PLC CONTROL OF THREE PHASE INDUCED MOTORS

Abstract

Remote control applications arevery popular in today's industries and even for a long time, engineers have been focused on improving industrial output. Inverter fed induction drive systems are one of the most prevalent applications that require remote control and monitoring. The speed of the motor, as well as the forward and backward turning directions of the motor are all controlled by various types of controllers in the drive system.A Programmable Logic Controller (PLC) can be used to implement this strategy also RS485module will be used in order to achieve the remote control system.Technically, a programmable logic controller is a process control device utilized mostly in the automation industry.“How does it affect in the progression of the work, electricity consumption and in the life time of the motor?” The aim of this thesis is creating a PLC with it is own softwaretogether with the VFD (Variable Frequency Drive) in order to completely automates the work of different motors at the same time by taking the information from different sensors and sending the adapted frequency to the motor, in order to have a quick and easy monitoring, less electricity consumption and increasing the life time of the motor.
