Abstract

Die Erfindung betrifft eine elektrische Maschine (2), insbesondere Elektromotor eines Kraftfahrzeugs, mit einem Stator (8) und mit einem eine Rotationsachse (4) aufweisenden Rotor (6). Unter elektrischer Maschine (2) wird hierbei insbesondere ein bürstenloser Elektromotor (Gleichstrommotor) oder eine Synchronmaschine, jedoch auch ein Generator verstanden. Der Stator (8) oder der Rotor (6) weisen eine Elektromagnetenstruktur (12) und der anderen eine Permanentmagnetenstruktur (34) auf, die eine ersten Menge (36) von Permanentmagneten (32) und eine zweite Menge (38) von Permanentmagneten (32) umfasst. Bei zumindest der Betriebstemperatur (T) ist die magnetische Koerzitivfeldstärke (Hcji) der ersten Menge (36) größer als die magnetische Koerzitivfeldstärke (Hcj2) der zweiten Menge (38). Die Erfindung betrifft ferner zwei Verfahren zur Herstellung von Hybridmagneten (40).
