Forming method of disc type motor rotor

Abstract

The invention provides a forming method of a disc type motor rotor. The method comprises the following steps of (a) providing a non-magnetic retainer which is provided with a radial limiting piece and a plurality of circumferential limiting pieces; (b) providing a magnetic conductive assembly, wherein the magnetic conductive assembly is provided with a plurality of magnetic conductive blocks and a yoke piece; (c) embedding the circumferential limiting pieces between the two adjacent magnetic conductive blocks and abutting against the yoke piece so as to form a limiting channel between the magnetic conductive blocks and the circumferential limiting pieces; (d) arranging an inner ring at the outer side of the magnetic conductive block in a sleeving manner; (e) enabling the plurality of axial limiting nails to sequentially penetrate through the guide holes one by one and inserting the plurality of axial limiting nails into the limiting channels; (f) arranging an outer ring at the outer side of the inner ring in a sleeving mode, and fixing the axial limiting nails. The forming method is convenient and rapid, the magnetic conductive sheets are effectively prevented from being dispersed in the rolling process, the industrial batch production can be easily carried out, the performance of a rotor is improved, and the service life is further prolonged.

Description

technical field [0001] The invention relates to the field of disc motors, in particular to a method for forming a disc motor rotor. Background technique [0002] Motor refers to an electromagnetic device that converts or transmits electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machinery. The motor includes a stator and a rotor. The stator is the static part of the electric motor. It is mainly composed of a stator core and a stator winding. The role of the stator is to generate a rotating magnetic field so that the rotor is cut by the magnetic force lines in the magnetic field to generate current. [0003] Among them, motors can be divided into radial field motors and axial field motors. Axial field motors are also called disc motors. They have the characteristics of small size, light weight, short axial dimension and high power density, and can be used i...

Problems solved by technology

In the switched reluctance motor, it is necessary to use a magnetic block with excellent magnetic permeability to improve its motor performance. At present, the magnetic block formed by stacking sheet-shaped silicon steel sheets has excellent magnetic permeability, but the magnetic block formed by stacking sheet-shaped silicon steel sheets Medium-silicon steel sheets and silicon steel sheets are discrete, making it difficult to carry out industrial production
