Abstract
This paper presents the temperature measurement and monitoring system for industrial induction motor (Squirrel Cage Rotor Motor). The aim of temperature monitoring system is to analyze and alarm an abnormality of the motor and prevent the damage in case of unbalance voltage. This system was tested by an induction motor of pointing machine. The experiment setup consists of a temperature measurement circuit using IC LM 35DZ with analog transformer used as a temperature sensor and transducer and the personal computer with data acquisition card from National Instrument PCI 6014 using Lab View version 7.1 for analyzing temperature data. The AC source was performed by adjusting voltage unbalance of 10%, 20% to 50% for each phase to monitor the temperature changes. This scheme can alert the operation of the motor in order to prevent damage and to extend the life time reducing maintenance costs.
