Abstract
A motor includes a coil and a rotor plate positioned proximate to the coil. Magnets are affixed on the side of the rotor plate and arranged in a circle such that, upon rotation of the rotor plate, the magnets pass, successively, adjacent the coil. Each of the magnets is oriented in a plane that extends through each of the magnets from the north pole to the south pole thereof. The magnets include at least a first magnet, a second magnet, and a third magnet. The second magnet is adjacent the first magnet, and the third magnet is adjacent the first magnet. The north pole of the first magnet is spaced a predetermined distance from the south pole of the third magnet, and the south pole of the first magnet is spaced the predetermined distance from the north pole of the second magnet.
