MOTOR REGULATION FOR A SYNCHRONOUS MOTOR

摘要

The invention relates to a motor regulation (8; 22) for a synchronous motor (1), which has a number of N stator coils (7) arranged offset to each other, which are arranged around a rotor (4) of the synchronous motor (1), wherein a coil voltage (US) can be inserted into the stator coils (7) by the motor regulation (8; 22) and a coil current (IS) is formed which has a direct current component (ID; IDW) and a transverse current component (IQ) in a coordinate system proportional to the speed of the synchronous motor (1), wherein the transverse current component (IQ) effects a tangential force (FT) driving the rotor (4) in the direction of rotation and wherein the direct current component (ID) effects a force (FR) perpendicular to the rotor surface on the rotor (4), wherein the motor regulation (8; 22) has a direct current generator (20) for generating a direct current component (IDW), periodically alternating in the rotating coordinate system, in order to equalize oscillations of the synchronous motor (1) driven by the motor regulation (8; 22) by the force (FR) generated perpendicular to the rotor surface, wherein the direct current generator is designed to evaluate at least one angle information and one regulation transverse current.
