LinuxCNC generated resolver output

Thank you again! The option of using a belt-drive is pretty much not there. In addition any resolver which is self-contained tend to have a fairly low RPM range, so 1:1 at 10,000 rpm will most likely not happen.

I have looked at the Tamagawa and they do have the BRX series with a 38mm shaft mount which would make this all fairly easy. I believe I will go with that. I will make sure that I will ask the person if everything is included in the picture haha!

The ones I am talking about are where they have taken the resolver off of the motor and not noticed that they left half of it behind. A number of the BRX ones on eBay have photos where it isn't clear whether the inner spool is present or not.

Which Fanuc motor do you have ? Most Fanuc Ac motors are permanent magnet, which a standard vfd won't drive very well. Almost all the major drive manufacturers now make drives that support pm motors. The Hitachi WJ series work well and are inexpensive for what they are .

That is precisely why I am putting a proper spindle/servo drive on it rather than just VFD.
