Abstract: An electrical machine includes a stator defining a plurality of circumferentially spaced slots. A layered conductor is wound into the slots. The layered conductor includes a plurality of layers wherein at least two adjacent layers in the plurality of layers have electrical conductivities that are different from one another. The at least two adjacent layers can form an interface therebetween that is tangentially aligned with a circumferential direction around the stator. The at least two adjacent layers can be in electrical communication with one another with no intervening insulator therebetween. One of the at least two adjacent layers can include a relatively high electrical conductivity metal, and another one of the at least two adjacent layers can include a relatively low electrical conductivity metal.

Abstract: An aircraft main power generation system includes a rotor shaft, a main power generator a permanent magnet, an exciter, an aircraft power bus, and a generator control unit. The generator control unit is configured to provide a control current to the exciter in response to a speed of the main power generator reaching a threshold speed and electrically couple the main power generator to the aircraft power bus in response to the speed of the main power generator reaching a minimum operating speed, the threshold speed being lower than the minimum operating speed; or provide a control current to the exciter in response to the speed of the main power generator reaching a predetermined speed and electrically coupling the main power generator to the aircraft power bus in response to a time period elapsing after the speed of the main power generator has reached the predetermined speed.

Abstract: A wedge for securing windings in a slot in the rotor poles of a rotor core of an electrical machine includes an elongate wedge body extending in an axial direction along a longitudinal axis. The wedge body includes layers perpendicular to the axial direction. The layers vary in electrical conductivity from layer to layer to inhibit eddy currents within the wedge body.

Abstract: An electrical terminal device adapted to mount to a structure, and including a electrically non-conductive substructure, an electrically non-conductive cover, a heat resistant shroud, and an electric terminal. The substructure is in contact with the structure. The cover is engaged to the substructure. The substructure and the cover define a chamber, and the substructure defines, at least in-part, a sealed passage in communication with the chamber. The heat resistant shroud substantially covers the cover. The cover is substantially located between the shroud and the substructure. The electric terminal is located in the chamber and is attached to the substructure.

Abstract: A disclosed terminal block assembly for a generator includes a terminal block with a base with first and second transverse terminal surfaces adjoining one another. One of the terminal surfaces includes an increased width greater than a length of a cable terminal lug for providing a lightning strike and creepage barrier. The terminal surfaces include spaced apart protrusions extending from the first and second surfaces to provide spaced apart terminal areas overlapping the first and second surfaces. First and second terminal studs are disposed within each corresponding first and second terminal areas and are electrically connected by a bus bar.
