Abstract
A motor includes a stator and a rotor, equipped to be movable in at least a first direction relative to the stator, the rotor operably interfacing the stator so that a motor force is generated in a first direction, where the stator comprises an anti-cogging element configured to generate anti-cogging forces on the rotor in at least the first direction and a second direction at an angle to the first direction.
