Abstract

The invention relates to an automobile starting motor stator core, which comprises a stator core body, wherein the stator core body has winding grooves and stator teeth, the stator teeth have virtualgrooves, the stator core body is provided with heat exchange tubes in a penetrating mode, cooling holes are formed in the stator core body in a penetrating mode, the stator core body is composed of aplurality of silicon steel sheets, and the silicon steel sheets are coated with high-temperature-resistant insulating paint layers. An automobile starting motor stator core machining process comprisesthe following steps of: 1, performing punch forming on silicon steel sheet raw materials; 2, rolling the silicon steel sheets; 3, conveying the silicon steel sheets onto a paint dipping device; 4, painting the silicon steel sheets; 4, cleaning the silicon steel sheets; 6, assembling the silicon steel sheets; and 7, installing the stator core body. According to the automobile starting motor statorcore and the automobile starting motor stator core machining process, the influence of tooth harmonics and temperature on a motor is reduced, so that the motor can operate more efficiently and stably, and the quality of the processed stator core body is better.

Description

technical field [0001] The present application relates to the technical field of electric motors, in particular to an automobile starter motor stator core and its processing technology. Background technique [0002] Motor stators are an important part of motors such as generators and starters. The motor stator is an important part of the motor. The motor stator is composed of three parts: the stator core, the stator winding and the frame. The main function of the motor stator is to generate a rotating magnetic field. [0003] In addition to generating a rotating magnetic field, the windings of an asynchronous motor also generate a series of harmonic magnetomotive forces. The harmonic magnetic fields generated by each harmonic magnetomotive force can be decomposed into phase-band harmonic magnetic fields and magnetic potential tooth harmonic magnetic fields. [0004] In view of the related technologies mentioned above, the tooth harmonic magnetic field is generated when the ...
