Patent ID: 11264849

Abstract:
The present disclosure relates to a rotor (3) for an electric machine (1). The rotor (3) includes a plurality of magnet poles (5a-f; 5a-h) each comprising one or more permanent magnets (6-n). The magnet poles (5a-f; 5a-h) are angularly separated from each other and an inter-pole region (7a-f; 7a-h) is formed between adjacent magnet poles (5a-f; 5a-h). At least one external flux barrier (12-1, 12-2) is disposed in each said inter-pole region (7a-f; 7a-h), the at least one external flux barrier (12-1, 12-2) comprising an external aperture. The present disclosure also relates to an electric machine (1) including a rotor (3); and to a vehicle (2) including an electric machine (1).
