We have employed an Embedded Microcontroller for controlling the speed of the AC Motor. This project uses the SCR to change the firing angle, so that we can vary the speed of the AC Motor. Even it has field and armature control. It also has an internal Acceleration and De-acceleration control. Because when we operate we can vary the speed instantly by changing the potentiometer, but the response will be controlled based on the Acceleration and De-acceleration timings for safety reasons.
