Abstract:
1. A rotor for a rotary electrical machine that comprises two parallel magnet wheels that extend radially with respect to a principal axis of the rotor, each of which comprises a series of axial teeth, roughly trapezoidal in shape, comprising a base and a tip, that extend axially from the external radial end edge of said magnet wheel, in the direction of the other magnet wheel, so that each tooth on a magnet wheel is situated in the space existing between two consecutive teeth on the other magnet wheel, and that comprise magnetic elements, each of which is arranged between two adjacent teeth each belonging to one of the two magnet wheels, and is received partly in a groove produced in each of the opposite lateral faces of said two adjacent teeth, wherein one of said grooves produced in one of said two adjacent teeth emerges at said base of said tooth and the other of said grooves produced in an opposite lateral face of said adjacent tooth faces said groove emerging at said base of said tooth and emerges at a tip of said adjacent tooth: wherein each of said two adjacent teeth comprises at most one groove at a maximum which emerges at its base.
