To stop a motor on an accurate position and to shorten time to be required for stop control.

The motor controlling method for stopping an object on a prescribed target position drives a motor at a 1st required speed (high speed) up to the 1st prescribed distance Ls of a prescribed target position, brakes the motor to a prescribed speed slower than the required speed by using a primary brake, drives the motor at a 2nd required speed (low speed) slower than the 1st required speed up to the 2nd prescribed distance Lb of the prescribed target position, and then stops the object on the prescribed target position by using a secondary brake.
