Abstract

The present invention relates to a device in an electronic driving dynamics control system, comprising an electromechanic transducer, especially an electric motor, a hydraulic pump, and an electric actuating unit for the transducer, said transducer including a magnetic or magnetizable stator and a rotor, as well as connections for connecting the actuating unit, and a commutation device for the actuation of electromagnetic windings of the rotor, said invention inhering the special feature that the commutation device comprises three or more commutating elements that are electrically connected to the respective connections so that the windings of the rotor can be actuated individually by the actuating unit, with at least one commutating element being connected to a change-over element that provides for an additional connection for connecting a rotational speed measurement devices.
