摘要
分析了变频电机轴电流产生机理、流通路径及危害,阐述了轴电压测量方法和经验限值,并从变频电机本身运行机理和结构角度出发,介绍了防止变频电动机轴电流危害的措施。
The mechanism of shaft current was analyzed,and as well as its flow path and detriment. Shaft voltagemeasurement method and experience limit value were also given. Based on the structure and the operating principle offrequency control motor,preventions of shaft current were introduced.
