Abstract Translated from German Stromregelung über jede Halbwelle je nach dem verlangten Moment zwischen rechteckförmigen und sinusförmigen Verlauf sowie unabhängig davon eine Verminderung der aktiven Wicklungsstrangzahl in Abhängigkeit von der Maschinendrehzahl. Current control over each half-wave depending on the required torque between the rectangular and sinusoidal curve and, independently of this, a reduction in the number of active windings as a function of the machine speed.
