Abstract: The invention relates mainly to a starter for a heat engine of a motor vehicle comprising: at least one electromagnetic switch comprising a positive output terminal, at least one electric motor, said electric motor comprising: a stator comprising coils, each of the coils being wound around a pole piece to form a pole, at least one brush cage (43), at least one positive brush (35) mounted in said brush cage, an electrical path between said positive brush (35) and the positive output terminal (32), and at least one thermal protection (96) located in said electrical path, in which said thermal protection is able to disconnect said two elements (93, 95) when the thermal protection has a temperature above a temperature threshold for electrically disconnecting said positive output terminal with respect to said positive brush (35).

Abstract: Starter (1), in particular for a motor vehicle, comprising:—a casing (3);—a rear bearing (5) secured to a rear end of the N casing (3);—a seal between the rear bearing (5) and the casing (3); the starter (1) further comprising:—a lateral opening along the outer periphery (32) of the casing (3);—a grommet (37), mounted in the lateral opening, for leading electric wires, which supply power to the starter (1), through the casing (3).

Abstract: The invention mainly concerns a brush holder (10) for an electric motor, in particular the starter motor of a motor vehicle, comprising guide cages (13) for receiving the brushes (15) and a support plate (12) on which the guide cages (13) are positioned. The guide cages (13) are made from an insulating material. The brush holder (10) comprises legs (29) fixed on the support plate (12), around each of which a spiral spring (24) is intended to be mounted in order to exert a force on the brush (15) in such a way as to press the brush (15) against a collector.

Abstract: The front bearing (110) of a heat engine starter having an output pinion starter drive (120) comprises, in the front, a transverse wall (111) having an opening (112), for passing a body (122) of the starter drive (120) there through, and a cavity (200) for mounting a sealing joint (240). The cavity is set up on the inner periphery of the rear surface (400) of the front bearing. The rear surface is configured so as to form a bearing abutment for the outer ring (231) of a rolling bearing (230) and moreover has at least one hollowed-out area (300) intended to be filled with grease so as to form a grease supply. The hollowed-out area is mostly set up outside the cavity. A heat engine starter having an output pinion is characterized in that it comprises one such front bearing.

Abstract: The invention relates to a method of mounting a retaining ring (21) on a rotating electric armature shaft. The inventive method consists in first mounting the retaining ring (21) on an axial shaft segment (27) which is located in an accessible mounting area between the groove (23) and the splines (15) of the starter drive assembly (10) and, subsequently, moving the starter drive assembly (10) axially towards the rest position such as to move the retaining ring (21) along the aforementioned shaft segment (27) as far as the positioning groove (23) comprising a service area with no radial access.

Abstract: The invention relates to a starter comprising an electric engine (11) which is connected to a starter drive assembly (30) with a planetary gear speed reducer (45) inserted therebetween. According to the invention, the reducer is housed inside a fixed ring gear (46) which comprises a centering (73) having a first support face (70) which is located in the same plane as the connection interface between the support (16) and the cylinder head (15). The invention is suitable for a motor vehicle starter.
