Abstract: Resulting from the slow fluid pressure responses and fluid viscosity loss, the present hydraulic-powered CVTs produce jerky movements, rattling noise and unequal power transmission at uphill climbing. The aim of this article is to present a design and prototyping of an electromagnetic actuated continuously variable transmission (EMA-CVT). Using the kinematics analysis of CVT clamping forces and electromagnetic forces, the EMA-CVT is modelled. An internet of things (IoT) has been developed to control the EMA-CVT gear ration with integrating a fuzzy logic controller CVT, wheel speed sensor, CVT pulley position sensor, and CVT secondary pulley revolution sensor. The fuzzy logic controller is used to control the current supply to the EMA. The CVT has a failsafe mode that allows to manually adjust the gear ratio if any of the sensor of the IoT system malfunctions. The EMA develops the electromagnetic force in the range of 185-266 N for the supply current in the range of 3-3.7 amps.
