Abstract

Die Erfindung bezieht sich auf eine Elektrische Maschine, insbesondere einen Elektromotor mit einem Stator (2) sowie einem um eine Rotorachse (3) drehbar gelagerten Rotor (1, 1 ') mit einem Rotorkörper (4), wobei in Aufnahmen (5a, 6a, 35a, 47a, 55a, 55'a) des Rotorkörpers Permanentmagnete (17, 17', 18, 18', 18", 24, 24', 25, 26, 27, 28, 29, 29', 30, 32, 33, 34, 35, 48, 49, 57) angeordnet sind, die wenigstens teilweise aus einem Mischwerkstoff bestehen, wobei die Mischung derart eingestellt ist, dass der Mischwerkstoff eine Remanenzfeldstärke Br zwischen 0,6 Tesla und 1 Tesla sowie eine Koerzitivfeldstärke Hcj zwischen 1300 und 2500 KA/m aufweist. Zudem kann vorgesehen sein, dass in Aufnahmen (5a, 6a, 35a, 47a, 55a, 55'a) Permanentmagnete (17, 17', 18, 18', 18", 24, 24', 25, 26, 27, 28, 29, 29', 30, 32, 33, 34, 35, 48, 49, 57) oder Kompositkörper (47) angeordnet sind, und dass diese eine Kontur aufweisen, deren senkrecht zur Längsachse (7) liegende Querschnittsfläche sich innerhalb der jeweiligen Aufnahme (5a, 6a, 35a, 47a, 55a, 55'a) zu deren radial weiter außen liegendem Ende (5b, 6b) hin verringert.
