Abstract

A motor control device includes: a noise reduction unit that sets a PWM count in units of PWM cycles for each PWM cycle in a current control cycle such that a current that flows through a frame ground because of a phase voltage for any one of three phases is canceled out with a current that flows through the frame ground because of a phase voltage for one of the two other phases in each PWM cycle in the current control cycle; and a noise canceling circuit configured to generate a current that is opposite in phase to a current that flows through the frame ground because of a phase voltage for the other of the two other phases in each PWM cycle in the current control cycle.
