Abstract
A reluctance machine system including a reluctance machine having a rotor, a stator and fully-pitched windings and a drive, wherein the drive energizes the phase windings such that continuous uni-polar current is provided to at least one of the phase windings and bi-polar current is applied to other phase windings to provide output torque as a function of the mutual-inductance between the energized phase windings. Also, a method of operating a fully-pitched reluctance machine according to the described energization scheme.
