Abstract
An inductive linear encoder configured to measure a relative position between two elements along a measuring axis direction includes a scale including a periodic scale pattern and a detector portion configured to move along the measuring axis direction relative to the periodic scale pattern, wherein the detector portion and the scale are separated by a gap. The detector portion includes a field generating portion configured to generate a changing magnetic flux, and a sensing portion configured to provide detector signals which respond to a local effect on the changing magnetic flux provided by adjacent signal modulating elements of the scale pattern. The encoder includes one or more actuators coupled to the detector portion and configured to be electronically controlled to adjust a position of the detector portion so as to adjust the gap based at least in part on the detector signals from the sensing portion.
