Abstract
Brushless DC motors (BLDC) are preferred over brushed motors in industries because of many advantages such as increased reliability, reduced noise, higher speed range, better speed-torque characteristics, higher efficiency and high torque to weight ratio. This paper focuses on the remote monitoring of parameters of BLDC motor such as Temperature, Voltage, Current and Speed using Zigbee wireless technology and virtual instrumentation tool, LabVIEW. The results shown during the tests are accurate and the low-cost system is able to efficiently transmit the parameters remotely using ZigBee and display them on the LabVIEW front panel. The system can be of great importance in industries as it is not possible to manually access the motors functioning in hazardous environment. This system can also be used for predictive maintenance where the parameters monitored can be used to study the lifetime of the motor. The hardware requirements of the system are Arduino Microcontroller, two Zigbee (one as coordinator and other as end device), BLDC motor, an optical encoder for determining the speed of the motor, LM35 Temperature sensor for measuring the temperature, Current transducer, ACS712, for measuring the input current and Voltage transformer for stepping down the voltage before giving the input to Arduino to measure the voltage.
