Embodiment Construction

[0040] Identical, similar or analogous elements retain the same reference numerals from one figure to another.

[0041] refer to figure 2 , the starter 11 according to the invention in particular comprises a drive shaft 12, a starter drive assembly 13 mounted on the drive shaft 12, and an electric motor 15 comprising an induction rotor 17 fixed to a shaft 18 and an induction stator 16. The motor 15 comprises a housing 21 mounted on a support 22 of the starter 11 intended to be fixed to a stationary part of the motor vehicle.

[0042] A speed reducer 23 with planetary type gears is preferably inserted between the shaft 18 of the electric motor 15 and the rear end of the drive shaft 12 .

[0043] The starter 11 also includes an electromagnetic contactor 25 extending parallel to the electric motor 15 by being located radially above the electric motor 15 . The contactor 25 has a metal case 28 equipped with a set of exciting coils 29a, 29b. The terminals 31 , 32 are configured...

Abstract

The invention mainly relates to a starter for a thermal engine of a motor vehicle, comprising: at least one electromagnetic contactor, including a positive output terminal, at least one electric motor, comprising: at least one brush holder (43), at least a positive brush (35), mounted in said brush holder (43), an electrical path (91), between said positive brush (35) and the positive output terminal (32), and at least one thermal protector (96) in said electrical path (91), wherein said thermal protection is adapted to disconnect said two elements (93, 95) to relatively The positive output terminal is electrically disconnected from the positive brush (35).

Description

technical field [0001] The invention relates to a motor vehicle starter provided with a thermal protection function. The invention is particularly advantageously, but not exclusively, applicable to starters of systems for automatically stopping and restarting thermal engines, known as "stop and start" systems. Background technique [0002] As known per se, starters comprise protection against overcurrents in the form of one or more fuses and / or one or more circuit breakers. figure 1 An exemplary starter motor 1 is thus shown comprising a fuse 2 mounted in series between the mains terminal 3 of the electric motor 1 and the windings 4.1-4.4 of the starter of said motor. [0003] The fuse is intended to melt when a maximum predetermined current is passed through the motor to cut off power to the motor. This makes it possible to avoid damage to the starter or its surroundings due to heat generated by overcurrent. Such overcurrents occur especially if the rotor of the motor is...
