Haven't been following his thread, but saw this about the resolvers, we use the R11 form factor, with 1/8" input shaft, from AMCI, and they are $249.00 all day long, and in stock. Not too sure about the hollow resolvers that would mount on a motor shaft though. We have those on some Kollmorgen servo motors on one of our VMC's, those run about $1100.00 a piece :(
And the Resolver inputs on a 7i49 create a index pulse for threading and tapping, All the machines I have done so far, all have had resolvers.
