Hi,
I have some stepper motors which I've so far been unable to find any specs on. I need to find out the voltage the motor is rated to and I have a theory on how it could be done.
Since the current draw is effectively regulated by the motor, all I need to deal with is finding the voltage (assuming the power supply has more than enough amps). Would it be possible to start with very low voltage and run the motor for a period of time until the motors temperature stabilized, repeating the process increasing the voltage by small increments until the temperature approaches the point getting excessively hot? Is this idea realistic?
