induction motor speed control thesis

I have been researching this question for a few weeks. In particular I was trying to find a way (VFD) to convert a Midi-lathe to variable speed to eliminate belt changes to alter speed. I get conflicting information and I did find a vendor that sold a device to do this. However, using it on a capacitor start (induction motor) is in question. Some say when the motor slows down the motor switches between the start and run windings. Many people feel there is a power experience between AC and DC motors. (DC being more than bigger AC????) Many have converted their lathe to a DC motor and added some controls to get variable speed. You can buy variable speed lathes but many feel they are underpowered for anything but small work like pens etc. I don’t want to count on someone throwing away a treadmill to get a motor and then have to jury rig a controller. So is it possible to buy something to backfit an AC lathe and make it variable speed? Some kinf of VFD drive controller etcf?
