Abstract:
A motor control device capable of improving damping effects of a motor. In a motor control device, a control switching determination unit determines whether or not a control region of a motor is in a voltage saturation region. A voltage command value generator generates a voltage command value of the motor based on a velocity command value and a velocity of the motor. When the control switching determination unit determines that the control region of the motor is in the voltage saturation region, the voltage command value generator determines a voltage vector angle of an output voltage applied to the motor from a total torque command value and a limit value of the maximum voltage capable of being output to the motor, and generates a voltage command value based on the voltage vector angle.
