I'd call Baldor and Allen Bradley, in that order.
Get their tech support phone numbers. Allen Bradley may ask you for a
support contract number, just tell them you want to buy a drive for the
motor you have
and see what they say.
Baldor should answer the phone. Although they may try and direct you
to a Baldor distributor. I believe Baldor was selling generic servo
drives at one point to replace old obsolete drives. So they should be
willing to talk to you about that and give you some idea of possible
performance. Electrocraft was a big name in servos for a long time so
Baldor may want to help you with a replacement drive.
Baldor's prices have been fairly reasonable.

Baldor will not reply. Rockwell bought Reliance in the 90s. The
electrocraft products became Rockwell Automation Products (Allen Bradley)
Later Rockwell sold Reliance to Baldor but kept the Electrocraft stuff.

Thanks for the .pdf link.
I did send the details to Baldor (was ElectroCraft) and will see if they
bother to reply.
Yes, the low speed is confusing because it obviously has very low
inductance windings to get the instantaneous torque.
Ahh, maybe the rating is specific to the application since it's probably a
custom order. It had an 80mm spur gear that drove a 2m diameter ring that
sits around the patient. So one wouldn't want that spinning at a 1000RPM or
so.
I'll explore the drive. If I can get a direct/ and belt set-up with 1:1 and
1:3 I'll be quite happy.

I would find the original drive specs for that motor. I'm sure they
had
a matching drive for it.
I think it is a close relative of these:

The nameplate decoder at the back fits, to an extent.
Possibly S-6300 is a special?
I would be tempted to connect it to a drive and see what happens.
Others in the family with similar peak torque seem happy at 3000 rpm.
