Hello,
All electrical motors can be run in generetor, but depending on the motor
it will be more or less difficult.
An induction motor will work as a generator if you make it turn faster
than the sync speed. So a three phase induction motor with a sync speed
of 1800 rpm, if you run it at 1801 an more rpms, you will be generating.
But that may be too complicated for you because you need to have an
"exitation source".
The easiest method may be to use a PMSM (Permanent Magnet Synchronous
Motor) or a PM DC motor. This way, if you turn the shaft, you will
generate electricity right away. If you use a PMSM, with a diode bridge
rectifier you will have a DC link with some fluctuation. With the PM DC
Motor, with a constant speed you will have a Constant DC link. The more
amps you will pull, the more torque the motor/generator will create.
Anyway, good luck with your project.
