effectively increased, and the stability of the stator assembly during the working of the motor is further improved.

The stator core may be press-fitted to the case 100 by a press, or the case 100 may be heated, and the case 100 may be shrink-fitted on the stator core.

The second colloid fills the periphery of the bearing chamber inside the housing 100.

In an embodiment of the present invention, there is provided an electric machine, including the housing 100 according to any of the above embodiments; or a stator assembly as in any of the embodiments described above. Therefore, the motor has all the advantages of the housing 100 of any of the above embodiments or the stator assembly of any of the above embodiments.

The motor that this application provided, as shown in fig. 6, through setting up first colloid 500 and second colloid, 24 rank tangential vibration of the motor that stator module 200 is not glued and the motor that only stator module 200 is glued are obviously higher than 24 rank tangential vibration of the motor that this application provided, especially at high-speed stage, the vibration of the motor that this application provided obviously reduces. Because the motor has less vibration in the low-speed stage, the vibration in the height reducing stage has a particularly obvious effect on reducing the vibration of the motor.

The motor provided by the application is provided with the mounting parts 150, as shown in fig. 7, so that the vibration of the motor is reduced, and particularly in a high-frequency stage, the vibration of the motor with the three mounting parts 150 is smaller.

Further, the motor further includes a rotor assembly 300, the rotor assembly 300 is embedded in the stator assembly 200, and the stator assembly 200 can drive the rotor assembly 300, so as to output power.

Rotor subassembly 300 includes rotor core, permanent magnet and injection molding body, and iron core and permanent magnet adopt the arrangement of syllogic oblique utmost point structure, and the contained angle of oblique utmost point is 5.

In an embodiment of the present invention, there is provided a vehicle including the motor according to any one of the above embodiments, and therefore the vehicle has all the advantages of the motor according to any one of the above embodiments.

Further, the motor can also be used for industrial control equipment.
