In some embodiments, referring to fig. 1 and 2, the edge of the mounting hole 10a on the side away from the other mounting member 10 is an inclined tapered surface 10b, and the radial dimension of the inclined tapered surface 10b gradually increases in the direction away from the other mounting member 10. The inclined conical surface 10b enables the edge of the mounting hole 10a to avoid the winding penetrating through the stator core 40, so that more abundant mounting space is provided for mounting the winding, and meanwhile, the structural weight of the mounting piece 10 is reduced. In some embodiments, referring to fig. 3 and fig. 4, the inclined conical surface 10b is provided with a plurality of ventilation holes 10c arranged at intervals along the circumferential direction of the mounting hole 10a, the ventilation holes 10c penetrate through the mounting piece 10 along the axial direction, and air flow can pass through the ventilation holes 10c to be in contact with the stator core 41, so that heat generated by the stator core 41 in the working process is taken away, and the heat dissipation performance of the motor is improved; meanwhile, the weight of the motor is reduced.

The embodiment of the present utility model further provides a motor, referring to fig. 2, the motor includes a stator core 40 and a motor base according to any of the foregoing embodiments, where the stator core 40 is sandwiched between the mounting members 10.

The stator core 40 may be attached to the inner wall of the mounting hole 10a or may be provided at intervals.

The motor further includes a rotor disposed through the stator core 40.

In some embodiments with ventilation holes 10c, the stator core 40 is provided with ventilation channels that are penetrated in the axial direction, and two ends of each ventilation channel are respectively communicated with the ventilation holes 10c on one mounting piece 10, so that air flow can enter the stator core 40, and thus a better cooling effect is achieved.

The embodiment of the present utility model also provides a vehicle, a vehicle body and the motor of the foregoing embodiment, wherein the carrier 20 is connected to the vehicle body in a first direction, and the mount 10 is connected to the vehicle body in a second direction, so that the motor is fixed to the vehicle body.

The vehicle body is the target device.

The manner of connection of the carrier 20 to the vehicle body is not limited, for example, bolting or the like.

The manner of connection of the mount 10 to the vehicle body is not limited, and is, for example, bolting or the like.

The specific type of vehicle is not limited, such as a rail train, a new energy automobile, and the like.

The various embodiments/implementations provided herein may be combined with one another without conflict.

The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations can be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
