ABSTRACT OF THE DISCLOSURE The invention relates to a control circuit for a self-starting electric motor comprising a permanent magnet rotor, a stator with two windings, and, applied in series therewith to a DC operating voltage, electronic switching elements of which the switching conditions are so con- trollable by switching signals occurring in push-pull and derived from control signals of a sensor detecting the angular position of the rotor even on standstill, that the stator field changes direction in response to the angular position of the rotor, and comprising a magnetic field dis- tribution between the stator and rotor selected so that the rotor can assume an angular position as the rest position which is at most displaced in relation to the neutral position (the neutral angular position).
