Abstract
A motor control device includes an electric power converter for generating three-phase voltages based on voltage instruction-values, and for supplying them to a motor; an induced-voltage estimation unit for estimating an induced voltage of the motor, based on the voltage instruction-values and electric current feedback values; a dead-time disturbance-voltage compensation unit; and a dead-time disturbance compensation-voltage modification unit for compensating a dead-time disturbance voltage(s) generated in the electric power converter, based on a fundamental wave component of an estimated induced voltage.
