Abstract
A motor drive device includes a motor having a rotor, and a control device that controls the motor. The control device calculates a first value based on a d axis current and a q axis current of the motor. The control device calculates a second value by integrating the first value. The control device calculates a third value by performing prescribed control for making the second value equal to zero. The control device performs, based on the third value, position control for causing a rotational position of the rotor to match a designated position.
