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.

Generator is the device that generates electricity. Motor is a rotating device using electricity

An electric motor converts electrical energy into mechanical energy. While an electrical generator does the opposite.

No but you can use the motor to run a generator.

Yes, the generator needs an engine to turn the shaft at the right speed but it does not matter what type of engine it is. But power is lost in the conversion process so to use an electric motor with an electric generator is a circular and possibly questionable activity.

The sizing of the generator is dependant on the size of the electric motor driving the mixer.

the difference between a electric motor and a generator.Motor- is a device or equipment which convert electrical energy to mechanical energy.Generator- is a device or equipment which convert mechanical energy to electrical energy.

a motor is a generator and a generator is a motor, if you are applying a voltage to turn the rotor its a motor and if you are turning the rotor and taking the voltage off the terminals its a generator or alternator.

If the output power of the generator matches the required input power of the motor - sure.

I think it can work with a certain type of generator and an electric motor like one that uses 300w/h The idea is to run a generator that can produce more electricity than needed to run the motor that is powering it.

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.

An electric motor converts electric energy to mechanical energy while a generator converts mechanical energy to electric energy.

The British scientist William Sturgeon in 1832 invented the electric motor. The generator is just a motor running backwards. Michael Faraday, another British scientist, was also working on electric motors at the same time.

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.

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.

A diesel engine spins a generator, the generator powers the electric motor that turns the wheels.

An electric generator and an electric motor does the opposite!

when the motor runs more than rated speed it produces leading current and results act as a generator. (or) the motor act as generator when it produces more back e.m.f

Generator converts mechanical energy in to electrical energy, where as electric motor converts electrical energy in to mechanical energy.

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.

electric motor, generator and automobiles.

Motor is device which converts electrical energy to mechanical energy,where as generator converts mechanical energy to electrical energy

an electric motor converts the electrical energy into mechanical energy by rotation based on the principle of electromagnetic induction.and electric generator converts the mechanical energy into electrical energy based on the same principle but works reversed.
