Document Type and Number:
Japanese Patent JP6674765
Kind Code:
B2
Abstract:
It is an object of the present invention to reduce detection error of zero-phase current. A control device of a motor in which a winding is independently connected for each phase, the control device including: a control unit controlling a voltage applied to the motor on the basis of a torque command value, wherein the control unit provides a first period in which a zero-phase voltage pulse for outputting a zero-phase voltage for reducing a zero-phase current which is determined based on an alternating current of each phase is output, and a second period in which a current of each phase flowing in the motor is detected, and the first period and the second period are not overlapped.
