摘要： A turbomachine includes a motor including a rotor assembly and a stator assembly. A sleeve fluidly separates the rotor assembly from the stator assembly. The sleeve has first and second ends axially spaced from one another. In one example, first and second seals are arranged at the first end and fluidly separate the rotor assembly from the stator assembly. The second seal is arranged downstream from the first seal relative to the rotor assembly. In another example, the sleeve includes wet and dry sides. A first seal is arranged at the first end on the wet side. A drain is provided in the housing and arranged in a region downstream from the first seal. The drain fluidly connects the region to an exterior of the housing.

摘要： A switched reluctance starter/generator is presented which has a stator mounted within a housing having an outer periphery and a plurality of salient poles defining an inner periphery, the salient poles further defining slots therebetween. A stator cooling sleeve is press fit on the outer periphery of the stator and defines a plurality of cooling channels between the outer periphery of the stator cooling sleeve and the housing. A plurality of phase windings are wound on the plurality of salient stator 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-tailed retaining member, and two opposing wedge shaped expanders. A rotor assembly is rotatably positioned within the stator, and comprises a hollow shaft assembly and a rotor core having a plurality of salient poles press fit on the outer periphery of the shaft. The hollow shaft assembly comprises an outer sleeve and an inner cooling sleeve. 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 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, and are coupled to external sources of cooling fluid and electrical energy by electrical/hydraulic terminal connectors.

摘要： A power generation system and method uses a constant frequency generator to generate electrical power in a generate mode. When operating in a start mode, the constant frequency generator is controlled by a motor controller which at least partially controls another component while the system is in a generate mode. The power generation system and method can be implemented in, for example, an aircraft electrical architecture.

摘要： A bypass valve assembly for a generator includes a spring cover with a flange which extends in a radial direction from a spring cover body. The spring cover body defines an overall length dimension, the overall length dimension to an end of the spring cover body to the flange dimension defines a ratio between 1.6:1-1.2:1. The bypass valve assembly also includes a valve sleeve with a multiple of windows. Each of the multiple of windows includes a longitudinal edge which defines a longitudinal edge radius and corner radius.
