Introduction of DC generator and checking the difference between generator and Alternator
What is an alternator and a generator?
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature. Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called an alternator, but usually, the term refers to small rotating machines driven by automotive and other internal combustion engines. Based on several audits, Wärtsilä delivered a comprehensive solution to bring EDG’s power plant up to standard again; including a complete overhaul of engines and alternators. In addition, automation was upgraded and auxiliaries were modified and fine-tuned to suit the plant performance. Finally, the turbochargers were also upgraded with newer versions.
what is a generator? What parts does it consist of? Which component in the dc generator produces a magnetic field? What are Generator and Alternator Difference? Alternator and generator, the two main parts in electrical appliances. You have definitely heard their names many times and even seen them. Would you like to know more about them? In this post, we will introduce the alternator and generator, check the Difference Between Alternator and Generator. We will introduce the DC generator and examine the Parts of dc generator. So read this article to the end.
DC generator working is the conversion of mechanical energy into electricity. 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.
DC Generator Parts
Here we first say the name of the part of dc generator, then we will explain each one.
End Housings
Stator
Commutator
Shaft
Stator:
A direct-current (DC) generator consists of two main parts, a rotating section and a fixed one. Stator is the stationary part of this system that includes a core, stator winding, and the outer frame and houses the rotor (the rotating part) in its core. Read more
Alternator vs Generator
In this section, we examine the differences between alternator and generator.
As we already mentioned, an alternator only provides AC, but a generator generates both AC and DC. So, if you need DC, your only choice between alternator vs generator would be a generator. With every half rotation of the rotor, the current’s direction changes, causing the alternating current. The circuit’s ends are directly connected to the load for getting the produced AC. And when it comes to direct current or DC, these ends of the wire should be connected to the commutator which converts AC to DC. To read more about Generator Alternator Difference, you can refer to the resources introduced at the end of the article
Advantage of Alternator vs Generator
Alternators have some benefits over generators which are as follows.
Higher output
Lower weight and smaller size
Less maintenance
