  • Patent number: 11713983
    Abstract: An inductive position encoder includes a scale, a detector and a signal processor. The scale includes a periodic pattern of signal modulating elements (SME) arranged along a measuring axis (MA) with a spatial wavelength W1. The detector comprises sensing elements and a field generating coil that generates a changing magnetic flux. The sensing elements comprise conductive loops that provide detector signals responsive to a local effect on the changing magnetic flux provided by adjacent SME's. Some or all of the conductive loops are configured according to an intra-loop shift relationship wherein equal “shifted proportions” of a loop are shifted in opposite directions by W1/4K. K is an odd integer. The intra-loop shift relationship can be used to suppress Kth spatial harmonic components in the detector signals, while also overcoming longstanding detrimental layout problems. It combines easily with “loop width” spatial filtering techniques that filter other spatial harmonic signal components.
