Title:
FAILURE DETECTION METHOD AND SYSTEM OF PARALLEL COIL PERMANENT MAGNET MOTOR
Document Type and Number:
Japanese Patent JP2014117140
Kind Code:
A
Abstract:

To provide a failure detection method of a parallel coil permanent magnet motor, and to provide a supporting system therefor.

A failure detection method of a parallel coil permanent magnet motor includes a step for driving a parallel coil motor based on a predetermined current command value, a step for detecting the current vector of the motor, a step for calculating a current compensation value for removing the reverse-phase component of the motor based on the current vector, a step for providing the current compensation value to a reverse-phase current control machine, a step for calculating the failure phase of a parallel coil motor and the degree of failure 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 parallel 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.
