摘要： A rotating electrical machine including a stator and a rotor having a rotor mass and permanent magnets, which are arranged on the surface of the rotor mass. The permanent magnets include a face which is directed towards the stator and is of a generally concave form. The permanent magnets of the rotor form poles of the rotor, in which the permanent magnet(s) of a same pole have an angular offset (a) between two longitudinal ends of the machine.
