Gildemeister CNC Lathe

I am looking for a spindle motor for an older Gildemeister lathe. The motor is a 400v DC motor, 10kw. 260v field.

The info from the motor is:
GNA 160SV 827067
80-400-400 73
1.8-25-25
100-1350-4000
Err 260-260-64v 2.5-0.6
F23

I need this motor or anything that would take it's place. Mounting, pulleys, shaft size are all easily fixed or adapted. We could even adapt the encoder on the rear of the motor to another motor fairly easily.

If a replacement cannot be found I will need quotes to rewind the armature. The wires from the commutator shows burns on some of them. The rest don't show anything. The motor was running, then the drive failed. We rebuilt the drive and then noticed the marks on the motor.

Any help would be appreciated as I have a very expensive boat anchor at the moment. Thanks
