A motor core is enclosed within an open-ended cylindrical, distortable flexispline. At rest, the space between flexispline and core is constant. The core has a hub and spoke configuration, with coils fitted to the spokes and connected in pairs, such that opposing pairs of coils are in series bucking relationships. Additional coils can be used, connected in a non-bucking manner, to increase the magnetic flux produced. The flexispline includes a flexible ring gear near the open end. When magnetically attracted, the ring gear distorts to form a multi-lobe shape. The lobes contact a ring gear mounted on a rotating hub. The lobes may also contact the surface of the core. As the magnetic force rotates, the distorted shape rotates, but the flexispline itself does not. The number of teeth on the ring gear and the flexible gear are different, causing the hub to rotate at reduced speed and increased torque.
