Title:
MOTOR CONTROL DEVICE, AND STEERING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/256312
Kind Code:
A1
Abstract:
A motor control device (80) comprises: a first inverter (120) connected to a first winding set (180) and a first power supply unit (191); a second inverter (220) connected to a second winding set (280) and a second power supply unit (291); a first control unit (170) that calculates a first required voltage to be output from the first inverter, on the basis of a command value of torque of a motor (10), and, if the first required voltage is not higher than a first upper limit voltage, controls the first inverter on the basis of the first required voltage, and, if the first required voltage is higher than the first upper limit voltage, controls the first inverter on the basis of a voltage decreased from the first required voltage; and a second control unit (270) that calculates a second required voltage to be output from the second inverter, on the basis of the command value, and controls the second inverter on the basis of the second required voltage.
