Prototype of electromagnetic actuator for continuously variable transmission for passenger car

Continuously variable transmission (CVT) system transmits the engine /battery power to the car driving wheel smoothly and efficiently. Car with current CVT produces some noise and slow acceleration to meet the car power demand. There are about jerky movement and non- uniform power transfers during i...
