Abstract
A stator for a generator includes a ferromagnetic core with two or more poles arranged about a rotation axis, a direct current (DC) field coil, and four or more alternating current (AC) coils. The DC field coil is wrapped about the pole. A first of the AC coils is wrapped about the pole at a location circumferentially spaced from a second of the AC coils. Generator systems and methods self-exciting synchronous reluctance generators are also described.
