Lathe motor conversion
I was giving a wood lathe recently (Vega bowl lathe). It has a 240v single phase 1.5HP motor in it. The only problem I have with it is the speed control is horrible. It's not a true variable speed, you just tighten or loosen the belt which creates slip and thus speeds up or slows down the headstock.
I've called the company and they offer a DC motor conversion, but it's very expensive. My question is, what would be the best route to go to get true variable speed?
With the motor I currently have I know I'm limited. Single phase (output) VFD's are way too expensive so I know I'm going to have to switch out the motor. I'm looking at either getting a three phase motor and a VFD (single phase in, three phase out), or a DC motor and speed controller. Can anyone offer any advice?
