I am repowering a lathe, and I already have a motor from a GE stress test machine. I have the whole GE unit, actually. But driving the motor is a little above my current skill level. The electronics from the Stress test machine are extensive, as it includes an EKG and is normally controlled from a remote computer.
The motor data is at the bottom of the post
It would be nice to be able to vary the speed between 500 and 1500 rpm, but I would be satisfied to be able to just drive it around 1000 rpm. There is plenty of gearing selection on the lathe. In a simpler world, I could just hook the motor up to a power source with a fixed voltage, and it would turn at a fixed rate. The system as installed in the GE machine used 5 hall effect leads that seem to allow the driver board to apply voltage to the different phases of the motor to maintain constant torque, and to use powered braking.
Anyway, unless there is a cost-efficient off the shelf system available to drive the motor, I will at minimum need to reuse the motor driver box, and figure out how to give it the signals it expects from the main control board via a serial cable.
So, any help is appreciated.

If the motor plate image did not come through, the data is:
HP-3
RPM-4000
Frame-50HZ Ser.F-1
Volts-320 Amps-21.2
Insul F Amb-40C
Duty- Cont Encl-Tenv
Brg/De-6205 Brg/Ode-6205
