Re: [CAD_CAM_EDM_DRO] AC Servo Motor/Drive Specification

Lots more complicated than that. The number of windings, current capacity,
back EMF (related to strength of the magnets and turns ratios), winding
resistance, and rotor inertia are all part of the minimal problem. To
further complicate issues many of the drive manufacturers use proprietary
feedback schemes. Basic feedback is a hall effect rotation sensor, but
wide variation exists.
