Abstract

Most of the industries use a high or low AC induction motor in their production line. These motors are used as industrial drives and they execute important processes in the industries such as manufacturing. Thus, a proper maintenance or services to these induction motors are vital to ensure all the process flow smoothly and not to be interrupted due to the induction motor broke down or not fully functioning. The objective of this project is to develop a prototype Smart Motor Mechanical Multimeter. This ³mechanical multimeter´ aims to provide facilitation and convenience to the maintenance technician where this device enables them to monitor vibration and temperature remotely, effortless yet reliable. The remotely monitored temperature and vibration can be viewed using Raspberry Pi. The Raspberry Pi is a micro-controller with touchpad that has GUI (Graphical User Interface) was implemented on this project to monitor vibration and temperature sensor of an induction motor. Two types of sensors were used. LM35 sensor and piezoelectric vibration sensor were implemented to measure temperature and vibration respectively. Both parameter monitoring can be viewed online and offline from the touchpad. To verify the data measured by the prototype, an industrial thermal gun, manufactured by Flir, is used. Both data were compared, and their comparison results showed that the error were relatively small. This shows that the temperature monitoring feature of the prototype is functional and more reliable compared to vibration sensor. Thus, future work for the prototype is to improvise the vibration monitoring. This prototype carries a commercial value because of its potential to assist temperature monitoring of a motor at an affordable cost, as compared to Distributed Control System (DCS). This will help Small Medium Enterprise (SME) local companies to grow supported b\ this protot\pe for motor¶s health condition remote monitoring i.e. temperature.
