Hey all, I got a new to me knee mill and am wanting to put a VFD on it. How ever I have a few questions first. The slowest speed on the mill now is 270 rpm, and I would like to get it down to around 100 rpm or so for using it to drill large holes. I have done a little bit of research and have come to find that the slower the speed of the motor the less torque it has. The mill has a 1.5hp motor on it now, would it be a good idea to install a larger motor to not have to worry about stalling it out? What kind of motor and VFD should I get for it?
