A contactor is an electromechanical device used to switch an electrical circuit on or off. It's commonly used in control circuits for motors, lighting, heating, and other electrical loads. Contactors use an electromagnetic coil to control the opening and closing of electrical contacts to manage the flow of electricity in a circuit. A contactor typically consists of several key components: 1. Coil: The coil is an electromagnet that, when energized, generates a magnetic field to pull in the contacts, closing the circuit. Contact of coil in the contactor named A1 and A2 2. Contacts : These are the points where the electrical circuit is either connected or disconnected. Contacts can be made of various materials, like silver, and are designed to handle specific voltage and current ratings. Normlly close (NC) and Normally Open (NO) 3. Enclosure: This is the housing that protects the internal components of the contactor, shielding them from environmental factors and ensuring safety. 4.

There are many circuits in electromagnetic control system, but actually all of circuits have same characteristic each other. here i will explain you from basic till advance skill. as newcomer for control we have to study from basic. in basic skill, there are several control system that you have to master before next step. here the basic skill: 1. Open control system  2. Close control system  3. Self maintenanced control system 4. Any location control system  5. Interlocking control system 6. in series control system. in this, i will explain you Open Control System:  open control system is one of the simpliest control system. in its control, using N ormally Open (NO) contactor. you can follow the step below (in making circuit open control system) using software EKTS (Electrical Control Techniques Simulator). VIDEO TUTORIAL  Open the software , EKTS   front of view EKTS: After opening the software you wiil see the view of EKTS like below. And then p

Contactor is an electromagnetic switch used to control any devise in industrila like electrical motors, lighting, heater, or other heavy load.  figure 1(contactors in spiral mixer) in operating system of contactor, it is devided in two parts:  --- power contactor (PC):  PC is the contact used power circuit, switch on or off electrical motor/lighting/heater/etc. Usually, a power contactor has 3 main contacts which shown figure 2 below.  --- auxiliary contactor (AC): AC is used    the contact used in control circuit, switch on off control system. Usually, auxiliary contact is consist of Normally Open (NO) and Normally Close (NC).   figure 2  (https://www.etman.no/) Part of contactor has special tagging according to IEC:  A1, A2    : is contacts of coil contactor 1, 3, 5      : is supply contacts in power circuit 2, 4, 5      : is load contacts in power circuit 13 & 14   : nomally open contacts (NO) 23 & 24   : nomally open contacts (NO)

What is an electromagnetic control system? electromagnetic control system is a device used to control or regulate the activities undertake in an industy. there is also a saying taht the electromagnetic control system is the equipment used to regulate the working system of electric motor be it an A.C. or D.C. motor. How importance is the electromagnetic control system in the industry? In this modern era the existence of industry is increasing rapidly from the simpliest to the most complex. Almost all industries in the world use a control system. the existance of an electromagnetic control system in an industry becomes very importan, because with the existence of electromagnetic control system all be easy, lightweight, fast, efficient, and practical. without an electromagnetic control system activities in the industry will not run. What equipment needs to be controlled in the industr y?  As already explained earlier that electromagnetic control system are used to regulate the
