Abstract

This motor control device, which controls a motor (4) that drives a load element having periodic load torque variation, is provided with a detection unit that detects the amplitude of a current driving the motor (4), and a correction unit (10) that corrects a motor drive voltage for driving the motor (4). The correction unit (10) estimates, from the entire range of electrical angles of the motor (4) corresponding to one period of the load element, a first electrical angle at which the motor drive current detected by the detection unit reaches a maximum peak, classifies the entire range of electrical angles into one electrical angle range including the first electrical angle and another electrical angle range excluding said one electrical angle range, and carries out a first correction in which the motor (4) drive voltage is reduced more in said one electrical angle range than in said other electrical angle range.
