摘要： A wedge for a wound rotor includes a wedge body. The wedge body has a first layer and one or more second layers interfused with one another to provide structural support and limit resistive heating of the wedge from current flow within the wedge body by windings spaced apart by the rotor wedge. Generator rotors and methods of making generator rotors are also described.

摘要： Exhaust gases (28) from an engine (16, 16′), input to turbo-compounder (20), drive a bladed turbine rotor (48) therein, which drives a generator (56, 56.1, 56.1′, 126, 126′, 126″), the output of which is used to electrically drive an induction motor (104, 104′), the rotor (106) of which is mechanically coupled to the engine (16, 16′) so as to provide for recovering power to the engine (16, 16′). The turbo-compounder (20) also incorporates a wastegate valve (36, 36′) to provide for the exhaust gases (28) to bypass the bladed turbine rotor (48). Upon startup the wastegate valve (36, 36′) is opened, and the generator may be decoupled from the engine (16, 16′). The generator (56, 56.1, 56.1′, 126, 126′, 126″) may be coupled to the engine (16, 16′) either by closure of a contactor (110, 110′), engagement of an electrically-controlled clutch (124), or by control of either a solid-state switching (125) or control system or an AC excitation signal (130), when the frequency (fGENERATOR) of the generator (56, 56.1, 56.1′, 126, 126′, 126″) meets or exceeds that (fMOTOR) of the induction motor (104, 104′). Wastegate valve (36, 36′) closure provides for the generator (56, 56.1, 56.1′, 126, 126′, 126″) to recover power from the exhaust gases (28).

摘要： A rotor in an electrical machine, the rotor comprises a magnetic core having at least two poles, a plurality of winding assemblies, one for each pole, and a cylindrical tube enclosing the magnetic core and winding assemblies, the tube including a plurality of rings having different axial widths. Each of the rings is axially spaced apart from an adjacent ring. The respective axial widths of the rings become progressively smaller than the axial width of the ring axially located at or near the center of the tube as the axial distance away from the center of the tube increases. A plurality of winding braces are coupled to at least one of the winding assemblies, the winding braces having different radial heights.
