If the motor is a 440V 3phase Y motor an electrical motor repair shop can take it apart enough to change a few wires around making it into a 240V 3phase 𝝙 motor that you can run off a 240 single phase to three phase VFD. A good industrial electrician can do the same if you know one. Residential wire tuggers, not so much. Then you have a lathe that you can change speeds with the turn of a dial instead of belts and the pulley arrangement you use now. At most you would switch the pulley to start working with a big, heavy or out of balance blank to get the most low speed torque, changing to back when the roughing work is done.Pete
