How do electric generators work?
415304
Electricity and magnetism are closely related.  When a current goes through a wire, it creates a magnetic field around the wire.  Similarly, if a magnetic field is moved past a wire, it can induce a current.\n\nA generator spins a magnet past a series of coiled wires, inducing currents in them.  Generators and alternators both work in this way.  The difference between the two is that in a generator, the current always goes in the same direction, while in an alternator, it switches directions due to the fact that the polarity of the magnet changes as it rotates.\n\nGenerators always produce Direct Current (DC current), while alternators always produce Alternating Current (AC current).\n\nThe difference in nuclear, steam, coal, oil and hydroelectric powerplants is simply in how the rotation of the generator is produced.  The generators work in exactly the same way in each case.\n\nSolar power is different.  In the case of solar power, the current can be generated in one of several different ways.  These are more complicated, however, and I don't know the specifics of how they work.  Sorry.

A generator produces a current by moving a wire through a magnetic field.  If you had an infinitely large magnetic field, you could move in one direction forever and produce a dc current.  However, it isn't practical to do that.\n\nInstead, you put a ball of wire inside a much smaller magnetic field and you spin it.  The ends of the wire have to be touching something to complete the circuit so electrons can flow.  At one part of the circle, the wire is moving left to right across the magnetic field and causes electrons to flow in one direction in the wire, in another part of the circle, the wire is moving from right to left and the electrons flow in the opposite direction.  This is what causes the current to alternate.\n\nSo, when converting motive energy into electricity, ac current is the easiest to produce.  This is like what is produced by a car's alternator or a hydro-electric plant.

Generator generates electricity. It has a wire armeture mounted in an electic field. When the wire armeture is rotated, electric current is induced in the armeture du to change in magnetic flux.

hey men first know wat is a turbine.\nA turbine is a prime-mover used to provide the mechanical energy required for the generator.\nPrinciple of generators:\nwhenever a flux linking in a conductor changes there is an emf induced in the conductor.\n\nhere the flux is provided initially by a battery or some electrical source and the mechanical energy is provided by the turbine.\n\nIf u see the Mechnical energy from the turbine is converted into electrical.\nRemember energy can be converted from one form to another.This is the basic law.

Electricity is a form of energy.\n\nIt can be generated from other forms of energy, for example, chemical energy (burning fuel, or a battery), mechanical energy (a windmill), nuclear energy (atomic fission reaction like in a power plant).\n\nIn a battery electrical energy is converted from the  potential energy stored in chemicals which is released when they combine.\n\nIn a fuel cell, chemical energy is released in another type of chemical reaction.\n\nNuclear plants, windmills, hydroelectric dams or burning fuel in a generator turns a turbine or motor which moves a coil of wire through a magnetic field which produces energy.\n\nIn thermoelectric energy, heat is turned into electricity when two different metals are heated.

generator.\n\nAn AC generator is turned by mechanical power like steam engine or a jet turbine. When its coils spin in a magnetic field, electricity is generated\n\n\nz

Moving water -- generally provided by a river -- is used to turn a turbine.  The turbine is wrapped in conductive cable, and the housing is lined with magnets.  Thanks to the Oersted Effect (or maybe the Faraday Effect; I get them mixed up), moving a conductor through a magnetic field generates an electric current.  The stronger the magnets and the more conductor involved, the more current you get -- which is why hydroelectric turbines are so freakin' big.

There is a lot of possibilities starting from the simplest one which is wind generator.  More complicated would be water generation where a usually dam is build and potential energy of the water accumulated behind the dam moves water through turbines and generates power. Some other may include thermal energy of the earth. If you drill deep enough you will get to the earth crust zone where temperature is high to produce steam and this steam is converted (generated) into the electric power. Ocean waves are also source to generate energy.

Not sure I understand exactly what you are asking so I'll ramble a bit.\nIf you are asking about a gas turbine generator used to produce electrical power:\n\nThe gas turbine itself has 3sections. The compressor, combustion section, and the turbine. \n1) Compressor - multiple stages. Purpose is to increase the intake air far above atmospheric for more efficient combustion in the combustion section.\n2) Combustion section - this is where the fuel(can be fuel oil or natural gas) is mixed with the compressed air and ignited. This hot gas directed into the turbine section.\n3) Turbine section - hot gasses from the combustion section enter the turbine section where the high speed hot gasses cause the turbine to rotate(very oversimplified) thus converting the energy from the combustion process into mechanical energy...ie causing the turbine to rotate.\nUsually the turbine and compressor are on the same shaft...ie the turbine power is used to drive its own compressor.\n\nNow if this is a turbine generator: The shaft of the gas turbine would be mechanically coupled to an electrical generator which would produce the power.

Large commercial generators do not have permanent magnets. The rotating field is magnetized via slip rings that feed current into it's windings. The current is generated by the exciter which is either a small generator attached to the end of the shaft or, in modern applications, an electronic SCR converter.

Since you're dealing with a variable energy source (wind), you're best bet is to build a DC generator...\n\nIs this a science progect?\n\nA DC Generator is the same machine as a DC motor...  So if you're building something for your home, then just use a DC motor and a simple belt an pulley to reduce the rotational resistance (or load) on the blades, so a slower wind can be used...\n\nFor a Science project...  \nBuid three loops of wire and seperate them 60° on the rotor of the wind mill.  Place a magnet on either side. north to south\nSet up "brushes" (chunks of graphite like pencil lead) on either side so that as the rotor spins with the wind, the same side is going to the same terminal + or - no matter which side of the coil it is.\n\nHave fun with it...

It uses a permanent magnet which is rotated by a crank. The spinning magnet is positioned so that its north and south poles passed by a piece of iron wrapped with wire. It was discovered that the spinning magnet produced a pulse of current in the wire each time a pole passed the coil. Furthermore, the north and south poles of the magnet induce currents in opposite directions. By adding a commutator, it is possible to convert the alternating current to direct current.

I don't know the exact definition, but they differ on the way they deliver energy.\nDC generators give electricity at a given steady voltage, but AC generators give electricity in an continuous alternating voltage.

It depends on the type of motor. A dc motor may be used as a generator provided it is either a permanent magnet type or has sufficient residual magnetism in the iron to start off the generation.

thats basically the idea of a hybrid engine, except instead of powering a house, it helps power the car. see, electric motors actually work as electric generators in reverse, so hybrid cars have a gas and electric motor. the electric motor generates power when braking, which is stored in batteries. then, when you start up again, the electric motor helps accelerate so the gas engine doesnt work so hard. its alot easier and more efficient to use the stored enrgy within the car rather than putting it into the power grid.

DC series wound motors and generators are the same thing. One you apply mechanical power to and you will get a rippled DC wave form out. The more commutator bars (or magnets) there are the less ripple you get.\nAlternators (generators) are like you find on a car and in the generator sets that power the world. They have rings that go all the way ring the armature instead of the slits in commutators. This means that as the armature spins through the fields of the magnetic an alternating current is induced through the winding and out through the two rings. This is better for the transmission of power over distances rather than DC. So two rings are single phase, three rings are three phase. \nThe difference in a car is that after the AC is produced a set of diodes rectify the current and then a regulator levels it to 13.8volts DC cause batteries dont like AC.

The only motionless electromagnetic generator I know of is a solar panel.  While you can generate energy with coils you need a strong changing magnetic field.   The only way I know how to make one  without a preexisting current is spinning some kind of a magnet by wind, water or steam.\n\nNo something does not have to work to get a patent.  It is not the patent offices job to make sure something works.\nA patent is only good if you can successfully sue someone for infringing on it.\nI can patent an teleportation device right now if I want too but unless builds one almost exactly like the one I describe I am just wasting my time and money.
