make electricity from electric motor?

Question

make electricity from electric motor

Answer 1

Actuall the basic difference between a motor and generator is power flow. A motor consumes electrical power to produce mechanical energy while a generator is the opposite, consuming mechanical power to produce electrical power.


Some motors are very easy to use as a generator while others would require some minor modification and power source.

Since electrical generation is basically spinning a magnetic field inside a coil of wire a simple DC motor with permanent magnets is easily converted into a generagor just by spinning the shaft.

Other electric motors do not have permanent magnets but use electro magnetic fields. So you would have to power an electro magnet and spin the shaft in order to generate electric power.

Commercial generators use electro magnets as well but there design is such that upon start up residual magnetisim in the armature is enough to generate a small voltage which builds up. As the voltage output builds up a portion of it is regulated to the electro magnet so as to provide a consistent output voltage.

Answer 2

To make electricity you need a dynamo, but this is very basically just an electric motor that you physically turn somehow, and the movement of the windings relative to the magnets generates a flow of electrons in those windings.

Answer 3

you need a generator not a motor . and it you want to rotate the turbine by using motor again yuo requre electricity so thats of no use
