Does anyone know how to tell the hp of a motor by measuring the iron stack of the rotor. Someone told me there is a way to compute it. Just curious
Never heard of it before but apparently it's true - see page C-3:
B.O. = B.S.
You can also figure it by motor weight or motor volume but the link above is probably more accurate than either of these two methods.
Thanks snewman I knew I had heard it or seen it somewhere just couldn't find it anywhere
