摘要
The present invention relates to a permanent magnet motor. Disclosed are a method and system for detecting a fault of a parallel coil type permanent magnet motor. This method includes driving a parallel coil type motor on the basis of a pre-defined current reference value, detecting a phase current vector of the motor, and calculating a current compensation value for removing a negative sequence component of the motor on the basis of the phase current vector. The method further includes providing the current compensation value to a negative sequence current controller, calculating a faulty phase and a degree of fault of the parallel coil type motor by using the output of the negative sequence current controller and a fault model considering both flux variation in a specific slot of a specific phase of the parallel coil type motor and induced flux variations in other slots of the same phase when the parallel coil type motor has a fault, and applying a current reference value to which the calculated faulty phase and degree of fault have been applied.
