Abstract:
A rotor for an electrical machine that comprises two parallel magnet wheels, each of which comprises axial teeth so that each tooth on a wheel is situated in the space existing between two consecutive teeth on the other wheel, and that comprises magnetic elements, each arranged between two adjacent teeth and partly received in a groove produced in each of the opposite lateral faces of the two adjacent teeth. In one embodiment, each of the two adjacent teeth comprises one groove at a maximum, which emerges at the base of the first tooth.
