  • Permanent magnet coupling and transmission
    Patent number: 5477093
    Abstract: A magnetic coupler has a magnetic disc containing permanent magnets located between two electroconductive plates and separated therefrom by air gaps. The magnetic disc and electroconductive plates are mounted on coaxial or parallel-spaced input and output shafts so that rotation of the input shaft causes rotation of the output shaft by way of magnetic friction between the permanent magnets and the electroconductive plates.

  • Permanent magnet braking system for drive shafts
    Patent number: 5473209
    Abstract: A braking system adapted to be used on the drive shaft of a vehicle has a rotor containing permanent magnets mounted on the shaft and preferably has a pair of non-rotary electroconductive plates separated by air gaps from the rotor on opposite sides thereof. The plates are slide mounted in a controlled manner on the vehicle chassis to vary the air gaps between brake-on (relatively narrow gap) and brake-off (relatively wide gap) positions.
