More electric engine with regulated permanent magnet machines

摘要

A generator and associated power supply system has a prime mover for driving a shaft to rotate. A pair of permanent magnets is associated with the rotating shaft. A first stator winding is associated with a first of said permanent magnets, with a customer DC bus for providing a first relatively low voltage to the customer DC bus. A second of said permanent magnets is associated with a second stator winding, and an engine accessory DC bus. The engine accessory DC bus provides power to a motor controller and associated accessory motors associated with the prime mover. The engine accessory DC bus is provided with a second relatively high voltage from the second stator winding.
