Briefly tell who you are. :ph34r:

I'm a senior student studying EE at UC Berkeley, specifically analog circuit design. B)
Maybe you can help me with this:
I have the motor NC5475B motor rated from 3.5 to 24 V
is this just the Voltage Operating Rnage (input voltage) and I just can turn on a LED (3V) .... but noting above that voltage.

why is not possible to have similar voltage output, producing the mechanical movement?

I have read about the "disadvantages of a mechanical commutator" and about the "reversibility principle" (a little)... but I still don´t understand.
¿There are a converter or smart table to know how much output Voltage I can obtain from a typical motor?
... I Would like to have an output voltage of 12V from a motor-generator not expensive. (less than $100 dlls) Is that possible ?

KIND REGARDS!!!!

That appears to be a DC brushed motor, the voltage out should be proportional to the rpm, IOW, if the motor is rated at 24vdc and 2000rpm, back feeding the motor at this rpm, (2K) should produce `24vdc, or 1k for 12vdc..
