Abstract
The invention relates to a 2N pole claw rotor comprising a first magnetic material part, comprising an axial hub having a free end, and an end provided with N axially-extending claws that are peripherally localized, uniformly distributed, and together define a bezel; a second magnetic material part of polarity opposite to the polarity of the first magnetic material part, having the same shape as the first magnetic material part, and disposed facing the first magnetic material part, each claw of the second magnetic material part being disposed between two claws of the first magnetic material part, and vice versa; non-magnetic spacers interposed between the free ends of the claws and the end walls of the bezels of the facing parts; and non-magnetic rotor-cowling means.
