Abstract
A rotating electrical machine, such as an aircraft starter-generator, includes an exciter that has its stator windings divided into a number of sections. A plurality of switches are electrically coupled to the exciter stator winding sections and are configured and controlled so that the exciter stator winding sections may be selectively coupled in series or in parallel with one another, and selectively coupled to receive either DC or AC power.
