Abstract
An electric motor including a driven element, a magnet assembly and a driving element. The driven element being driven in a direction of movement. The magnet assembly is includes first and second magnets each having first and second magnetic poles. The first magnetic pole of the first magnet and the first magnetic pole of the second magnet being proximate to each other and facing each other thereby defining a first magnetic zone therebetween. The first magnetic poles all being similar, and the second magnetic poles all being similar. The driving element is proximate to the magnet assembly, producing a magnetic field within the driving element that is primarily orthogonal to the direction of movement.
