The invention relates mainly to an assembly comprising a brush cage and a spiral spring (), the spiral spring () comprising an axis (Y), a wound part () wound about the axis (Y) and an arm () extending from one end of the wound part (), the brush cage comprising at least one lateral wall provided with an opening for the passage of the arm () through the lateral wall so that one end of the arm () can press against at least part of an end face of a brush, wherein the arm () comprises a first portion () of which the width (L) measured along the axis (Y) is different from the width (L) of the wound part () measured along the axis (Y) of the spiral spring ().

Assembly comprising brush cage and spiral spring, and corresponding brush-holder, electric motor and motor vehicle starter

The invention relates mainly to a brush cage () for a brush holder () of an electric motor comprising:&#x2014;two lateral walls () and a connecting wall () connecting the two lateral walls (),&#x2014;in which cage at least one of the lateral walls () has an opening () for the passage of a spring arm,&#x2014;the lateral wall () comprising the opening () having a length (L) measured between a first end () intended to be furthest from a commutator and a second end () intended to be closest to the commutator, wherein the opening () comprises at least a first portion () between the two ends () which widens out towards the second end ().

Brush cage for motor vehicle starter, and corresponding brush holder, electric motor and motor vehicle starter

Brush holder support plate () for an electric engine comprises a central through-hole () for the engine manifold and guide elements () for receiving brush holders () in sliding connection on the plate. The plate allows the brush holder to be mounted on the plate, engaging same in the direction running from the edge () of the plate towards the central through-hole (). The plate comprises a non-return stop () for each brush holder () after the latter has been mounted in sliding connection on the plate, the stop being elastically retractable. The brush holders () have a base shaped so as to be received in sliding connection in the guide elements () of the plate (). They have a recess in the base of same suitable for being engaged by the corresponding non-return stop () of the plate ().

Brush-holder support plate for electric motor, and corresponding brush-holder

A brush-holder for a motor vehicle starter comprising at least one first electrically conductive cage receiving a first brush having a first polarity, at least one second cage receiving a second brush having a second polarity different to the first polarity, at least one support plate on which the first cage and the second cage are attached, the support plate being electrically connected to the second polarity, and a deformable heat-sensitive member that is deformable from a pre-defined temperature, wherein the deformable member is arranged so as to electrically insulate the first cage relative to the support plate and wherein it further comprises a means for moving the first cage or the support plate in such a way as to establish contact between the first cage and the support plate following a deformation of the deformable member.

Brush-holder for a motor vehicle starter provided with a thermal protection system, and corresponding motor vehicle starter

A brush box () for a brush-holder, which is useful as a housing for an electric machine brush (). The brush box () comprises a lower portion () for guiding the brush, connected to a mounting (), and an upper portion () for guiding the brush, the lower () and upper () guiding portions being open on the side of a front surface () and a rear surface of the brush (). The lower () and upper () guiding portions are separated from one another by a space () enabling a braid of the brush () to pass through.

Brush box for electric machine brush-holder and corresponding brush-holder

A rotating electric machine including at least a first terminal and a second terminal, and an electric circuit connected to said two terminals, the electric circuit including a field winding. The rotating electric machine also includes a thermal protection device () arranged in the electric machine. The thermal protection device () includes a first electric conductor () electrically connected to the second terminal, and a heat-sensitive member () arranged so as to deform above a predetermined temperature, wherein, above a predetermined temperature, the deformation of the heat-sensitive member () actuates a connection means () of the thermal protection device in order to electrically connect the first conductor to a second conductor of the electric circuit having a different electric potential than that of the second terminal.
