Abstract
A motor control device includes a switching element that controls a motor, a current control part that outputs a PWM signal for driving the switching element, and a setting part that sets a carrier frequency of the PWM signal. Further, a motor control part includes a torque ripple compensation part that sets a torque ripple compensation value based on a motor torque command value, the carrier frequency, and a rotation state of the motor. The current control part outputs the PWM signal based on the motor torque command value and the torque ripple compensation value.
