Rotor dynamic balance correction method, rotor and motor

Abstract

The application provides a rotor dynamic balance correction method, a rotor and a motor. The rotor includes a rotating shaft, an iron core with 2p magnetic poles and magnetic tiles. The rotating shaft has a shaft extension end and a non-shaft extension end. On the bit plane, the iron core is formed by laminating multiple pieces of magnetically conductive sheets; the multiple magnetically conductive sheets include N1 first balance punches and N2 second balance punches; the first balance punches are provided with m1 first balance holes , the overall centroid of the m1 first balance holes is located on the side away from the flat plane of the rotating shaft; m2 second balancing holes are arranged on the second balance punch, and the overall centroid of the m2 second balancing holes is located on the side close to the flat position of the rotating shaft side of the face. In this application, the first balance hole is directly set on the first balance punch in the magnetic conductive sheet forming the rotor core, and the second balance hole is set on the second balance punch to ensure the dynamic balance of the rotor, and there is no need for subsequent adjustment of the rotor. The assembly is corrected for dynamic balance, which can improve production efficiency and reduce costs.

Description

technical field [0001] The present application belongs to the field of motors, and more specifically relates to a rotor dynamic balance correction method, a rotor and a motor. Background technique [0002] In order to assemble the load, the motor often sets one or more flat surfaces on the shaft extension end of the rotating shaft to fix the load, so as to prevent the assembled load from sliding and loosening along the circumferential direction of the rotating shaft. However, the flat surface on the rotating shaft will cause the mass eccentricity along the axis, resulting in a dynamic unbalance in the rotor, which will cause a large vibration and noise problem during the operation of the motor, so the dynamic balance correction of the rotor is required. [0003] At present, there are two main methods for dynamic balance correction of motors, namely weight gain and weight removal; the weight gain method is to set an installation station on the rotor, insert balance nails and ...
