  • Permanent magnet motor
    Patent number: 3935487
    Abstract: A permanent magnet motor which generates mechanical output power by the repulsion forces between a movable permanent magnet and a fixed permanent magnet. A movable magnetic shield is interposed between the magnets when they are adjacent one another and then the shield is moved to expose the fixed magnet as the movable magnet passes by. A second fixed magnet can be added to increase the output power by attracting the movable magnet as it approaches. The movable magnetic shield is interposed between the movable magnet and the second fixed magnet when they are adjacent one another.
