Abstract
The electric machine includes a collector (60), a brush-holder assembly comprising an end cap (26) and a set of members (28, 30, 32, 34) for electrical connection equipped with guide cages (36, 38, 40, 42) suitable for accommodating a respective brush (44), in which a member (64) for limiting the radial displacement of the brushes in the absence of a collector is provided, the dimensions of the limiting member (64) being suitable for obtaining a tight fit of this member on the end cap (26). Application for the mounting of a brush holder for a motor-vehicle starter.
Claims13
Electric machine including a collector (60) integral with an armature shaft (62), a brush-holder assembly comprising an end cap (26) forming a bearing intended to be mounted on a carcass of the machine and a set of members (28, 30, 32, 34) for electrical connection of the brushes mounted on the end cap (26), in which some of the members for electrical connection of the said brushes are composed of guide cages (36, 38, 40, 42) suitable for accommodating a respective brush (44);
- the said guide cages being provided internally with elastic means (45) pushing the brushes, in operation, radially into abutment against the collector (60) of the electric machine, and in which a member (64), called limiting member, forming an abutment for limiting the radial displacement of the brushes in the absence of a collector is provided, characterised in that the dimensions of the limiting member (64) are suitable for obtaining a tight fit of this member on the end cap (26).
