Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] Embodiments of the vehicle of the invention, such as Figure 1 to Figure 8 As shown, the vehicle includes a frame and a motor arranged on the frame. The motor includes a base 1 with an inner cavity and a stator assembly 2 in the inner cavity of the base 1. The outer circumference of the stator assembly 2 is distributed along the circumferential interval. Its axially extending limiting groove 21, the inner peripheral surface of the machine base 1 is circ...

Abstract

The invention relates to an electric motor and a vehicle using the same. The stator assembly and the frame in the electric machine of the invention are connected through the cooperation of the limiting protrusion and the limiting groove, so that the stresses between the stator assembly and the frame are relatively evenly distributed, which ensures the reliability of the connection between the stator assembly and the limit slot, At the same time, the cooperation of the limiting protrusion and the limiting groove enlarges the contact area between the machine frame and the stator assembly, ensures that the heat on the stator assembly can be efficiently transferred to the fluid in the fluid channel, and improves the heat dissipation efficiency. Therefore, the motor not only has stable structure, but also has high heat dissipation efficiency, and improves the performance of the motor.

Description

technical field [0001] The invention relates to a motor and a vehicle using the motor. Background technique [0002] At present, various motors are used in the field of motors, including permanent magnet synchronous motors and asynchronous motors. The stator components used in these motors are basically regular barrel-shaped structures, and the cooperation between the stator components and the frame is only at the shaft end of the stator. In the position, in the process of long-term rotation operation, it is easy to have uneven stress. [0003] In the prior art, the Chinese patent document whose authorization notification number is CN206908396U discloses a stator core assembly structure of an AC motor. The outer circumference of the iron core of the motor is provided with a plurality of iron core keyways extending along its axial direction, while the inner surface of the frame is There is a machine base keyway corresponding to the keyway on the peripheral surface. The posit...
