    Induction motors are widely used in many industries and domestic applications. They are used commonly in many open-loop control applications due to their cost, size, efficiency, less maintenance, simplicity and easy manufacture. In the past traditional speed control methods were used to control the speed of the DC motors, But DC motors have commutator and brushes which require more maintenance and hazardous. So Induction motors are more preferred in these fields. Since most of the industries use Induction motors, controlling of it plays a major role. This project deals with controlling the speed of Induction Motor using cycloconverter with IOT. The It decodes the signal and generates the pulse width signals which activates its circuit and gives the change in speed of induction motor with respect to the change in firing angle of TRAIC. This way speed can be easily varied and maintained as per the required values. We are not only controlling the speed of the induction motor, we can also provide time to time updation of running motor through the IOT. Which can be displayed through mobile app.. Therefore, this project will be helpful in households, commercial use, industries etc. A cycloconverter is a power electronic device used to convert constant voltage constant Frequency AC power to adjustable voltage adjustable frequency AC power without a DC link. In among all the methods this method is simple, reliable and economical. The various speed of induction motor is obtained by varying the supply frequency by using cycloconverter.
