Abstract (en)
[origin: WO2008074954A1] The invention relates to a DC electric rotating machine mainly for the starter of an automotive vehicle, said machine including: a stator having a magnetised structure with permanent magnetisation and extending along the circumference of the stator; a rotor; a set of brushes adapted for the electric supply of the rotor y switching the electric current in sections of the rotor; the machine being characterised in that the magnetised structure (5) of the stator includes at least one sector, between two consecutive magnetic poles (N; S) of said structure, having a magnetisation vector that varies in an essentially sinusoidal manner upon displacement on the stator circumference, and in that the angular deviation of the neutral line is selected so as to improve the switching during the operation of the machine.
