Abstract

Official abstract text for this publication.

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 ( 5 ) 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.

First claim

Opening claim text (preview).

The invention claimed is: 1. A direct current rotating electrical machine for an automotive vehicle starter ( 1 ), the machine including: a stator ( 3 ) including a magnetised structure with permanent magnetisation, extending along a circumference of the stator and having north and south poles; a rotor ( 2 ); and a group of brushes ( 13 , 14 ) adapted to supply electrical power to the rotor by switching the electrical current in sections of the rotor, the magnetised structu…
