Re: specs for Slo-Syn SS222E steppers

Found this:
The type number identification system for SLO-SYN Synchronous Motors
is straightforward and easily understood. For example, in type number
SS25, the "SS" indicates "Standard SLO-SYN", which has a synchronous
shaft speed of 72 rpm at 120 volts, 60 hertz. The "25" in the type
number designates the torque rating of the motor in ounce-inches.
Figure 4 shows the letter designations which are offered and
Figure 5 shows how the two elements of the type number identify the
characteristics of the motor.

This is a sync motor and you'd have to modify it to separate the 2
coils to use it as a stepper. Its probably made to run off 120vac
