SCR and RF Technology, AC Motor


The main aim of this project is to control the speed of an induction motor by applying varying voltages to the motor by using thyristors so that its speed can be controlled. We use a new idea to get varying voltages i.e. RF (Radio Frequency) technology. Yes! It is right, in this project we controlling speed of induction motor with a simple RF remote. When first button of the remote is pressed then we get particular speed after this if next button is pressed we get varied speed of the motor. The project uses zero crossing point of the waveform which is detected by a comparator whose output is then fed to the microcontroller. The microcontroller provides required delayed triggering control to a thyristors device which is SCR. Finally the power is applied to the loaded Induction Motor. This project uses a microcontroller from Arduino which is interfaced to thyristor control unit for increasing or decreasing the AC power delivering to the motor. The varying power shall result in variation in the speed of the motor. The project can be further enhanced by using such a separate units to control three phase induction motor.
