本节以五相感应电机为对象,研究定子绕组一相或多相开路时系统运行情况。根据电机无扰动运行(disturbance—freeoperation)条件,分析故障前后电机磁动势及电流。并推导在电机相开路情况下电机的解耦模型,以此为基础分析故障运行中电机容错控制。

By taking five-phase induction motor as object, the system runs is studied with one phase or multiphase stator winding open. Magnetic force and current are analyzed before and after trouble according to the condition of motor disturbance-free operation. Decoupling model of the motor is derived, and fault-tolerant control of the motor is analyzed when motor is trouble.
