Coil A coil symbol typically represents the coil of a relay that drives the contacts. This symbol can also represent a digital output from a PLC or an electrical load. Normally-open Contact This symbol typically represents the contacts of a relay, with power on both coming into the contact and power leaving contact. Electrical Symbols and Line Diagrams Chapter 3 Material taken from Chapter 3 of Electric Motor Controls, G. Rockis, 2001 One-Line Diagrams One-line diagram - a diagram that uses single lines and graphic symbols to indicate the path and components of an electrical circuit.

Misc. Symbols; Motor: Electric motor: Transformer: Change AC voltage from high to low or low to high. Electric bell: Rings when activated: Buzzer: Produce buzzing sound: Fuse: The fuse disconnects when current above threshold. Used to protect circuit from high currents. Fuse: Bus: Contains several wires. Usually for data / address. Bus: Bus. The control circuit is separate from the motor circuit. The control circuit may not be at the same voltage as the power circuit. When the voltage of the control and power circuits is the same, it is referred to as Common Control. If the volt-ages are different, it is called Separate Control. Figure 4. Typical Starter Wiring Diagram — Three-Phase Basic wiring for motor control - Technical data They show the relative location of the components. They can be used as a guide when wiring the controller. Figure 1 is a typical wiring diagram for a three-phase magnetic motor starter.

Figure 10.1. When the "Forward" pushbutton is actuated, M 1 will energize, closing the normally-open auxiliary contact in parallel with that switch. When the pushbutton is released, the closed M 1 auxiliary contact will maintain current to the coil of M 1, thus latching the "Forward" circuit in the "on" state. The same sort of thing. M , W, A , and 50, representing a motor, watthour meter, ammeter and overcurrent protective relay, respectively. Eaton Corporation Electrical Sector 1111 Superior Ave. Cleveland, OH 44114 United States 877-ETN-CARE (877-386-2273) Eaton.com These electrical symbols are commonly used in industrial electrical diagrams, ladder diagrams or prints. We have programs that allows you to draw, test and print electrical diagrams or how to understand and read electrical diagrams.We also carry PLC training and motor control training DVD series. Glossary. Also known as a "maintaining" contact, these are the normally open contacts of a magnetic starter that are connected in parallel with the start button in a three-wire control circuit. When using the conventional NEMA numbering system, they get wire numbers "2" and "3." A device used for measuring the value of current flowing through a.

These the basic symbols of motor control diagrams. Motor control relays can be energized from the same supply as the motor or from lower voltage sources that are interlocked with the main power supply. The interlock de-energizes all power to the motor and control for safety The symbols above are combined into diagrams called ladder diagrams. 3 Basic principle An electric motor is a device converting electrical energy into mechanical energy (generally a torque). This conversion is usually obtained through the generation of a magnetic field by means of a current flowing into one or more coils. Electrical energy Motor Mechanical energy

Electrical motor Generic symbol DC electric motor It can do the functions of motor or generator Single-phase induction motor with access to winding DC compound excitation motor Shunt winding Electric motor with terminals Linear motor AC single-phase series motor Shunt excitation motor DC shunt Serie winding Two-speed motor DC electric motor. Electric motors are electromechanical devices whose function is to transform electrical energy into mechanical energy through electromagnetic interactions. There are other engines ( generators) that produce electricity by exploiting the mechanical energy, such as alternators and dynamos. It may interest you.
