Abstract

Die vorliegende Erfindung betrifft einen Elektromotor (3), mit einem Rotor (7) und einem Stator (8), die konzentrisch zu einer Rotationsachse (11) angeordnet sind und relativ zueinander um die Rotationsachse (11) drehverstellbar sind, wobei der Elektromotor (3) als Außenläufer, bei dem der Rotor einen Außenrotor (7) und der Stator einen Innenstator (8) bildet, oder als Innenläufer ausgestaltet ist, bei dem der Stator einen Außenstator (8) und der Rotor einen Innenrotor (7) bildet, wobei der Rotor (7) wenigstens zwei Permanentmagnete (12) aufweist und wobei der Stator (8) wenigstens zwei Polarme (16, 17) und wenigstens eine elektrische Spule (18) aufweist. Ein vereinfachtes Anfahren ergibt sich, wenn der Rotor (7) in der Umfangsrichtung (13) symmetrisch gestaltet ist und wenn der Stator (8) in der Umfangsrichtung (13) asymmetrisch gestaltet ist.
