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: A rotor of a generator includes a plurality of permanent magnets and at least one magnetic band. The plurality of permanent magnets is arranged about an axis such that magnetic poles of the plurality of permanent magnets are radially oriented in regard to the rotor. The at least one magnetic band is disposed on a surface of the rotor such that magnetic poles of the magnetic band are between 1 degree and 90 degrees from being axially oriented in regard to the rotor.

Abstract: An electric machine assembly includes a rotor core. The rotor core includes a plurality of winding poles extending between a first axial face and a second axial face of the rotor core. A clench lock slot is defined in the first axial face. The clench lock slot includes a first channel section having a first channel width, a second channel section having a width equal to the first channel width, and a converging-diverging section connecting between the first channel section and the second channel section. A first end of the converging-diverging section connects to the first channel section and has a width equal to the first channel width. A second end of the converging-diverging section connects to the second channel section and has a width equal to the first channel width. A clench point of the converging-diverging section is defined where the converging-diverging section is narrowest.

Abstract: A permanent magnet generator (PMG) system can include a stator configured to output a voltage, and a rotor assembly configured to be magnetically coupled to the stator and to rotate relative to the stator to induce the voltage. The rotor assembly can be configured to passively attenuate the voltage output from the stator in response to acceleration of the rotor assembly at or above an impulse acceleration threshold.

Abstract: An assembly comprises a resistor plate for a rotating rectifier assembly (RRA). A shaft bore is defined through the resistor plate for passage of a shaft of an electrical machine, and the resistor plate defines a main annular body around the shaft bore. A first protrusion extends radially outward from the main annular body, so that a first pin bore extends through the first protrusion. At least one contact band is seated in a the pin bore of the resistor plate for mounting a direct current (DC) pin to the resistor plate.

Abstract: A main field connection to connect to a main field winding has a semi-cylindrical portion with an axially thicker outer surface, an axially thinner inner surface, with an aperture. An extending portion extends from the semi-cylindrical portion to a remote extending end. The remote extending end extends for a first axial distance. The axially thicker portion of the semi-cylindrical portion extends for a second axial distance. A ratio of the first axial distance to the second axial distance is between 0.65 and 1.4. A rotating assembly, a generator and a method are also disclosed.

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.
