Single phase induction motors are widely used in home appliances and Industrial control because of their low cost and rugged construction. Many industrial processes require variable speed drives for various applications. Many applications need variable speed operation and one of them is a simple fan load. The RF generator which generates the analog output signal for the corresponding button pressed using PCB. This analogue output is fed to the RF Transmitter and sent through the antenna. At the other end, the RF Receiver picks up the signal and feeds it to the signal decoder, there the decoding takes place and this decoding data is given to the Micro controller RL78. The software in the Micro controller receives the signal and accordingly drives the TRIAC Circuit, which in turn is connected to load serially which is used to generate the PWM pulses for speed control of the single phase induction motor. The main aim of the this project is to design an real time electronic control system that can be used to control the speed of motors kept at remote locations using an embedded technology.
