A simple AC generator consists of:Figure 3 Simple AC Generator(a) a strong magnetic field, (b)conductors that rotate through thatmagnetic field, and (c) a means bywhich a continuous connection isprovided to the conductors as theyare rotating . The strongmagnetic field is produced by acurrent flow through the field coilof the rotor. The field coil in therotor receives excitation throughthe use of slip rings and brushes.Two brushes are spring-held incontact with the slip rings toprovide the continuous connectionbetween the field coil and theexternal excitation circuit. The armature is contained within the windings of the stator and isconnected to the output. Each time the rotor makes one complete revolution, one complete cycleof AC is developed. A generator has many turns of wire wound into the slots of the rotor.
The magnitude of AC voltage generated by an AC generator is dependent on the field strengthand speed of the rotor. Most generators are operated at a constant speed; therefore, the generatedvoltage depends on field excitation, or strength.

What is the difference between electricmotor and generator?
An electric motor is an AC motor which works with alternating current But Generator is D. C motor that works under the principle of direct current
How generator operates?
It works with two reactor coils for excitation of the field reactor coil , which in turn provides current to the field. The two reactor coils are connected in shunt and series with the output of the generator stator or armature ( from where load is connected).
What is excitation in generator and 2 methods each?
when the current is passing through the winding then it is called "Excitation". Types of excitation (1)seperately excited generator. (2)self excited generator. self generator is classified into 3 types. 1.shunt generator. 2.series generator. 3.compound generator. compoud generator is again classified into 2 types. 1.short shunt generator. 2.long shunt generator.
What are different methods of excitation of dc generator?
when the current is passing through the winding then it is called "Excitation". Types of excitation (1)seperately excited generator. (2)self excited generator. self generator is classified into 3 types. 1.shunt generator. 2.series generator. 3.compound generator. compoud generator is again classified into 2 types. 1.short shunt generator. 2.long shunt generator.
What is the basic principle of Generator excitation?
The basic principle of generator excitation is that once the gasket of tie generator is being checked, the generator excits as if the block is not inserted. By egbebu emmanuel
How does a carbon generator work?
it works.
An electrical generator works by moving a coil of wire relative to?
An electrical generator works by moving a coil of wire relative to a magnetic field.
Is there a generator that works without surveys?
heck no
Is there a swagbucks generator that works on Mac?
Nope.
How variable speed generator works and its specification?
First you have to understand how a generator works. Basically the excitation voltage is what varies according to generator output. Usually on a power source that has a inconsistant rpm, the excitation voltage will vary similar to a govenor in order to hold the generator output constant.
How do you tell generator on 1983 Honda gl 1100 works or not?
Start the generator and check the voltage output at the receptacles on the generator with an AC volt meter.
What is the difference between electricmotor and generator?
An electric motor is an AC motor which works with alternating current But Generator is D. C motor that works under the principle of direct current
Does the MineCraft gift-code generator MineCat work?
No it doesn't. I have it, and it no longer works.
How does an electric generator works?
The voltage was produce by cutting of the magnetic flux by the conductors.
Does anybody know where I can buy a solar generator?
You can buy a solar generator at Goal Zero or at their website. You can also build a solar power generator for under 300 dollars. The instructions are on the How Stuff Works website.
What is a signal generator for a speedometer?
if the speedometer works off of an input wave (sinusoidal signal) you would think the signal generator would be a source of reference
Which device works by rotating a coil within a magnetic field to produce an electric current?
generator
