What more info do you need? That really is about it. Do you need
specific holding torque? Wiring? You can figure out the wiring
with an ohmmeter. The two phases will have no conductivity between
them. If you find the 3 wires connected to a particular phase, then
find one wire that has roughly the same resistance to the other
two wires. This first wire is the center tap. Use it and one of the
others for each phase with a bipolar drive. The other end connection
is not used. Current will be 2.9A per phase either unipolar or
bipolar. A 60 V DC supply might be a good starting place.
