Abstract

Die Erfindung bezieht sich auf permanentmagneterregte Drehfeldmotoren mit Bruchlochwicklung. Bei diesen Elektromotoren besteht nach wie vor das Problem eines hohen Rastmoments, welches insbesondere beim Durchdrehen des stromlosen Motors mittels eines äußeren Drehmoments unerwünscht ist. Zur Lösung des Problems wird vorgeschlagen, daß das Rastmoment jedes einzelnen Permanentmagneten (5, 6) innerhalb jeder Halbteilung (b), die als Winkelabstand zwischen den Mittelebenen eines Stegs (2) und einer benachbarten Nut (3) des Stators (1) definiert ist, symmetrisch zur Mittelebene der Halbteilung (b) verlaufen soll und daß eine ungerade Anzahl von über- und unterzähligen Nuten vorliegt. Als Ergänzung oder Alternative wird vorgeschlagen, eine Anzahl von Permanentmagneten (5, 6) zu wählen, die keinen gemeinsamen Teiler mit der Anzahl der über- oder unterzähligen Nuten aufweist. Mögliches Anwendungsgebiet sind alle Antriebe mit permanentmagneterregten Drehfeldmotoren.
