Re: Question for Kim Lux

Color me ignorant. But why would you over-volt your servos so much?
I run and sell Pittman's which are 24v motors, I can do 180 IPM
rapids and all that other stuff. So what will you gain? Up to a few
volts over isn't all the extra power just going to heat? Which
servos don't like.

Not that I'm attacking your position. If it works for you I wish you
all the best.

I'm just curious as of why?

Thanks
