I don't know if it would work that way or not?
First look how we need larger wire for 12V compared to 48V for the same distance. Or heavy switches for 12V compared to 48V.
So if we were taking 12V or 48V from a 180v brush??? Less watts but is it less wear?
I don't know how a brush really rides a comunicator. Is it like a car tire where at high speed you slide over the rough spots, but at lower speeds you feel every bump? So kinda like, High speed the brush jumps the gap and not much wear, but maybe lower speeds the brush feels the edges and gets chewed down more?
I just figure if I find them at the scrap yard for almost nothing. Use them for something
Now it ticks me off I was lazy the other day. I was driving down the road and saw a realy nice looking treadmill standing on end next to the garbage cans! Looked like a heavy duty metal frame and I bet it had a great motor too. But I was in my car and no tools. Was too lazy and short on time to worry about going back to get it so I drove on by. Now I wish I had stopped and asked to get it later with my truck. 8 of 10 times people will tell me to move something away from the cans and get it later with the truck if I need too. I could use the metal from that frame now, motor was probably good, and controls most likely worked. I geuss I had the same problem as most people who throw out treads mills, just too lazy! They were probably too lazy to use it, I was too lazy to go back and get it
