Abstract
A method of controlling the rpm of a motor by employing an incremental indicator or sensor (rpm), in which motor control with a reduced starting torque and a reduced startup short-circuit current is intended to be attained in a simple manner. For this purpose a control signal guided to a power output stage that actuates the motor is pulse-width modulated.
