do with DC servo motors that weigh almost as much as he does? The

only learned Washington and DC motor weren't related a few weeks ago
and through this list, learned that a stepper had nothing to do with

You should be able to run it fine as a plain DC motor. There
are many variable speed controlers avaiable that can handle
the 220 volts at 10 Amps, more than the current expected with
these motors. The commutators would be wired in parallel and
with the same polarity and operated at 220 volts. Polarity
can be check by running one set at a time.
