Abstract
A reluctance machine system including a reluctance machine having a rotor and a stator including at least one phase winding and a full pitch auxiliary filed winding where constant currents are established in the auxiliary field winding to assist in the establishment of a magnetic field in the machine so as to improve the machine's performance. Alternate embodiments are disclosed wherein the auxiliary field winding is positioned in a conventionally-shaped stator with phase windings of different types (e.g., short-pitched and fractional-pitched).
