  • Publication number: 20230336045
    Abstract: An electric component for an electric machine includes a body having slots defined therein, and a conductive winding extending out of axial end(s) of the slot(s). The electric component may include any electric machine component having conductive windings, e.g., a stator for a generator. The electric component includes a resin dam around the conductive winding at axial end(s) of the slot(s). The resin dam blocks liquid communication through at least a space between the conductive winding and an inner surface of the slot(s), during manufacture. The electric component also includes a (solidified) insulating resin in the slot(s) and against the resin dam(s) at the axial end(s) of the slot(s). Any number of the conductive windings and slots may include a resin dam, e.g., one, some or all. The resin dams ensure complete filling of the slots and encapsulation of the conductive windings.

  • Patent number: 10658806
    Abstract: A brush holder apparatus has a stationary support member having two opposing grooves, a fork electrical connector, and a conductive bar configured to pass through a portion of a main body of the stationary support member. The conductive bar provides electrical conductivity with a collector mount and the fork electrical connector. A brush holder is configured to be releasably affixed to the stationary support member, and has two rails configured to slide along the grooves. The brush holder has a knife electrical connector configured to mate with the fork electrical connector. A brush spring is clipped on the brush holder, and the brush spring presses a brush against a collector of a dynamoelectric machine. A brush lead is connected to the brush and a brush terminal. The brush lead is an elongate conductive member, and a brush wear indicator is disposed over the brush lead.
