In electricity generation , a generator [1] 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 by British scientist Michael Faraday.

The rotating machines function on the same principle of electromagnetic induction those are the motor and the generator. Even though the principle is the same their the output they deliver differs due to the operational difference. This difference in operation is important for the machines to be classified as either a motor or a generator. Similarly, the individual machines can also be classified as ac or dc typed depending on the input and output they deliver. So, let us discuss in detail about this topic.

As we know that electrical generator is one kind of machine, used to change the energy from mechanical to electrical using the electromagnetic induction principle. So this will cause a flow of current within the conductors. Here, the flow of the current direction can be found with the help of the right-hand rule of Flemming. Based on the attained output, this electrical generator can be classified into two types namely AC generator and DC generator. This article discusses the main difference between AC and DC generators. These differences are listed in a tabular format where these differences can aid engineering students to learn about this concept in a better way.

Difference between AC and DC Generator

The major difference between the alternator and the generator is that in alternator the armature is stationary and the field system rotates whereas in the generator armature rotates and field is stationary. The armature of the alternator is mounted on the stationary element called stator and field winding on a rotating element. While the connection of a generator is just the reverse of it. The other differences between them are shown below in the comparison chart. The alternator and generator both works on the principle of Faraday law of electromagnetic induction.

The AC current changes its polarity and magnitude periodically and continuously with respect to time. The Ac current can be produced with a device named alternator that produces the alternating current. Suppose a piston is inserted inside a pipe and connected with a rotating rod as in the pin pic below. Here the piston has two strokes one towards upward and the other towards backward on the upward stroke, the water moves in a clockwise direction and the backward direction the water displaces in an anticlockwise direction so in this way water direction changes its direction periodically with oscillation of the piston. Every Ac Waveforms have a divider line or called the zero voltage line that divides the waveform two halves as the Ac current changes the magnitude and direction periodically so on every one complete cycle it reaches zero volts.


AC and DC generators both use electromagnetic induction to generate electricity. However, the process they use is different. An AC generator creates an.

General Information: Emergency Contact: Email: contactus powerplus. Is your business in need of an AC generator or a DC backup generator? Can you tell the difference between the types of generators available on the market and which one best fits your needs? Here is what you need to know so you can invest in the right generator for your business.

The Electric Motor and Generator are differentiated on various factors like the main principle of working or function of the motor and generator. Consumption or production of electricity, its driven element, the existence of the current in the winding. The Difference Between the Motor and the Generator are explained below in the tabulated form. The motor and the generator are almost similar from the construction point of view, as both have stator and rotor. The main difference between the two is that the Motor is an electric device which converts electrical energy into mechanical energy.

Electrical Academia. The AC generator generates an output voltage which alters in amplitude as well as time whereas the DC generator generates a constant output voltage which does not change in amplitude as well as time.

 Без воска.  - Он улыбнулся в ответ. Она поцеловала. - Скажи, что это. - Ни за что на свете.  - Он засмеялся.

Черные линии, сбившись в кучу вокруг ядра, настолько сгустились, что их масса стала совсем непрозрачной и легонько подрагивала. Мидж отвернулась. Фонтейн стоял очень прямо, глядя прямо перед. У Бринкерхоффа был такой вид, словно он вот-вот лишится чувств. - Десять секунд.

 Не кажется ли тебе, что это звучит как запоздалое эхо. Она тоже засмеялась. - Выслушай меня, Мидж. Направь мне официальный запрос. В понедельник я проверю твою машину.

Она зажмурилась. - Попробую угадать. Безвкусное золотое кольцо с надписью по-латыни. - Нет.  - Он усмехнулся.

 - Я знаю эту гостиницу. Она совсем .

Кто-то звал. Он попытался оторвать голову от пола. Мир кругом казался расплывчатым, каким-то водянистым. И снова этот голос.

 Сэр, - задыхаясь проговорил Чатрукьян.  - ТРАНСТЕКСТ вышел из строя. - Коммандер, - вмешалась Сьюзан, - я хотела бы поговорить… Стратмор жестом заставил ее замолчать. Глаза его неотрывно смотрели на Чатрукьяна. - В него попал зараженный файл, сэр.

Только тронь ее, и он тебя прикончит. ГЛАВА 56 Мидж Милкен в сердцах выскочила из своего кабинета и уединилась в комнате для заседаний, которая располагалась точно напротив. Кроме тридцати футов ого стола красного дерева с буквами АНБ в центре столешницы, выложенной из черных пластинок вишневого и орехового дерева, комнату украшали три акварели Мариона Пайка, ваза с листьями папоротника, мраморная барная стойка и, разумеется, бачок для охлаждения воды фирмы Спарклетс.

In a DC generator, the electrical current flows only in one direction. In an AC generator, the coil through which the current flows is fixed while the magnet moves. The construction is simple and costs are less. In a DC generator, the coil through which the current flows rotate in a fixed field.

uniform magnetic field in a convenient fashion induces a voltage between the loop terminals. This effect can be used to build an electric power generator, such as.
