Introduction of DC generator components

 DC generator is one of the most important parts in industry and electricity. In this article, we will first introduce the DC generator and then name and review the different parts of the DC generator.

In electricity generation, a generator is a device that converts motive power (mechanical energy) into electrical power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines, and even hand cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids. Read more



The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity; frequently they make acceptable manual generators.



DC Generator Parts:

DC generators are generally made of 
  • the magnetic field systems
  • shafts
  • yoke
  • brushes
  • armature winding
  • end housings
  • pole shoes
  • commutators
  • bearings

In the following, we will examine each of these sections separately:

Yoke

If we divide the DC generator parts in two, Yoke is the outer cover that not only provides mechanical protection to the whole inner assembly and fixes them to the foundation of the machine, but also creates a path for the magnetic flow that the field winding produces.
Based on the size of the machines, yokes are of two kinds and materials; in large apparatuses, yokes are made up of cast or rolled steel while in smaller ones they are composed of cast iron.

Everythings about Gas Turbine

Image
In this article, we are going to introduce a gas turbine. We will also examine the Gas Turbine Cycles and its different types. What is Gas Turbine: A gas turbine, also called a combustion turbine, is a type of continuous and internal combustion engine. The main elements common to all gas turbine engines are: an upstream rotating gas compressor a combustor a downstream turbine on the same shaft as the compressor. The first gas turbine type was turbojet engines. Although they look entirely different from reciprocal engines, they operate on the same principle: intake, compression, power and exhaust. In this type of engine, air is moved at a high speed to the fuel inlet and ignitor of the combustion chamber. The turbine induces accelerated exhaust gases by expanding air. Click here to read more about different types of gas turbine . Which cycle is used for gas turbine ? The basic operation of this turbine type has roots in the gas turbine cycle which is also known as the Brayton cycle. ...

How To Increase Cooling Tower Efficiency?

  cooling towers. A device for dissipating heat from processes such as water evaporation. In this article, we will introduce solutions for Increasing Cooling Tower Efficiency . Stay with us. The U.S. Department of Energy (DOE) is proposing to provide funding to the State of Arizona to replace parts of the heating, ventilation, and air condition system that have reached their expected useful life with more energy-efficient equipment at the Arizona State Veterans’ Home in Phoenix, AZ. Specifically, the cooling towers, condenser pumps, air dirt separator, interconnecting piping with valves and fittings, and the controls would be replaced. a cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed circuit dry cooling towers, rely sol...

Introduction of electric motors and types

Image
  You've probably heard of electric motors by now. A critical piece in all electrical appliances. In this article, we will introduce electric motors in detail and examine its types, so stay tuned. An electric motor is a component that converts electrical energy into kinetic energy. Most electric motors are  electromagnetic -based. Most electric motors are rotary, but there are also linear motors. In a rotating motor, the moving part (usually inside the engine) is called the impeller or rotor, and the fixed position is called the station or stator. The motor consists of electric magnets wound on a frame. Although this frame is often referred to as armature, the term is often misused. Types of Electric Motor Electric motors may be classified by considerations such as power source type, internal construction, application and type of motion output. In addition to AC versus DC types, motors may be brushed or brushless, may be of various phase (see single-phase, two-phase, or three-...
