Abstract
Example brush holder assemblies of an electric machine are disclosed. An example brush holder assembly of an electric machine includes a carbon brush including an upper surface and a lower surface opposite the upper surface. The brush holder assembly also includes one or more lead wires extending out of the carbon brush at an insertion point on the upper surface and a first cavity extending into the carbon brush from the upper surface at a location spaced away from the insertion point of the one or more lead wires and unobstructed by the one or more lead wires.
Claims18
An assembly for a brush holder assembly of an electric machine, comprising:
- a carbon brush including an upper surface and a lower surface opposite the upper surface,
- one or more lead wires extending out of the carbon brush at an insertion point on the upper surface;
- a first cavity extending into the carbon brush from the upper surface at a first location spaced away from the insertion point of the one or more lead wires and unobstructed by the one or more lead wires;
- and
- a second cavity extending into the carbon brush from the upper surface at a second location spaced away from the insertion point of the one or more lead wires and unobstructed by the one or more lead wires;
- wherein the first and second cavities are in a spaced apart relationship to receive first and second projections of a spacer against the upper surface of the carbon brush.
A method of assembling a brush holder assembly of an electrical device, comprising:
- aligning first and second projections of a spacer with first and second cavities in an upper surface of a carbon brush, the carbon brush including one or more lead wires extending out of the carbon brush at an insertion point on the upper surface, wherein the first and second cavities are spaced away from the insertion point;
- inserting the first and second projections into the first and second cavities to releasably attach the spacer to the carbon brush;
- and
- inserting the carbon brush into a brush holder mounted on the electrical device.
