摘　　要：对高压异步电动机的起动进行了分析；对用于驱动风机、水泵、磨煤机和排粉机等重载起动设备的高压异步电动机造成频繁损坏的机理进行了合理的解释。通过采用维持定子不变，对转子铁心、笼条、端环进行重新优化设计以得到理想的起动性能的技术改造方法，使电动机的起动转矩提高，起动时间缩短，避免转子损坏，为解决普通异步电动机驱动重载起动设备损坏的问题找到了一条低投入、高性能输出的有效途径。High -voltage asynchronous motor; on to drive fans, pumps, coal pulverizers and the start of mill fan and other heavy load starting equipment, high voltage asynchronous motor damage caused by frequent mechanism was a reasonable ex- planation were analyzed . Remain unchanged through the use of the stator, rotor core, cage bar, end ring to re - optimize the design to be the ideal starting performance of the technical transformation method to improve the motor starting torque, starting time shortened to avoid damage to the rotor, in order to solve the general induction motor - driven heavy load dam- age to the equipment problems start to find a low input, high - performance output effective way were introduced.
