Title:
CONTROL DEVICE FOR ELECTRIC BRAKE, CONTROL METHOD FOR ELECTRIC BRAKE, AND MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/259956
Kind Code:
A1
Abstract:
A motor control device comprising, as a control unit, a first control unit and/or a second control unit that serve as a control unit. The control unit outputs, to a first motor drive unit, a first current command for current supply to a first winding group so that a first torque which is larger than a torque generated in a brake motor by a torque command for generating a requested torque requested for the brake motor and which has the same direction as that of the requested torque is generated. In addition thereto, the control unit outputs, to a second motor drive unit, a second current command for current supply to a second winding group so that a second torque which is based on a difference between the requested torque and the first torque and which has the opposite direction to that of the first torque is generated.
