退火前后的电工钢中高频铁损变化浅析

Brief Analysis on High Frequency Core Loss Changes in Electrical Steel Before and After Annealing

本文针对电机铁损构成及其影响因素进行了理论推导,通过对比分析退火前后定子铁芯铁损测试,变频压缩机电机空载铁损测试和变频压缩机电机性能测试结果,得出了退火后电工钢的适用范围,为电机设计提供参考。

This paper introduces the compositions of core loss of the electric motor and its influence factors. Then it compares and analyzes the core loss test of stator core before and after annealing. Finally, according to the results about the idling core loss test and the performance test of the inverter compressor motor, the application scope of electrical steel is obtained for the reference for the motor design.
