Abstract—This paper presents a new design of an electro-mechanical Continuously Variable Transmission (CVT) by using dual acting pulley at driver and driver sides with single actuator to vary the belt radius. Several conceptual designs on pulley geometry and its working mechanism were proposed and evaluated. The best evaluation design was selected and a prototype of the CVT system, namely single actuator double acting electro-mechanical (SADAEM) CVT system was built. All the mathematical equations will be derived in this paper and the modelling was developed using MATLAB Simulink software. The performance of the SADAEM CVT system was evaluated in term of belt radius and CVT ratio tracking by using proportional−integral−derivative (PID) controller. The results obtained by the simulation showed that the response trends were similar with an acceptable error.
