VERFAHREN ZUM STEUERN EINES MECHANISCH KOMMUTIERTEN ELEKTROMOTORS

摘要

A method for controlling a mechanically commutated electric motor, wherein the rotational angle of the output of said motor is determined by means of detection of the change in back electromotive force, when the electric motor commutates, and wherein the power supply to the electric motor is halted after a predetermined number of detected commutations.
