Document Type and Number:
Japanese Patent JP7463989
Kind Code:
B2
Abstract:
To detect abnormalities of a coil in a motor with a simple configuration.SOLUTION: A motor control system 100 comprises a motor controller 40 and a detector 42. The motor controller 40 measures a d-axis current and a q-axis current of a motor 16 and calculates a d-axis control value vd and a q-axis control value vq on the basis of a difference between a d-axis current measurement value Id and a d-axis current command value Id* and a difference between a q-axis current measurement value Iq and a q-axis current command value Iq*. The motor controller 40 controls the motor 16 on the basis of the d-axis control value vd and the q-axis control value vq. The detector 42 detects abnormalities of a coil in the motor 16 on the basis of respective electrical secondary components of the d-axis control value vd and the q-axis control value vq.SELECTED DRAWING: Figure 2
