摘要： An endshield assembly for an electronically commutated motor includes an endshield, a control assembly, and a power assembly. The endshield includes a plurality of recessed fins on an outer surface, and a substantially flat raised portion on an internal surface. The raised portion is in contact with a thermal pad. The control assembly includes the thermal pad and a control board on which is located a plurality of power transistors. The thermal pad provides thermal contact between the transistors and the endshield to enable the endshield to dissipate heat from the transistors. The transistors include a plurality of leads that extend substantially parallel to the control board which enable the leads to be coated for protection against harsh external environments. The power assembly includes a power board having an insulator positioned between the power board and the control board.

摘要： A dynamoelectric machine having a wire retaining device constructed to frictionally retain the quadrature winding to allow automated winding of the quadrature winding. The wire retaining device includes stator end caps having integrally formed wire retention elements at the radially inner end of the stator tooth. The wire retaining device frictionally holds the wire in place as the quadrature winding is automatically wound about the stator. In addition, the stator end caps electrically insulate the quadrature winding from the stator and the main winding.
