Document Type and Number:
Japanese Patent JP2023144281
Kind Code:
A
Abstract:
To suppress deterioration of control performance when the temperature of a motor is low.SOLUTION: A motor control device for performing feedback control on a motor on the basis of a torque target value which is determined by a torque control unit on the basis of a torque command value and a motor state amount, includes a torque estimation unit that receives, as inputs, the torque command value and the state amount and determines the torque target value considering the temperature of a motor. The torque estimation unit outputs, as the torque target value, the torque command value within a low temperature region of the motor, and outputs a torque estimation value considering loss in the motor within a high temperature region of the motor.SELECTED DRAWING: Figure 1
