This is another one of my "out of curiosity" threads.
Quite some time ago I remember reading a short mention that it is good to power a DC motor with 10 or 20 times the rated voltage and current limit it.
Firstly: did this person know what they were talking about?
Secondly: I can see the logic in using higher voltage and lower current however how would this current limiting be achieved? I doubt a PWM would be what they were referring to.
Thirdly: voltage, I would have imagined that if you go that far out the specs you may have trouble with using such a high voltage on windings that were not built for it. What kind of voltage can the thin enamel on magnet wire stand? I would also suspect that other problems may occur.
What do you think about this?
