The project is designed to drive an induction motor for the required application in forward and reverse directions using wireless technology. For example, an exhaust fan can be used in both the directions to get fresh air in and throw hot air out. This can be used in case of conventional exhaust a fan that rotates in one direction only.
This proposed system demonstrates a technology to rotate a squril cage induction motor in both clockwise and counter clockwise direction. It also has the provision to control the direction of the motor using a TV remote. When a TV remote button is pressed, it sends an IR signal in RC5 code which is received by an IR receiver called TSOP-1738. The microcontroller receives the infrared signal from the IR remote, the code of which is identified by the receiver to operate a set of relays. The relays switch ON/OFF the appropriate relay to power a split phase induction motor to achieve desired direction by interchanging leading supply phase from the main winding to the auxiliary winding. Output from the TSOP is fed to a microcontroller of 8051 family which is interfaced to a relay driver IC. Thereafter, the relay switching is done by-stable mode for a split-phase induction motor to rotate in forward and reverse directions.
This proposed system demonstrates a technology to rotate a squirrel cage induction motor in both clockwise and counter clockwise direction. This is a sensor based embedded project helpful for EEE students.
