Brush-holder device for e.g. electric starter of heat engine, has support including opening provided for passage of armature shaft of machine, and electrically conducting element connected to voltage source and placed in opening of support

摘要

The device (10) has a support (12) mechanically connected to a rotating electrical machine e.g. electric starter, and including an opening that is provided for passage of an armature shaft of the machine. An electrically conducting element (14) connected to a voltage source is placed in the opening of the support. Two half-plates (16A, 16B) mechanically connects the element to the support. Cages are integrated to the support for receiving two pairs of brushes. The brushes cooperate with a commutator, and a rear bearing has a hollow shape.
