Abstract: The present invention relates to a a unipolar current electrical machine operable as a switched reluctance motor, comprising a motor structure and a control unit. The motor structure comprises a plurality of disk-shaped annular stator elements stacked and spaced equidistantly from each other and mounted on a frame; a plurality of disk-shaped rotor elements mounted on a rotational axis and spaced equidistantly from each other such that successive rotor elements are positioned between successive stator elements; a plurality of electrical windings on each of the stator elements, which when energized with a current flow, produce a magnetic field in a direction substantially parallel to the axis; and a return path for completing a magnetic flux path in a second direction perpendicular to the first direction on successive stator elements and through the rotor elements for generating a rotational force in the rotor elements; and a rotor position sensor. A rotor position sensor provides a signal to the control unit.
