The stator includes salient stator poles positioned on the front surface. Each one of the salient stator poles including: a bobbin protruding out from the front surface in a direction along an axis of the bobbin that is perpendicular to the front surface; the bobbin comprising a bobbin front surface that is substantially parallel to the front surface of the stator; and a coil of electrically insulated wire wound around the bobbin. A rotor includes a front rotor surface and an opposite facing rear rotor surface; and further includes a plurality of rotor poles. The rotor is affixed to a shaft and rotates about an axis of rotation that is aligned with the shaft.

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 method for controlling an electrical power system connected to an electrical grid having a generator and a power converter includes monitoring a speed condition of the electrical power system. The method also includes dynamically determining at least one regulator maximum limit for at least one regulator of the power converter based on the monitored speed condition. Further, the method includes operating the at least one regulator based on the at least one dynamic regulator maximum limit to avoid overmodulation of the electrical power system during high-slip operation and to improve sub-synchronous control interaction (SSCI) performance of the electrical power system.

Abstract: A system including a generator and a controller. The generator includes a permanent magnet generator (PMG), and an exciter. The controller manages operations of the generator. The controller includes an alternating current to direct current (AC-to-DC) converter that generates a direct current (DC) voltage, an exciter drive that provides a DC current to the exciter of the generator using the DC voltage created by the AC-to-DC converter in accordance with the control signal, and a regulator controller that drives the active AC-to-DC converter.

Abstract: A system for load balancing on a multi-phase power line connected to a single phase lateral power line, includes a contactor configured to selectively connect each phase of the multi-phase power line to the single phase lateral power line. There is a phase change device connected in parallel with the contactor and a controller. During the phase change state, the controller connects the input of the phase change device to the multi-phase power line and connects the output of the phase change device the single phase lateral power line. The controller causes the phase change device to output a voltage to the single phase lateral line initially aligned with the first phase and then rotated to align with the second phase and causes the contactor changes connection to the second phase of the multi-phase power line and disconnect the phase change device from the power lines.
