It may not have any markings but a photo would show what it looks like. Also what connections it has ie 2 or 3 power cables, any sort of encoder etc? And a pic of the motor drive itself would also help. What makes you think it's the motor and not the drive that has gone?

If the dead machine has 3 phase connections, you won't be able to fit a brushed motor. That should be fairly quick to spot. But there are people here who are familiar with these machines (not me) who may have some useful experience.
