Cant recall where we were, do you have 3 phase power? If so is it just 230v 3 Phase?
Is the spindle drive you have dead?
 It does look like it is not a servo but rather just an AC spindle motor, it would still be a decent spindle motor if you have the drive for it.
Depending on your answer regards the 3 phase I may be able to point you to some motors and drives on Ebay that may do you. I have not looked recently but there are nearly always ones on USA Ebay.

You got it, 3 phase 230v.
The drives I have a monstrous (about 2'x1.5'x1'), filthy, and in unknown working condition, but I could do a car battery test on the motors and verify their working condition.  The encoder is also an issue because it is some wonky belt driven unit separate from the motor, and I am quite sure that they cannot be salvaged.

If I could keep the motors that would be ideal, but I assume that without the drive and functional encoder I could be SOL.

Thats  a shame that its just 230v 3 phase as it makes it harder to find a servo that will be similar specs to the  one you have.

You wont be able to test with a car battery as it is an AC motor.

Will have a search of USA Ebay and see if I can find anything that may be suitable for you but think the RPM will be the issue.

That was what I found when I called around, a motor capable of that wide of an RPM range gets pretty expensive.
The AC servo motors from china look physically identical unlike most of the induction motors I have seen, and have nearly the same specs as I found on my motor, but the information they sent me and the information on their website are conflicting, one says 220v 3 phase and the other shows 380v 3 phase...

I would say that is a dual winding AC spindle motor and not a servo. They are physically much bigger than a comparable servo.
Does your spindle fit via belt drive or is it direct, if belt then it may be possible to get a 3000rpm servo and gear 2:1

Just looking through the various pictures and I found a detail of the spindle driver "AC SPINDLE SERVO UNIT TYPE A06B-6044-H008" and the motor is "TYPE A06B-1003-B100"
I will look into those and see if it reveals anything else...

And of course to make everything super convenient, I have 2 different spindle controllers...

Scratch that, I have 3 different ones.  I see the A06B-6044-H008 on fleaBay, but I'm skeptical at best about buying a used 20+ year old driver for $1000+

Ok if it is an AC servo then it may be possible to use a different drive although you may need a different encoder as I think Fanuc use proprietary ones. You mentioned the encoder was via a belt but if its an AC servo then I think there will be an enoder on the motor itself and the one on the belt will just be for the control for spindle position.
