Abstract
The invention relates to an engine control for a synchronous motor having a number of N stator coils set off in regard to each other, which are arranged around a rotor of the synchronous motor, wherein there may be impressed upon the stator coils by the engine control a coil voltage and wherein there is formed a coil current having a direct current component in a co-ordinate system rotating proportionally with the number of revolutions performed by the synchronous motor as well as a cross current component, wherein the cross current component effects a tangential force activating the rotor in the direction of rotation and wherein the direct current component effects a force acting perpendicularly to the rotor surface on the rotor, wherein the engine control has a direct current generator for generating a direct current component periodically alternating in the rotating co-ordinate system, in order to neutralize oscillations of the synchronous motor activated by the engine control by means of the force generated perpendicularly to the rotor surface, wherein the direct current generator is formed for evaluating at least one angle information and an operating cross current.
