摘　　要：针对某舰谐波起动电动机在系泊试验中被烧毁的故障,采用理论分析与故障再现试验相结合的方法,查明了起动器中的断路器断相是导致电动机烧毁的根本原因,消除了对舰船第一次采用谐波起动电动机这一新技术的担忧。The theoretical analysis and fault recurrence experiment are used to find out the reasons of the burn-out fault of on board asynchronous motors started by harmonic field during the start up process in mooring test.It was proved that the loss of phase occurring in circuit breaker of starter leads to the burn-out fault of motors,which dispels the doubt of the innovative naval applications of asynchronous motor started by harmonic field.

关 键 词：电动机 谐波磁场 起动故障
