Title: Elektronisch kommutierbarer Motor
Inventor: HEINKEL HANS-MARTIN
IPC: H02P6/30
Filed: 1999-07-23
Abstract: Die Erfindung betrifft einen elektronisch kommutierbaren Motor, dessen Erregerwicklungen über Halbleiter-Endstufen von einer elektronischen Steuereinheit mittels pulsweitenmodulierter Steuersignale bestrombar sind und dabei im Stator des Motors ein Drehfeld erzeugen, das den Dauermagnet-Rotor des Motors in Drehbewegungen versetzt. Ohne Lagesensoren wird ein sicherer Anlauf in der Drehrichtung auch bei hohem Massenträgheitsmoment, kleinem Rastmoment und schlechter Bedämpfung dadurch erreicht, dass beim Start des Motors die Steuereinheit während einer vorgegebenen oder vorgebbaren Startphase die Halbleiter-Endstufe in sich überlappenden Steuerphasen mit PWM-Steuersignalen ansteuert, deren Pulsweitenverhältnisse von einem Minimum auf ein Maximum ansteigt und wieder auf das Minimum abfällt, dass die sich überlappenden Bereiche der Steuerphasen in den betroffenen Erregerwicklungen Ströme erzeugen, die einen annähernd kontinuierlichen Momentenverlauf ergeben, und dass in der Startphase durch Verkürzung der Kommutierungszeit zwischen den aufeinanderfolgenden Steuerphasen die Kommutierungsfrequenz und damit die Drehzahl des Motors erhöht wird.
