Abstract: An electric machine rotor assembly includes a rotor core defining a rotor axis. Windings are seated in the rotor core. A plurality of wedges circumferentially spaced apart around the rotor core relative to the rotor axis. Each rotor core extends axially and separates between two respective portions of the windings. A supply end plate is mounted at a first axial end of the rotor core. A return end plate is mounted at a second axial end of the rotor core opposite the first axial end. A flow path for coolant fluid extends through the supply end plate into the wedges, through the wedges and into the return end plate, and through the return end plate.

Abstract: A generator including a stator winding, a rotor positioned radially inside the stator winding, including multiple coil assemblies each using a flat wire, a primary termination plate residing radially inside the rotor configured to connect a wire of a coil assembly to an adjacent wound coil and a secondary termination plate residing radially inside the rotor configured to connect a wound coil to an adjacent wound coil and connect the wound coil to a terminus connection.

Abstract: A generator includes a stator with a stator winding, a rotor with a field winding supported for rotation relative to the stator, and a housing enclosing the stator and the rotor. The housing has an independent system port that is connected to a shared system port by a selector. The selector fluidly couples the stator and one of the independent system port and the shared system port. The selector also fluidly separates the stator from the other of the independent system port and the shared system port. Generator arrangements and methods of making generators are also described.

Abstract: A supply end plate apparatus includes a supply end plate with an aperture therethrough configured to be mounted at a first axial end of the rotor core for supplying fluid to the rotor core. The supply end plate defines a plurality of end plate passages therein extending outward from an inward portion of the supply end plate toward an outward portion of the supply end plate. Each of the plurality of end plate passages includes: a radial section extending in a radial direction from an inlet in the inward portion of the supply end plate toward the outward portion; a transition section extending obliquely from the radial section; and a circumferential section extending circumferentially from the transition section to an outlet of the supply end plate.
