ABSTRACT:
A rotor for an electrical machine according to one embodiment of the present invention comprises a shaft defining an axis of rotation of the rotor, and first and second pole pieces affixed to the shaft for rotation therewith and together defining an interior cavity. The rotor additionally includes a slip ring affixed to the shaft for rotation therewith. Further, the rotor comprises a field-generating coil disposed within the interior cavity, the coil comprising a plurality of turns of electrical wire, the electrical wire further having a section extending to and electrically coupled to the slip ring. Also, the rotor has a retainer disposed exterior to the cavity and adjacent the first pole piece, the retainer comprising a radially-extending channel containing a portion of the section of electrical wire.
