Claim 8:
9. A motor control method, comprising:
a current control step of performing current control for rotating a motor from a stop state;
a rotation speed calculation step of calculating an actual rotation speed of the motor;
an acquisition step of acquiring a target rotation speed, which is a target value relating a rotation speed of the motor;
a speed control step of performing speed control of the motor, so that the actual rotation speed of the motor calculated in the rotation speed calculation step becomes the target rotation speed acquired in the acquisition step; and
a correction step of correcting, at a time of a transition from a current control state in the current control step to the speed control performed in the speed control step, the target rotation speed acquired in the acquisition step based on a relation between the actual rotation speed of the motor calculated in the rotation speed calculation step and the target rotation speed acquired in the acquisition step,
wherein in the speed control step, in a case where the target rotation speed acquired in the acquisition step is corrected by the correction step, the speed control is performed, so that the actual rotation speed of the motor calculated in the rotation speed calculation step becomes the target rotation speed corrected in the correction step.
