It is a pretty standard 6 wire 200 step stepper motor. What do you want to know that the label doesn't tell you. If you want to wire it to a bipolar drive you have two wiring options, either half coil (basically the same electical specs a as what it would have been when used with the old unipolar drives and you only use 4 wires, the center tap and one end.) or series wound, still only use 4 wires, but this time you use both end leads and the center tap is not connected. Often the half coil wiring option will give the best performance.

Thanks for your reply.
The informaciĆ³n i need is the motor torque. The label doesn't have this information.

Probably wouldn't matter anyway, the natural magnets in those old round steppers fade over time, and it likely wouldn't meet it's specs any more. If it is a NEMA 34 double stack motor it is (or should be) right around 400oz-in holding torque (but as with all steppers that drops off precipitously with RPM).

Here is a link to the Pac-Sci catalog pertaining to your motor, (see pages 61 and 63)
www.cncitalia.it/upload_ele/PacSciDS.pdf
Looks like you might be lucky and your motor may have 8 leads. If so you'd have the 3rd option of wiring it parallel as well (often best if your drives can handle the current).
torque rating in that pdf are 314oz-in unipolar and 445oz-in series/parallel.
