Abstract
An electric machine comprises a rotor () equipped with permanent magnets (), and a stator () equipped with electromagnetic poles. The electric machine is characterized in that several adjacent electromagnetic poles respectively constitute an electromagnetic pole group in which the adjacent electromagnetic poles are spaced apart at a first electromagnetic pole spacing, that adjacent electromagnetic poles belonging to different electromagnetic pole groups are spaced apart at an electromagnetic pole spacing greater than said first electromagnetic pole spacing, that each electromagnetic pole group has an even number of electromagnetic poles, and that adjacent electromagnetic poles of an electromagnetic pole group are linked to each other so as to generate magnetic fields of opposite direction in operation.
