An electric motor could run a generator to power itself, but this is a lossy system, so an outside power source would have to supply the power due to the losses. And if the motor was being used for anything else, the real power losted due to this other use would have to be made up as well. You don't get anything for free.
No. This is perpetual motion, which is impossible, the problem is that everything has losses, like friction, drag, etc., and no matter how clever you get, the best you can do is that you can ALMOST make it work. Don't waste time pursuing this beyond understanding why it does not work.

Can you use electric motor on generator insted of petrol motor?
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.
Is a power supply needed to run an electric motor?
Yes. To make something move, you have to add energy. An electric motor won't turn by itself.
What is the problem with using an electric motor to run a generator stepped up with transformers that is used to run the motor and give electricity for other uses?
It's all to do with the conservation of energy. The output power of the transformer cannot be greater than the input power from the motor used to drive your generator! In fact, it will be significantly lower than the power of your first motor due to the efficiency of the motor, of the generator being driven by that motor, and of the transformer. So if you then try to run the original motor from the output of your transformer, the energy-losses will simply accumulate, and the motor will not be able to run!
What is the application of generator and motors?
A generator converts mechanical power into electrical power. A motor converts electrical power into mechanical power.
What is a DC generator the same as?
A DC generator, or "dynamo", is very similar to a DC electric motor but cannot be described as "exactly the same as a motor" because a DC generator's designed purpose is not to "use" electricity (which a DC motor does) but to "make", or "produce", electricity.
Can an electric motor run a generator to power itself if the motor has a small gear and the generator has a big gear?
Yes, it is possible for the electric motor to run a generator to power itself through a gear system, with the motor having a small gear and the generator having a large gear. This setup can create a mechanical advantage that allows the motor to turn the generator efficiently to produce electricity, which can then be used to power the motor.
What is the difference between an electic motor and an electic generator?
AC motor produce mechanical power and absorbed electric energy the power generator produce electrical power absorbed mechanical power
Will a 2800 watt generator run a 550 watt electric cement mixer motor?
Yes, a 2800 watt generator should be able to run a 550 watt electric cement mixer motor. The generator's wattage is more than enough to power the motor with some extra capacity for other devices. Be sure to check the starting wattage of the motor as well to ensure the generator can handle the initial surge of power needed.

What size generator do you need to move a 30 hp electric motor?
A 5 kW generator would turn it over but if the full 30 hp of mechanical power is needed, that would require about 30 kW of electric power from the generator.
What is the purpose of a in an electric motor?
A commutator applies power to the best location on the rotor, and in a generator, picks off power similarly.
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.
What is the main difference between an electric motor and electric generator?
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.
Can you take a 12000 watt gas powered generator and replace the gas engine with a electric motor to run the generator?
A 15 KW generator won't likely run everything in your house, but besides that it is not efficient. You will be using more electricity to run the generator than the power would deliver. You also defeat the reason for the generator - run your house when power goes out. Now if you had a wind turbine turning a generator you have a positive contribution to house power. This is how wind power works. There are also lots of issues associated with a power transfer switch and feeding power back into the grid.
What is the purpose of a commutator in a electric motor?
A commutator applies power to the best location on the rotor, and in a generator, picks off power similarly.
What are internal combustion power plant?
The power plant includes an internal combustion engine and a direct current electric motor generator.
Is a power supply needed to run an electric motor?
Yes. To make something move, you have to add energy. An electric motor won't turn by itself.
