To provide a failure detection method of a series coil permanent magnet motor, and to provide a supporting system therefor.
A failure detection method of a series coil motor includes steps S101, 103 for driving a series coil motor based on a predetermined current command value, a step S105 for detecting the phase current vector of a motor, a step S107 calculating a current compensation value for removing the reverse phase (negative sequence) component of the motor based on the phase current vector, a step S109 for providing the current compensation value to a reverse phase current control machine, a step S111 for calculating the failure phase and the degree of failure of the series coil motor by using a failure model to which the output from the reverse phase current control machine, and the induction flux variation of a specific slot of a specific phase of the series coil motor failed and other slot of the same phase as the specific phase are applied, and an application step for applying a current command value to which the failure phase and the degree of failure thus calculated are applied.
