Abstract: A generator includes a stator with a stator winding, a rotor core with a rotor tooth supported for rotation relative to the stator about a rotation axis, and a field winding. The field winding includes a field coil that is seated on the rotor tooth. The field coil includes two or more flat wire turns stacked with one another and formed such edges of the field coil tightly engage circumferential faces of the tooth. Electrical systems and methods of making generators are also described.

Abstract: A rotating resistor assembly for use in a rotating shaft of an electrical machine can include a first housing configured to contact the rotating shaft and be grounded to the rotating shaft. The first housing can include a first bus bar connection aperture configured to receive a first bus bar. The assembly can include a second housing configured to connect to the first housing. The second housing can be configured to be insulated from the rotating shaft and to be insulated from direct electrical connection with the first housing. The second housing can include a second bus bar connection aperture configured to receive a second bus bar. The assembly can include a suppression resistor disposed between the first housing and the second housing and in electrical communication with the first housing and the second housing to provide an electrical pathway between first housing and the second housing.

Abstract: A variable frequency generator (VFG) rotor can include a plurality of windings configured to form a plurality of magnetic poles, each winding comprising a first winding end and a second winding end, and a first winding support structure comprising a plurality of first winding support segments configured to retain a first portion of each winding, each winding support segment being configured to move radially relative to an axis of rotation of the rotor. The first winding end of each winding extends from each winding support segment. The rotor can include at least one flexible bus bar jumper connected to two first winding ends of adjacent windings and configured to flex with radial movement of the winding support segments of respective windings attached to the flexible bus bar jumper.

Abstract: A rotor for an electrical machine includes a rotor core having a plurality of circumferentially spaced apart rotor poles. A plurality of windings are seated in gaps between circumferentially adjacent pairs of the rotor poles. A respective wedge secures the windings in each gap configured to supply Q-axis damping. A pair of end plates are connected electrically to the wedges at opposing longitudinal ends thereof thereby completing a Q-axis winding circuit for each wedge.

Abstract: A brushless, three phase wound field synchronous machine (WFSM) provides an electromechanical power transfer system wherein it may serve as both a starter and a generator. Power for the excitation system of the WFSM is provided by a three phase flux switching generator (FSG). The three phase FSG also provides position sensor functionality for the WFSM when the WFSM operates in the starter/motor mode.
