I am trying to find a replacement for it. ( After I hung a large wire
antenna system my XYL suddenly became nostalgic about the Isoloop). I do
not have any technical info about what motor is needed. I can probably
figure it out when I pull everything apart, but I wondered if anyone had
access to this information?

Check the winding resistance, and wether it's a bipolar (four wire) or
unipolar (more than four wires) If the replacement is mechanically fit, and
the same general resistance and scheme, you'll be fine.
