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.
