摘　　要：三相突然短路是对电机有严重危害的过渡过程。文章从分析三相突然短路时电枢绕组的磁链变化出发,给出了永磁同步发电机三相突然短路时短路电流的计算方法、三相突然短路时永磁体的最大去磁校核计算式,为永磁同步发电机的可靠性设计提供依据。Three-phase sudden short-circuit can cause terrible damage to a generator. After analyzing the magnetic flux linkage change when magneto ahemator is occurring three-phase sudden short-circuit, this paper gives the short-circuit current calculating method and means to check the permanent magnet degaussing, which provides a basis for design of magneto alternator.
