ABSTRACT:
The stator electromagnets (80', 82', 84', 86', 88', 90') face inward about the rotor cavity (12) of the motor. Spaced horseshoe magnets (70) with spaced apart, opposite poles face outward about the periphery (22) of the rotor (20). The stator electromagnets are in two arrays. Each array is aligned with one pole of the rotor set of horseshoe magnets and has a pulling electromagnet (80' or 86') of a pole opposite to the pole of the rotor magnet. Each array also includes two pushing electromagnets (82', 84' or 88', 90') circumferentially offset from the pulling electromagnet, which are of a magnetic pole the same as the pole of the rotor magnet. Optical sensors (173, 175), which are axially aligned with the electromagnets, sense the position of rotor with regard to points on the stator. Switches on a circuit card associated with each array of electromagnets connect to the corresponding optical sensor for alternatively passing or blocking current to the electromagnets. The switches energize and de-energize the pulling and pushing electromagnet when the rotor magnet passes an adjacent, preceding, pulling electromagnets when the rotor magnet passes a predetermined position.
