An electromagnetic motor comprising an inner stator comprising a plurality of stator teeth, each surrounded by one or more turns of electrical wire, a controller which generates a set of currents that are applied to phase windings of the inner stator to generate a pattern of magnetic poles spaced around the inner stator, the spacing between the magnetic poles being larger than the spacing between adjacent teeth of the inner stator, an outer stator that is concentric with the inner stator and comprises an alternating set of magnet poles, the spacing between adjacent magnet poles being smaller than the spacing of the magnetic poles of a first array created by the controller, and an intermediate rotor part that is located between the inner stator and the outer stator and comprises an array of pole pieces, in which the pole pieces of the intermediate rotor part shape a magnetic flux acting between the inner and outer stators, and whereby in use the controller is arranged to control a torque applied to the rotor part by moving the pattern of magnetic poles of the inner stator around an axis of a torque generator.
