摘要
A motor includes a rotor used in conjunction with a stator to produce a magnetic field in the 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 has at least one stator winding configured to form p pole pairs to produce a first magnetic field to rotate the rotor about the axis of rotation and configured to produce a second magnetic field of either one pole pair or p±1 pole pairs to create forces radial to the axis of rotation. The at least one stator winding has two sets of terminals, a first set of 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 second set of terminals for carrying current that produces the 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. The second set of terminals experience no motional-electromotive force when the rotor is centered on the axis of rotation.
