Tom, The IPM will depend on the lead of the ball screw, typically 4 to 5 turns/rev i.e. 1 revolution will move you .25" for 4 lead screw. you just do the math.
VFD= Variable Frequency Drive, it takes the 50/60 cycles power optional single phase-3ph in and converts it to variable frequency 3 phase out up to 100/120 hz for operation on a standard induction motor.
effectively doubling the rpm of a standard 4 pole motor.
I will try and dig up the info on the Nook, BTW it includes the dogbone you need for the crossing of the ball screws. (they are made for BP but you may be able to adapt.)
