I thought about using a big stepper I have but it saturates at the rpm

all the wires are twisted together and the shaft spun the resistance
increases and then at a certain rpm drops dramatically. I suppose if
there were less poles in the rotor this wouldn't happen.

You are getting AC out of the servo - and poly phase at that. You need
some diodes to make them work properly. Tying wires together makes the
phases work against each other.
