“…Rantatalo et al [6] employ Contact-less Dynamic Spindle Testing equipment (CDST) to analyze machine tool spindle vibrations. The CDST measures frequency response functions of a tool tip by exciting the rotor with electromagnets and determining applied force from bearing currents.…”

“…Operational speeds of 10,000, 11,000 and 14,000 rpm were considered. Similar to [6], Aenis et al [8] use AMBs to measure frequency responses for a centrifugal pump. An i-s (current-displacement) force measurement method using an inboard and outboard AMB is compared to results obtained from a reluctance network approach and a flux-based method requiring up to eight Hall sensor probes.…”

A System Identification Technique Using Bias Current Perturbation for the Determination of the Magnetic Axes of an Active Magnetic Bearing

Inherent in every Active Magnetic Bearing (AMB) are differences between the expected geometric axes and the actual magnetic axes due to a combination of discrepancies, including physical variation from manufacturing tolerances and misalignment from mechanical assembly, fringing and leakage effects, as well as variations in magnetic material properties within a single AMB. A method is presented here for locating the magnetic axes of an AMB that will facilitate the accurate characterization of the bearing air gaps for potential improvement in field tuning, performance analyses and certain shaft force measurement techniques. This paper presents an extension of the application of the bias current perturbation method for the determination of the magnetic center to the determination of magnetic axes for the further development of accurate current-based force measurement techniques.

“…Te-Yen and Lee [11] used it for modelling a conventional milling machine, Zhang et al [12] for a High-Speed milling machine and Lopez de Lacalle and Lamikiz [13] refers it as a standard technique for this task. The same technique is also considered useful for modelling elements that are particularly critical for final machining precision, such as Amaral et al [14] demonstrates for the systems for fixing the piece and Rantatalo et al [15] for spindles. Yang et al [16] have also studied FEM modelling of milling heads for optimising their design.…”
