Can you use an electric motor as a generator?
Some types of dc electric motors can be used as generators of dc
current if they are driven by another source of rotating power,
such as a diesel or gas engine or an ac electric motor.
But many other types of electric motor - such as, for example 3-phase ac squirrel cage induction motors - cannot be used that way.
Can you take a 12000 watt gas powered generator and replace the gas engine with a electric motor to run the generator?
Can an electric motor run a generator to power itself if the motor has a small gear and the generator has a big gear?
of course you can.but the purpose of electricity is lost here.generators run by petrol or diesel engines are used because you dont have a electric supply or there is a power outage.if there is no power how can you run the electric motor which runs the generator.hence the generator is always coupled with and diesel IC engine.
What is the difference between energy conversion that takes place in an electric motor with the conversion that takes place in a generator?
When the motor is doing some work at the same time can it generate power with help of another generator is this possible like this anything there?
You can't use a motor to power a generator and use the output of that generator to power the motor. Some energy will be lost at each step making the hookup pointless. But you can use a combustion engine to power an electric generator and use that electricity to power auxillary systems around the engine.
An electric generator converts mechanical energy to electric energy while a motor converts electric energy to mechanical. A generator can actually act as a motor if it losses whatever is making it spin (called "motoring"), which is usually a very bad thing. Motors may be used as generators as well, depending on their design.
Both generator and motor are energy converters. Subject to losses, both convert one form of energy into another. All motors and generators use a form of motion on one side of their energy conversion process (typically, but not necessarily, rotary motion). For example, a petrol engine is a motor that converts combustible fuel into rotary motion, an electric generator converts (typically rotary) motion into electric energy. Complimentary motor/generator pairs are only possible among certain forms…
i believe that you can turn an ac electric motor into a generator only if you use one ore more capacitors to excite the motor and to store a charge ,unless you are using a dc motor which consist of a rotor and a stator which is no more than a coil spining in a permanent magnetic field,if you use a power regulator it,s much to complicated,so i think that if you use some capacitors…
How do you build an electric motor run a generator to power itself if the motor has a larger gear and the generator has a smaller gear?
You cannot build a motor generator set that would power itself. That would constitute a perpetual motion machine which, due to losses in various components, is impossible. Even though you spin the generator faster than the motor, the motor will be required to provide more torque, representing more power than the generator is capaple of producing.
Some types of motor can work equally well as a generator. A DC motor runs on a DC supply and supplies a mechanical load. If the load is removed the motor will free-run a little faster. But if the shaft is then driven faster than that, the current flows the opposite way and the motor has become a generator.
The propellors are attached to a shaft that turns a gearbox that turns an electric motor that produces electricity. You need to study how an electric motor generator works. A regular electric motor turns when electric current is run through it. There are coils of wire wound a rotating armature that is placed between Magnets. An electric generator is made very similar. When the wire coils are rotated within the magnetic field, this produces electricity.
