Brief Dc generator Separately excited dc generator In a separately excited dc generator, the excitation produced in the dc generator is by an external source. the separately excited field winding consists of several hundred turns of fine wire. The magnitude of voltage generated depends upon the speed of armature rotation and field current. Separately excited …

An induction generator is also known as an asynchronous generator. Like a DC machine, the induction machine works both as a motor and generator. What is an induction generator? An induction generator is an induction machine that works as a generator when the slip becomes negative. And then it starts supplying energy back to the …
The effect of flux produced by the armature current on the flux produced by the main pole is known as armature reaction. Let us consider a two poles dc generator which is shown above. When no load is connected to the generator, then the current of the armature conductor becomes zero. Only the MMF of …
We discussed the basics of dc generators in one of our previous articles. This article emphasizes the dc generator working. Before understanding the dc generator working in detail. Let’s know the basic principle first. DC generator works on the principle of faraday’s law of electromagnetic induction. Which states that whenever a conductor is placed in …
DC generator can be used as a DC motor without any constructional change and vice-a-versa. So, both can be termed as DC machines. In dc machine field magnetic flux can be produced by current-carrying field coils. And the process of production of magnetic flux in the machine is called excitation. Excitation is of two types …
Generators are devices that convert mechanical energy into electrical energy. The generators are normally used as a backup supply when power from the grid is unavailable. Generators are classified based on the output they provide into two categories: AC generator and DC generator. In this article, we try to understand about DC generator. How does …
