Magnetic continuously variable transmission

This project describes a continuously variable transmission device, in which torque transmission and variable gear ratio is achieved by magnetic means. It consists of three concentric pulleys: control pulley, input and output pulleys. All three pulleys have number of pole-pairs on the outer surfaces. The output shaft from engine is connected to input pulley. The output pulley is connected to final drive by means of centrifugal clutch. First pulley starts rotating with the help of engine. We use the control pulley to obtain similar direction movement from input pulley to output pulley. By use of this Magnetic CVT we can enhance the overall performance of vehicle. This Magnetic CVT has scope in future or we can say that it is the only option regarding to efficiency problem in automatic transmission vehicle.
