REMOTELY OPERATED FOUR QUADRANT DC MOTOR CONTROL BY ANDROID APPLICATIONS
REMOTELY
OPERATED FOUR QUADRANT DC MOTOR CONTROL BY ANDROID APPLICATIONS
ABSTRACT:
The
project has been designed to develop a speed control system for dc motor in all
the four-quadrant. Using four-quadrant chopper it is possible to demonstrate
forward, instant forward brake, reverse, instant reverse brake control of a dc
motor using a microcontroller through remotely operated commands to it by touch
screen based user friendly gui on any smart phone with android applications.
This project uses regulated 5v, 750ma
power supply. 7805 three terminal voltage regulator is used for voltage
regulation. Bridge type full wave rectifier is used to rectify the ac output of
secondary of 230/18v step down transformer.
