ABSTRACT:
A rotating electrical machine, such as an aircraft starter-generator, that may be operated in either a DC motor mode or an AC generator mode. The machine includes a main stator that is selectively configurable as a multi-pole AC stator and a multi-pole DC stator. The machine also includes DC brushes that are selectively moveable into, and out of, electrical contact the main rotor, to thereby electrically couple and decouple a DC power source to and from, respectively, the rotor windings.
