Abstract
A starter-generator system is configured to supply power to an aircraft electrical bus having a rated AC voltage magnitude, or receive power from a start converter, and includes a rotor and a stator. The stator is disposed at least partially around at least a portion of the rotor and has at least one multi-phase stator winding set wound thereon that has an increased number of turns per phase that is greater than a least number of turns per phase needed to supply power to an aircraft electrical bus at the rated AC voltage magnitude. The increased number of stator turns results in reduced current drawn by the starter-generator during the motor mode, which improves the efficiency and introduces other benefits to the overall starting system.
