Abstract
A DC electric rotating machine mainly for the starter of an automotive vehicle, including: a stator having a magnetized structure with permanent magnetization and extending along the circumference of the stator; a rotor; a set of brushes adapted for the electric supply of the rotor by switching the electrical current in sections of the rotor; wherein the magnetized structure () of the stator includes at least one sector, between two consecutive magnetic poles (N; S) of the magnetized structure, having a magnetization vector that varies in an essentially sinusoidal manner upon displacement on the stator circumference, and wherein the angular deviation of the neutral line is selected so as to improve the switching during the operation of the machine.
