Hi John, nice score. That looks like it has the 4 speed motor head, basically four motors in one and there is a big selector switch to give you the four different RPMs. They are strictly 3-phase, so you'll need that or a phase converter to run it. The downside for these for turning bowls is the lowest speed is kind of fast. But, you may make it up with overall mass. As others have mentioned, a VFD might be a handy upgrade for speed control. In the past, VFD's were not recommended for antique motors as the insulation on the old motors might be compromised by transient voltage spikes from the VFD. Newer and better VFD's have minimized the voltage spikes and they can usually be safely put on old motors. You might also find the pattern makers carriage clumsy compared to a conventional woodturning lathe banjo, but you can probably retrofit an existing banjo if you wish.
