Abstract
A motor brush assembly comprises a stamped and formed lead frame including electrical terminals at spaced locations and a dielectric housing member secured onto the lead frame with the electrical terminals being exposed and accessible for electrical termination to electrical power wires and lead wires of capacitors and inductors. Cavities are located in the housing member in which the inductors are disposed. Metal brush holders are positioned in brush holder locations on the housing member and lugs thereof are electrically stapled onto the lead frame. Openings are located in the housing member exposing severable sections of the lead frame separating the lead frame into separate brush circuits. If inductors are to be disposed in the circuit path between the terminated power leads and the brush holder locations, the respective severable sections are also severed which interconnect the lead frame between the associated pairs of terminals corresponding to each inductor. A ground terminal extends outwardly from the housing member.
