Abstract

The invention relates to a motor vehicle engine starter having a rotary electric machine with a perfected salient pole inductor, and a corresponding pole shoe. The invention mainly relates to a motor vehicle heat engine starter comprising a rotary electric machine (5) that has a rotor (9) and a stator (8) and comprises a plurality of magnetic poles (65) arranged on an internal circumference of a yoke (66). Each magnetic pole (65) is made up of a salient pole shoe (69) surrounded by a winding (70). Said starter is characterized in that an air gap (76), separating said rotor (9) from the magnetic poles (65) of said stator (8), varies according to the circumference thereof. The invention also relates to a corresponding pole shoe (69).

Description

technical field [0001] The invention relates to a starter for a motor vehicle thermal engine provided with a rotating electrical machine with improved salient pole inductors, and to a corresponding pole shoe. The invention has a particularly advantageous but not exclusive application with starters of so-called stop and start systems, which make it possible to stop and restart the thermal engine of a vehicle, in particular according to traffic conditions. Background technique [0002] In order to start a heat engine, in particular of a motor vehicle, it is known to use a starter provided with a starting device which can transmit the rotational energy of the starter to the crankshaft of the heat engine via a starter ring. The starting device is assembled on the drive shaft. According to one embodiment, a reducer is interposed between the drive shaft and the shaft of the electric motor. [0003] The electric motor comprises firstly a rotor, also called armature, and secondly ...
