Publication number: 20240133669Abstract: An apparatus comprises a target to rotate about an axis; an excitation coil to carry an excitation signal; and a first sense coil to carry a sense signal induced by the excitation signal. The first sense coil comprises two or more lobes in one or more planes that are perpendicular to the axis. The two or more lobes comprise a first lobe at a first position relative to the axis and a second lobe at a second position relative to the axis. The second position is substantially the same radial distance from the axis as the first position is from the axis. The second position is at an angular distance of ? from the first position, where ?=180°±?/2, and ? is a measurement range for angular-position sensing (e.g., ?=60°) within a range of 50% to 150% of ?.Type: ApplicationFiled: October 18, 2023Publication date: April 25, 2024Inventors: Ganesh Shaga, Kevin Mark Smith, Hwangsoo Choi, Surendra Akkina, Sudhneer Puttapudi

Publication number: 20220011138Abstract: An angular position sensor comprising two planar excitation coils forming a substantially circular interior area and two planar sensing coils positioned within a minor sector of the substantially circular interior area. Each of the two planar sensing coils comprises a clockwise winding portion and a counter-clockwise winding portion. The angular position sensor further comprises a substantially circular rotatable inductive coupling element positioned in overlying relation to the two planar sensing coils and separated from the two planar sensing coils by an airgap, wherein the substantially circular rotatable inductive coupling element comprises three, substantially evenly space, sector apertures.Type: ApplicationFiled: July 13, 2020Publication date: January 13, 2022Inventors: Ganesh Shaga, Kevin Mark Smith, JR., Hwangsoo Choi, Sudheer Puttapudi
