  • Patent number: 8076813
    Abstract: A hermetic motor includes a stator having at least one winding formed by a winding wire, and an on-winding motor protector having at least one contact. To improve the reliability and reduce the cost of the hermetic motor, the winding wire is directly coupled (without a lead wire) to the motor protector contact. Additionally, a common wire extending from the motor protector to a cluster block (if applicable) can be the same type of wire as the winding wire.

  • Patent number: 7527530
    Abstract: An electric terminal connector block is provided with oblong tool openings that communicate with interior channels of the connector block and with openings in the motor wiring electric terminals positioned in each channel of the connector block. The oblong shapes of the tool openings enable insertion of tool pins through the tool openings and openings of the electric terminals and movement of the tool pins along the lengths of the oblong tool openings whereby the tool pins engage with the electric terminals and move the terminals relative to the connector block to insure that the terminals are locked in place in the connector block. In addition, the tooling used with the connector block is operated according to a method that insures that the terminals of the motor winding are moved to a position relative to the connector block where the terminals are locked in place.

  • Patent number: 7066774
    Abstract: An electrical connector includes a terminal attached to a length of wiring that extends from the stator windings of an electrical device, and a tubular insulating sleeve that extends along the length of wiring. The sleeve is secured stationary relative to both the wiring and the terminal by being secured to the stator windings by the same mechanical connection that binds the stator windings.
