Die kernlosen, bürstenbehafteten DC-Motoren verdanken ihre anhaltende Popularität der Kombination aus einfachem Aufbau, schnellen Einschwingvorgängen, zu vernachlässigen Eisenverlusten und einfacher Steuerung. Da die Drehzahl proportional zur angelegten Spannung ist, kann der Motor ganz einfach über eine Stromversorgung mit Linerarregler betrieben werden. Aber ist das immer die beste Lösung?
Dr. Sunil Kedia, Core Market New Product Development Manager bei Portescap, erläutert die Vorteile des PWM-Antriebs als Alternative und Faktoren wie die optimale Frequenz, Stromwelligkeit und Lebensdauer für die Steuerung bürstenbehafteter DC-Motoren.
Von der Robotik und Industrieautomation bis hin zu Haushaltsgeräten und sogar Spielzeug gibt es zahlreiche Anwendungen für bürstenbehaftete DC-Kleinstmotoren, die
