1. AUTOMATIC SPEED AND TORQUE MONITORING IN
INDUCTION MOTORS USING ZIGBEE AND SMS
ABSTRACT:
This project is for monitoring the speed and torque in induction motors in real time by
employing ZigBee based wireless sensor network. An embedded system is used for acquiring
electrical signals from the motors in a noninvasive manner. The processing for speed and
torque estimation is done locally. Embedded system is used to control the speed of the motor.
The values calculated by the embedded system are transmitted to a monitoring unit through
ZigBee based wireless sensor network. The real time monitoring of various motors can be
done at the base unit. Speed of deployment, maintenance, low cost, security, reliability and
throughput are the main advantages of using ZigBee. From simulation, plot for output
voltage, output current, speed and torque can be obtained by applying different load values.
