Abstract: A switched reluctance starter/generator (100) is presented which has a stator (102) mounted within a housing (104) having an outer periphery and a plurality of salient poles (130) defining an inner periphery, the salient poles further defining slots (134) therebetween. A stator cooling sleeve (136) is press fit on the outer periphery of the stator and defines a plurality of cooling channels (126) between the outer periphery of the stator and the housing. A plurality of phase windings (110) are wound on the plurality of salient poles, and phase winding retainers are positioned within the slots for securing the phase windings on the salient stator poles. The winding retainers comprise a triangular base separator, a quasi-dove-tail retaining member, and two opposing wedge shaped expanders. A rotor assembly (168) is rotatably positioned within the stator, and comprises a hollow shaft assembly (118) and a rotor core (116) having a plurality of salient poles (138) press fit on the outer periphery of the shaft. The hollow shaft assembly comprises an outer sleeve (144) and an inner cooling sleeve (142). The inner periphery of the inner cooling sleeve defines an interior void of the shaft. The outer periphery of the inner cooling sleeve is press fit on the inner periphery of the outer sleeve and defines a plurality of cooling channels (150) between the inner periphery of the outer sleeve and the outer periphery of the inner cooling sleeve. The stator windings are wound from hollow core conductors (152), and are coupled to external sources of cooling fluid and electrical energy by electrical/hydraulic terminal connectors.
