I have a south bend lathe that i will probably put a VFD on it but.. If the motor has 10 ft lbs now,I am not sure what it has but makes the math easy, and I use a VFD for speed adjustment and keep full torque how does that get me the same torque as originally had? The reason i ask this is the motor originally had a set of pulleys and gears to change speed. This one has what looks like a 6:1 reduction in speed for low gear low speed use. So if i take my 10 ft lbs and multiply by 6 I have 60 ft lbs. With the VFD I thought all you get is full torque or 10 ft lbs. Am i missing something here??
