Abstract

Elektrische Maschine (10), mit einem Stator (16), der ein Ständereisen (17) aufweist, welches eine im Wesentlichen zylindrische Öffnung (60) mit einer zentralen Achse (63) hat und die Öffnung (60) einen Rotor (20) aufnimmt, wobei das Ständereisen (17) eine axiale Länge (L17a) hat, und das Ständereisen (17) eine Ständerwicklung (18) hält, mit dem Rotor (20), der eine Drehachse (66) besitzt, wobei der Rotor (20) eine axiale Stirnseite (69) hat, an der ein Lüfter (30) mit Lüfterschaufeln (72) angeordnet ist, der drehfest mit dem Rotor (20) verbunden ist, wobei der Rotor (20) einen elektromagnetisch erregbaren Pfad (75) aufweist, der einen Polkern (78) hat, an den sich an beide drehaxialen Enden (80, 82) je eine Polplatine (22, 23) anschließt, wobei von der einen Polplatine (22) Klauenpole (24) ausgehen, die eine Nordpolarität haben und von der anderen Polplatine (23) Klauenpole (25) ausgehen, die eine Südpolarität haben, wobei sich am Umfang des Rotors (20) die Klauenpole (24) und (25) nach Nordpolarität und Südpolarität abwechseln, und der Rotor (20) einen eine Längsrichtung (86) aufweisenden Zwischenraum (21) zwischen zwei benachbarten gegenpoligen Klauenpolen (24, 25) hat, wobei in dem einen Zwischenraum (21) zwischen den zwei Klauenpolen (24, 25) eine permanentmagnetische Einrichtung (88) einsitzt, wobei die permanentmagnetische Einrichtung (88) eine Länge (L88) in Längsrichtung (86) des Zwischenraums (21) hat, mit einem radial innerhalb der Klauenpole (24, 25) angeordneten Polkern (78), der eine drehaxiale Länge (L78) hat, und ein Verhältnis aus der Länge (L88) der permanentmagnetischen Einrichtung (88) und der drehaxialen Länge (L78) des Polkerns (78) größer als 1,3 ist.
