异步起动永磁同步电动机实际应用问题研究

Study on Practical Application of Asynchronous Starting Permanent Magnet Synchronous Motor

异步起动永磁同步电动机比其他电动机的功率更高,单位体积内的能量密度更大,产生的效果更高。但在电动机实际应用过程中,仍旧会出现超载、反转与不同步的现象。本文主要围绕异步起动永磁同步电动机的退磁现象、堵转问题,针对实际案例分析其产生问题的原因,并给出控制退磁、减少堵转的解决方案。

Asynchronous starting permanent-magnet synchronous motors have higher power than other motors and have higher energy density per unit volume,resulting in higher efficiency.However,in the actual application of the motor,there will still be overloaded,reversed and out-of-synchronization phenomena.This paper mainly focuses on the demagnetization phenomenon and stalling problem of the asynchronous starting permanent magnet synchronous motor.It analyzes the causes of the problem for the actual case and gives solutions to control demagnetization and reduce stall.
