Abstract: The paper introduced a new fault-tolerant permanent magnet motor and presented a fault-tolerant permanent magnet motor design approaches and fault-tolerant technique characteristics.It resolved the difficult problems during the motor asymmetry operation.The aim is to develop a normal drive when any windings or drivers failed and the motor is in asymmetry operation.It also verfied the magnetic isolation and limiting of short-circuit fault current performances of fault-tolerant permanent magnet motor by using 2D simulation and test methods.This method testifies the motor has a good fault-tolerant characteristic.
