(NEWBIE) How to use an (Fanuc) AC Spindle servo motor for an DIY CNC router

Okay i have found something.
In the Fanuc Manual .PDF (first link on the google link you have send (tommylight)) at site 42 "3. CONFIGURATION AND ORDER SPECIFICATION DRAWING NUMBER" reads "AC spindle SERVO unit". So, am i right when its an AC Permanent magnet motor?
On the same site i found "Spindle orientation control circuit" as "OPTIONAL" not "BASIC". Is that the "Encoder" ?

Guys, i can just ask you thousand of questions and speculate, but i think i will never be 100% sure what i need .

Do you have the motor? Can you actually touch ( well rotate by hand ) that motor?
If you can, then it is easy, find an LED light or multimeter or a torch light bulb, attach any of the items mentioned between two of the three motor wires and give it a spin.
If you get light or voltage, it is a PM motor, if not, it is induction.

Thanks for the explanation how to test it, but unfortunately i dont have the motor right now. Im just a bit in hurry not only because i want to start to learn solidworks, but also because the price is really good compared to the prices i found on ebay for the same model and i will soon visit my family in germany so i could pick up the motor while traveling, because its almost on same road. Im coming from germany (living in Poland since about 4 years), so i could make a call every moment and buy it already.
I havent even start with the drawings and that would be my first part for CNC router machine, but that would be a good motivation and i also want buy all parts step by step.

As expected its just a standard induction motor

Note that the encoder has no commutation pins (needed for a permanent magnet motor)

Besides spindle motors are almost always induction motors since they allow wider speed ranges
because you can do efficient field weakening for high speeds

Thanks for that!

Does it mean i can use an new VFD for that Spindle motor?

Do i need to replace the encoder with an newer one to do rigid tapping and use an ATC ?

Thanks in advance!

You should be able to use any suitably-rated VFD. If the currently-fitted encoder works then there is probably a way to interface it with LinuxCNC.
