Abstract
Magnetic flux from a plurality of permanent magnets interacts between a drive disc and a driven disc to transmit selected power in infinitely variable ratios from the drive disc to the driven disc. Control means operatively connected between the drive disc and the driven disc position the discs to vary the amount of magnetic flux coupled between the discs, thereby infinitely varying the transmitted power and the speed differential between the input and the output of the transmission. The magnetic flux may be selectively coupled from the driven disc to a stationary brake means to restrict movement of the driven disc and to absorb energy from the output of the transmission.
