阐述了变频电机由变频器供电时,由于电源电压的非正弦,会在电机绕组线匝上产 生高电压,本文用实验的方法论述了绕组上电压的分布情况。 关键词变频电动机变频器电压 Abstract The paper relates that high voltage can occur in the coils ofthe motor windings due to non·-sinusoidal supply voltage when the variable·-frequency motor is supplied from the converter,and discusses the voltage distribution in winding by the experiment. Key words Variab le-frequency motor,converter,voltage.
