ANDROID-CONTROLLED SPEED REGULATION OF INDUCTION MOTOR VIA CYCLOCONVERTER TECHNOLOGY

— This paper's primary goal is to create a model that uses an Android-based smartphone to regulate the speed of an induction motor, such as a fan. In this instance, an induction motor's speed can be remotely controlled using IOT. An Android phone serves as the transmitter, and the signal is received by a WIFI module receiver that is attached to a PIC controller. Every time, the written code is followed by the Android application (Blynk) to transfer data. The microcontroller then uses opto isolators to deliver the supply signal to the TRIAC. Consequently, the speed of the induction motor and the power to a load connected in series with a TRIAC are controlled by the signal that is received. In this design, feedback is also provided to the host. A speed counter is fastened to the induction motor's load in order to show the speed to the user. The induction motor is controlled via an android application called Blynk, which also shows the speed control options. In this project, we utilise a cycloconverter, or AC-to-AC conversion, in conjunction with thyristors to control an induction motor's speed in three phases. In question are three steps: F, F/2, and F/3. Vacuum cleaners and washing machines are two common household equipment that use single-phase induction motors. We can overcome the main disadvantage of induction motors, which is that utilising additional devices such as variable frequency drives (VFDs) to alter their speed is quite costly, by utilising a cycloconverter. The speed ranges (F, F/2, F/3, and F/4) of an induction motor speed control are chosen by means of the PIC18F458 microcontroller. Since it is difficult to accurately and affordably adjust the frequency of the AC supply, we used thyristors, or TRIACS, to make it operational. By connecting this in each phase, the three-phase induction motor can also make advantage of this.
