V i b r a t i o n r e s i s t a n c e i s 400 m/sec.² for the stator and 600 m/sec.² for the rotor. This ensures robustness as a motor feedback system—particularly when the motor is designed for high performance.

The system uses non-contact, capacitive sensors with nanometer resolution measure error motion in the machine and sur- rounding environment. Among other information, this includes intelligence on roughness, roundness, runout, vibration, thermal grow th and repeat- ability across the entire per formance range of machine tool. The company says that each of these parameters impacts the final dimensional capability of a machine and its ability to make a part to desired specification. Ultimately, measuring a rotational spindle can help confirm or eliminate root causes of problems, the company says. For instance, a shop could ensure that a new machine is not a lemon; that production is proceeding optimally; and that maintenance is used to determine the root cause of failures rather than just replacing parts.
