At present situation, all house and industries have more than one number of the ceiling fan which operates on an average of 10-15 hours/day. So the contribution of a fan in the overall energy consumption of house and industry is of considerable value since there is no existing system which deals with reducing the energy consumed by a fan. By our proposed system we can reduce the energy consumption of fan by controlling the supply given to it. To control the voltage a control switch is used in addition to a microcontroller. So by effectively reducing the energy consumption of the electric fan, major changes can be seen in overall energy saving in all houses and industries. In Single-phase induction motors for a high starting torque, a capacitor-start capacitor-run arrangement is used; the speed is usually controlled by voltage control methods. This paper is implemented to control the speed of split phase induction motor by controlling load voltage depends upon the ratio of ON and total (ON+OFF) periods or the number of ON and OFF cycles of the supply voltage.
