Problems solved by technology

[0004] However, due to the interference fit between the stator and the casing, in order to avoid the eccentricity of the stator, there is a very high requirement for the machining accuracy of the concave-convex structure, which causes great difficulties in machining.

Abstract

The embodiment of the invention provides a stator punching sheet, a stator iron core, a motor and a vehicle. The stator iron core comprises a yoke part, a tooth part and a first groove body. The number of the tooth parts is multiple, and the multiple tooth parts are arranged at intervals in the circumferential direction of the yoke part. The number of the first groove bodies is multiple, and each first groove body is arranged at the end, close to the tooth root, of each tooth part in the axial direction of the yoke part. According to the stator punching sheet provided by the embodiment of the invention, the radial electromagnetic force can be decomposed by using the first groove body, the transmission path of the radial electromagnetic force is optimized, and the excitation effect of the radial electromagnetic force on the stator core is weakened, so that the effects of weakening the vibration of the motor shell and reducing the noise are realized, the overall vibration and noise of the motor are favorably reduced, and the service life of the motor is prolonged. The NVH level of a vehicle is suppressed.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator punch, a stator core, a motor and a vehicle. Background technique [0002] In related technologies, NVH (Noise, Vibration, Harshness; noise, vibration and harshness) performance is one of the important indicators for evaluating the quality of automobile manufacturing. For new energy vehicles, one of the main sources of vibration and noise is the motor. During the operation of the motor, due to the generation of radial electromagnetic force, it is easy to cause the stator of the motor to vibrate under the excitation of radial electromagnetic force, which in turn causes the overall vibration and noise of the motor, which has a negative impact on the NVH performance of the vehicle. [0003] In order to weaken the vibration of the motor under the action of radial electromagnetic force, several concave-convex structures are usually arranged on the outer peripheral surface of ...
