Abstract
A bi-polar hybrid stepper motor includes a stator having a primary winding. The stator and the primary winding are positioned within a housing. A rotor has a magnetic component. The rotor is rotationally operable relative to the stator. An axial coil assembly is positioned within the housing and located proximate ends of the rotor and having a secondary winding. At least a portion of the magnetic component of the rotor is produced by the axial coil assembly in an energized state. The energized state produces an electromagnetic communication between the rotor and the stator.
