Abstract: Systems, methods and apparatus for winding conductive wires for a stator of an electric motor. In one embodiment, a hysteretic tensioning apparatus is utilizing to substantially stabilize tension in a conductive wire supplied to a winding machine. The hysteretic tensioning apparatus includes a support member, a brake member, and four idler arms. The brake member is rotatably mounted to the brake member and configured to engage the conductive wire. The idler arms each are spring mounted to the support member and also are configured to engage the conductive wire. The conductive wire is extended across the support member so that it extends between adjacent idler arms and the brake and is inserted into the winding machine.

Abstract: An electromagnetic device of significantly reduced size is provided by the specific designs of the end shields of the device and by the specific designs of insulating end caps of the device that insulate the electrical component parts of the device from contact and possible shorting with mechanical structural parts of the device.

Abstract: A drive package for a dynamoelectric machine mounts a printed wire board in cantilever fashion from a wall of a drive package housing. Potting material in the housing provides mechanical support for the printed wire board away from the heat sink. Heat generating components on the first printed wire board have tubes of electrically insulating, thermally conductive material inserted over them and are clamped against the heat sink. The heat sink is mounted directly to the housing and is electrically grounded by the housing.
