Abstract
A reluctance machine including a stator defining a plurality of stator poles and a plurality of stator slots, a rotor positioned to rotate with respect to the stator, and a plurality of phase windings, where each phase winding comprises a plurality of coils, where each coil is wound about more than one stator pole, where each coil comprises two coils sides, and where only one coil side is positioned in each stator slot, wherein the self-inductance of each phase winding varies as a function of the angular position of the rotor with respect to the stator. Also a reluctance machine similar to that described above where each of the phase windings is magnetic uni-polar.
