Development of Single Phase Induction Motor Adjustable Speed Control using PIC-16F877 Microcontroller

R. Saravanan, F.X. Edwin Deepak

Abstract


This paper involves design & fabrication of the speed control of induction motor using PIC 16F877 Microcontroller. The microcontroller senses the speed feedback signal & consequently provides the pulse width variation signal. This pulse width variation signal is given to the inverter, which in turn provides the required frequency for the desired speed. PWM technique has been employed in this inverter to supply the motor with variable frequency. Pulse Width Modulation (PWM) is a common technique for speed control which can overcome the problem of the poor starting performance of a motor. It combines the technique of PWM generation and the control of speed of motor by variable frequency method using microcontroller
