Abstract

An electric motor including: a hub assembly defining a rotational axis; a magnetic rotor assembly; a first coil stator assembly; a second coil stator assembly; and a system of rotor bearings rotatably supporting each of the magnetic rotor assembly, the first coil stator assembly, and the second coil stator assembly on the hub assembly so that each of the magnetic rotor assembly, the first coil stator assembly, and the second coil stator assembly are rotatable about the rotational axis independently of each other.
