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), bei dem in Aufnahmen (5a, 6a) wenigstens zwei Permanentmagnete in Form von Teilmagneten (17, 17', 18, 18', 18", 24, 24', 25, 26, 27, 28, 29, 29', 30, 32, 33, 34, 35, 48, 49, 57) angeordnet sind, von denen ein Erster zu einer ersten Menge von Permanentmagneten und ein Zweiter zu einer zweiten Menge von Permanentmagneten gehört und wobei die Permanentmagnete der ersten Menge sich von den Permanentmagneten der zweiten Menge bezüglich der stofflichen Zusammensetzung, insbesondere bezüglich der magnetischen Eigenschaften unterscheiden, und wobei wenigstens ein Permanentmagnet der ersten oder zweiten Menge oder wenigstens ein Kompositkörper (47) 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.
