Ugh, these motors will have HORRIBLE performance. Maybe they could work for a tool carousel, but even there I think you might be disappointed. Just take a guess at the coil inductance, and you can see that it would take a long time for the current to ramp up.
My guess is these are 120 V synchronous motors, to be run off a 60 Hz 120 V AC line with a phase shift capacitor. They were developed by Superior Electric in the 1960's to run powerstats (Variacs) remotely from a lighting control board. They were called Slo-Syn motors. People found they made passable stepper motors for positioning use, and pretty soon a whole new industry popped up.
