Dual purpose no voltage winding design for bearingless AC homopolar and consequent pole motors and an AC homopolar flywheel energy storage system

A motor comprising:

• a rotor used in conjunction with a stator to produce a magnetic field in an air gap having p pole pairs, wherein a single cross section of the rotor taken orthogonal to an axis of rotation comprises iron having a structure forming p teeth,
• the stator having multiple dual purpose stator windings, each stator winding comprising suspension windings and torque windings formed from a single set of coils, each stator winding configured to form p pole pairs to produce a first magnetic field from the associated torque windings to rotate the rotor about the axis of rotation and configured to produce a second magnetic field from the associated suspension winding of either one pole pair or p±1 pole pairs to create forces radial to the axis of rotation,
• each stator winding having two sets of terminals comprising a set of first terminals for carrying current that produces the first magnetic field in the air gap having p pole pairs to rotate the rotor about the axis of rotation and a set of second terminals for carrying current that produces the associated second magnetic field in the air gap having either one pole pair or p±1 pole pairs to create the forces radial to the axis of rotation, wherein p is an integer greater than or equal to two, and wherein the set of second terminals experience no motional-electromotive force when the rotor is centered on the axis of rotation.
