A plurality of permanent magnets are arranged to have spaced apart alternating opposite poles at the peripheral of the rotor. A stator magnet alternately attracts the first pole and repels the second pole of each sequential permanent magnet to cause rotation of the rotor. During the interval in which the stator magnet is intermediate to the poles of a given rotor magnet, the force of the stator magnet is nullified.
