Not quite sure what you mean.
Most any motor can be wired at least two different ways, there will be combinations for voltage and rotation. Providing a couple of the common hooks with the motor is normal for most manufactures.

This motor could be manufactured for an OEM, the OEM may put their own tag on and that tag may not have the same information as the manufacture would.

The voltage still bugs me. Most DC motors like this are 90 or 180 volt. If it is an OEM...

If I were you, I would take the motor to a re-wind shop. There they can test and label the leads and tell you all you want to know about it.

Just be careful with DC voltage that high. In my opinion it is more dangerous than AC. Before a bunch of people start debating that I will say other than a personal ZAP or two, with AC there is the zero crossing thing. If you are lucky, that is when you can break free. DC has zero, zero crossing. Now I will get off the soap box

If it really is a DC motor and you need help with a driver, let us know.
