变频电动机振动转矩特性测定的新方法

A New Measurement Method of Vibration Torque on the Three-Phase Induction Motor Supplied by Frequency Converter

目前,变频调速系统仍然是用变频器驱动普通的异步电动机。而变频器输出的大量高次谐波产生的振动转矩已经影响到整个变频调速系统性能的提高。文章提出一种变频器电源供电下三相异步电动机振动转矩特性测定的新方法,并用实验证明此方法的正确性,对今后变频电机的设计有一定参考作用。

Today, most frequency-conversion system still is composed of the common induction motor supplied by a frequency converter. As a result, greater vibration torque occured and it restrictd the performance of the whole system. The paper presented a new measurement method of vibration torque for the better design of the frequencyconversion motor. At last, a series of tests proved the validity.
