    Speed Control Of A Dc Motor Through Plc Interfacing With Proximity Sensor
    (Department of Electrical and Electronic Engineering, 2021-12) HOSSAN, MD. AKRAM
    At present in the industry, the DC motor is commonly used because of its simplicity in speed control and it gives specific output, that’s why the necessity of the DC motor is in huge demand for industrial purposes. The object of this project is to develop a system where speed of DC The motor can be controlled by collecting the feedback of proximity sensor interfacing with PLC. DC motor speed can be controlled by many ways and also it is conducted for many purposes. The Key benefit of conducting DC motors at present because of the capability of controlling motor speed easily. All kind of DC motor has its inner process such as electro mechanical or electronic for changing the flow of current direction. But huge dc motors have several usage as like as propulsion of electric vehicles, elevators, etc. Basically we can control motor speed by using flux control technique, armature (coil) control technique, voltage control technique. Control of DC motor speed is vital where a huge change of speed is needed. In this project, developed an idea which is implemented for controlling DC motor speed using Proximity sensor feedback and Programmable Logic Controller (PLC) to fulfil the technique for controlling and evaluating the DC motor speed rotation. In an open loop system output is not dependable and also not properly accurate. Therefore to get more accurate output from system closed loop systems are used. Because in the closed loop system it can automatically controls to get a wanted position or set point without human collaboration. PLC is designed for industrial usage. It holds several sorts of i/o which are properly alike with the industrial instrumentation. PLC delivers the elasticity for programming particularly the "ladder language" which is related to industrial standard "ladder Network”.
