Abstract

Rotor an alternator or alternator-starter type comprises two pole wheels including a series of axial claws having a generally trapezoidal shape that extend axially from the edge of the outer radial end of one pole wheel towards the other pole wheel. The rotor comprises an interpolar magnetic assembly in the interpolar space between a first claw of a first pole wheel and a second claw of a second pole wheel. The magnetic assembly comprises two first faces defined by first and second free ends. A side face is also provided, such that the adjacent side face faces same, the side face comprising third and fourth opposing ends between which the magnet is in contact. The side faces of the first and second claws define a reduction in cross-section from one of the free ends of the magnetic assembly extending towards a claw head end along a side facet.
