Carbon brush boxes extend motor life

QUALITY CARBON BRUSH BOXES EXTEND MOTOR LIFE

Carbon brushes are one of the least costly parts in an electronic motor. On the other hand, they usually are the critical part when it comes to delivering a lifetime of durability and performance to the motor they are used in. To achieve optimal performance of the carbon brush, a complicated brush box is needed. The traditional high brass brush box guides the brush so it can conduct current between stationary wires and the rotating shaft.

ETCO is able to control the tight tolerances of .002″ across critical formed surfaces, add base extrusions eliminating rivets, all in a high-speed progressive die. This high speed forming dramatically reduces the per part price while maintaining the critical dimensions demanded by the brush box & motor industry.
