This is NOT a CNC-type servo motor. It is a split phase/capacitor motor.
It may have
been used in one of those old chart recorders that ran one motor phase on
line voltage with a capacitor providing phase shift (your 100 V), and the
other winding was powered by the servo amplifier with a varying AC
voltage either in phase or 180 degrees out of phase with the line.
These are not likely to be of much use. Their time response from stop
is very slow, and the power output is usually just enough to drive a pen
across paper.

What good is a 2 Watt motor? That will move clock hands nicely, which
is probably about what it did in some airplane, which was to move hands
on an instrument in response to some distant sensor.
