Variable ratio torque converter
First Claim
1. A variable ratio torque converter including an input member for connection to a primary drive, an output member coupled to a torque multiplying member for connection to drive a load, the input member having paired magnet poles, and the output member having a plurality of pairs of movable periphery magnets per pole, and a winding arranged for each peripheral magnet pairs, the windings being connected to a controllable inverter arranged to control torque from the torque multiplying member, the input member and the output member are arranged so that the output member rotates with the input member under magnetic force, the moving peripheral magnets causing the windings to produce a slip related control signal for the inverter to control the torque from the torque multiplying member.

Abstract
Provided is a variable ratio torque converter including an input member for connection to a primary drive, an output member coupled to a torque multiplying member for connection to drive a load. The input member has paired permanent magnet poles, and the output member has a plurality of pairs of movable periphery magnets per pole, and a winding arranged for each peripheral magnet pairs. The windings are connected to a controllable inverter arranged to control torque from the torque multiplying member. The input and output members are arranged so that they rotate together under magnetic force. The peripheral magnets cause the windings to produce a slip related control signal for the inverter to control the torque. The converter may include a slip responsive arrangement for retarding actuation of the peripheral magnets to thereby delay movement when there is a slip between respective speeds of the input and output members.
