Abstract

Die Erfindung bezieht sich auf eine elektrische Maschine mit einem um eine Drehachse 2 drehbar gelagerten Rotor und einem den Rotor umschließenden Stator und einer oder mehreren Ausnehmungen 1 zur Aufnahme von rechteckförmigen Dauermagneten 4, 4'. Dabei sind die Dauermagnete 4, 4' in der Ausnehmung 1 von einem Kunststoff 12 vollständig oder teilweise umschlossen. Eine Ausnehmung 1 weist in Umf angsrichtung des Rotors nebeneinander zwei Aufnahmebereiche 5, 5' auf, wobei in jedem Aufnahmebereich 5, 5' ein Dauermagnet 4, 4' angeordnet ist und wobei die Dauermagnete 4, 4' gleiche Polarisationsrichtung aufweisen und durch einen oder mehrere Abstandshalter gegen einander berühren voneinander in Abstand gehalten sind.
