浅议交流永磁同步电梯曳引机的泄漏电流

Discussion on the Leakage Current of the PM Motor of the Elevator Traction Machine

从泄漏电流的定义和成因出发，说明了泄漏电流的概念。对电动机安全的国家标准中关于泄漏电流的内容作了阐述，总结了交流永磁电梯曳引机的泄漏电流的特点，并对泄漏电流和耐压试验的跳闸（脱扣）电流进行了区分和对比。

This paper introduces the concept of the leakage current and the rules of the motor leakage current in relation to the state standards. It also puts forward the characteristic of the leakage current of the PM motor of the traction machine and compares to this leakage current with the tripping current at the voltage-proof test.
