Abstract
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 Android phone remotely through Bluetooth Technology. We are
using android application which uses Bluetooth to connect to the Bluetooth modem of the
control circuit. Bluetooth modem is interfaced with the AVR Microcontroller. The
Bluetooth slave receives the commands from the Android phone, then The Bluetooth
module sends the signal to the Microcontroller. 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 detect the temperature and voltage of it which can be
displayed on the android phone. Therefore, this project will be helpful in households,
commercial use, industries etc.
