Abstract
A doubly fed brushless induction starter generator includes a stator and a rotor, which are separated by an air gap. The stator includes stator winding slots, each of which includes a first layer of power windings, a second layer of power windings, and a third layer of control windings, which include 2-pole single-phase windings. The control windings are arranged in the stator winding slots between the air gap and the first and second layers of power windings. Direct current is delivered to control windings in the generator as an excitation current to thereby produce a magnetic flux, through which the stator is moved to produce and alternating current in the power windings as an output current. The output current can be delivered to an electrical load, such as an electrical component on an aircraft.
