Title:
MOTOR CONTROL DEVICE AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/187678
Kind Code:
A1
Abstract:
To realize control having excellent ease of use with respect to a motor having mutually independent windings. A motor control device 10 controls a motor 200 so that a phase current based on a torque command value that is an input command value flows through at least one of a U-phase winding 201, a V-phase winding 202, and a W-phase winding 203 of the motor 200, and so that a prescribed same-phase current is superposed on the phase current and flows through at least one of the U-phase winding 201, the V-phase winding 202, and the W-phase winding 203. The motor control device 10 controls the motor 200 so as to stop energization to any one winding that corresponds to a prescribed energization stop phase from among the U-phase winding 201, the V-phase winding 202, and the W-phase winding 203, e.g., to the U-phase winding 201, and so as to allow a V-phase current, a W-phase current, and the same-phase current to flow through each of the windings that correspond to phases other than the energization stop phase, e.g., through the V-phase winding 202 and the W-phase winding 203.
