Abstract: A thermal control and keybar voltage differential reduction mechanism is provided for use in a power generator having multiple keybars that are each coupled to a flange. The mechanism includes an electrically conductive coupler capable of being electrically coupled to each of a first keybar and a second keybar of the multiple keybars. The coupler facilitates a flow of a current from the first keybar to the second keybar in response to a rotation of a rotor of the power generator, shunting the current away from the flange and producing a first magnetic field that opposes a second magnetic field induced by the rotation of the rotor.

Abstract: A power generator that operates at a reduced temperature level includes a flux shunt that reduces the amount of fringing magnetic flux axially impinging upon a stator, flange, and multiple keybars during operation of the generator. By reducing the amount of axially impinging flux, the flux shunt reduces an operating temperature of the stator and flange and reduces a voltage differential between keybar voltages induced by the flux in the multiple keybars.

Abstract: A power generator that operates at a reduced keybar voltages and currents, flange currents, and keybar voltage differentials includes a keybar shield that reduces the amount of magnetic flux coupling into a keybar of multiple keybars during operation of the generator. By reducing the amount of coupled flux, the keybar shield reduces a keybar voltage and a keybar current in a keybar, reduces keybar current flowing into a flange, and reduces a voltage differential between voltages induced by the flux in the multiple keybars.

Abstract: A field coil for an electromagnetic rotor comprising multiple windings, each substantially entirely coated with a powder resin having a dielectric strength of at least in the range of 1000-1500 v/mil. A method of manufacturing a field coil for an electromagnetic rotor includes the steps of a) providing a field coil comprising multiple layers of copper bars; b) coating the multiple layers of the field coil with a powder resin having a dielectric strength of at least about 1000-1500 v/mi.; and c) curing the powder resin.
