Design,Conditioning and Monitoring of 3 - Phase Induction Motor using PLC

Induction motors are commonly used in various industrial fields appropriate to their simple, strong and reliable process. Therefore, to get the suitable output and efficiency continuous controlling and monitoring is required Squirrel cage induction motors are commonly used motors in industry since, of its strong construction and small maintenance. Three phase induction motors are mainly used AC motors in industry for various operation. At this time the functioning of condition monitoring system for the 3-phase induction motor based on programmable logic controller technology. In this paper, various aspect of 3- phase induction motor such as speed; temperature, voltage and current are controlled and monitored using the PLC and the implementation of a for speed control, direction control, parameter monitoring on screen is provided. Induction motors are commonly used motors in industry as at times the condition like over voltage, under voltage, overloading, overheating, over speed etc. may give rises to unnecessary conditions for the motors. Thus, condition arises the motor have to turn off automatically. All the required control and motor performance monitoring data will be taken PLC for further analysis. Here the various factors are monitored using sensors and PLC and if any harmful condition arises motor is turned off automatically.
