Abstract
A starter-generator system is configured to be operable at multiple variable frequencies. The starter-generator includes a rotor and a stator. The rotor is configured to rotate and has a single main field winding wound thereon. The stator has at least a first stator winding set and second stator winding set independently wound thereon. Upon electrical excitation and rotation of the rotor the starter-generator supplies electrical power from each of the stator winding sets at different frequencies. Also, upon electrically exciting one or both of the stator winding sets with appropriate AC power, the rotor will rotate and generate a starting torque.
