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 method of cooling a shaft of a gas turbine engine includes moving a control valve towards a position that inhibits fluid flow from a high pressure air source to an air turbine starter and enables fluid flow from a blower motor to the air turbine starter, in response to a gas turbine engine shutdown. The method further includes operating the blower motor to provide air to the air turbine starter.

Abstract: A multi-rotor electric machine includes a first rotor, a stator, and a second rotor. The stator is disposed concentric with the first rotor and is disposed radially outward from the first rotor. The stator has a first plurality estate or windings disposed proximate first stator teeth of the stator. The stator has a second plurality of stator windings disposed proximate second stator teeth of the stator. The second rotor is disposed concentric with and is disposed radially outward from the stator. The second rotor is rotatable relative to the first rotor.

Abstract: A pole separator insert is employed in a stator assembly of an electric machine to separate winding coils installed within circumferentially distributed slots of a stator core. The pole separator insert comprises first and second insulating tabs connected by first and second legs. The first and second insulating tabs are disposed between adjacent winding coils of a single phase, at opposite ends of the stator core. The first and second legs are disposed through adjacent circumferentially distributed slots of the stator core.

Abstract: A stator core is provided and includes laminations disposed in a laminated arrangement to form a stator core body having an axial length extending in a lamination dimension. The stator core body includes an annular portion extending along the axial length and teeth extending radially from the annular portion and along the axial length. Each tooth has a trapezoidal shape and is formed to define one or more triangular holes running along the axial length.

Abstract: A core for an electric machine includes a core body with a tooth arranged along a rotation axis, a winding with a flat wire coil fixed to the core body and seated on the tooth of the core body, and a flat wire jumper. The flat wire jumper is supported by the core body and is connected to the flat wire coil to place the flat wire coil in electrical communication with flat wire coils of the winding. Methods of making cores with flat wire jumpers and generators having cores with flat wire jumpers are also described.

Abstract: A machine includes a rotor and a stator that is situated adjacent the rotor. The stator includes a plurality of wire-wound phases. The phases include at least first and second wire-wound phases that differ in temperature-responsive electrical resistance. A controller is in electrical communication with the stator. The controller is configured to identify an over-temperature condition of the stator based upon the differing temperature-responsive electrical resistance and modify the operation of the stator in response to the over-temperature condition.
