Abstract
A motor includes an armature, a coil, and a magnetic support structure. The motor also includes at least one magnet that defines a space. The coil forms a tunnel. The space is defined by the at least one magnet being aligned with the tunnel formed by the coil. Portions of the armature extend through the space and the tunnel. An opening at an end of the coil is shaped so as to restrict movement of the armature.
