ABSTRACT:
A method of controlling the rotation speed of a motor to maintain it at a desired value, comprising a step of obtaining a deviation between the detected rotation speed and the desired value, and a step of changing the gain of a feedback loop, which serves to control the current flowing in the motor, to a value lower than a predetermined one during a period in which the deviation of the detected deviation in rotation speed is smaller than a preset maximum ripple value.
