I’m trying to build a small magnetic power generator and I need something that generates electricity when being rotated rapidly.
I heard of something called a DC motor and it can do it but i m not sure of the exact name of it. This DC motor does not need any electricity to start.
The type of motor that can most easily be used as a generator is a permanent magnet DC motor of the type that has a commutator and brushes. The required speed and torque and the voltage and current that can be generated are comparable to the motor’s speed, torque, voltage and current ratings for operating as a motor.
A brushless DC motor would probably work, but there are several types including some that have a built-in electronic commutator. You would need to learn what could be done with the different motor types.
Various other types of DC and AC motors can be used as generators, but some of them require external control circuitry and/or external power for starting and/or use as generators. Some types of motors can not be used as generators at all and some can be used as generators only after making internal modifications.
