Brush assembly for an electric motor |
摘要 |
An electric motor is provided including: a stator, an armature rotatably received within the stator and having an armature shaft on which a commutator is mounted, and a brush assembly. The brush assembly defines a first surface facing the stator and a second surface opposite the first surface. The brush assembly includes a brush card mount, brushes in sliding contact with the commutator to supply electric current to the commutator, and thermally-conductive brush holders disposed on the second surface of the brush assembly to house the brushes and secured to the brush card mount. Each brush holder includes projections formed along a length of an outer surface of the brush holder to increase a total surface area of the brush holder and transfer heat away from the brush holder. |
