MUMBAI, India, June 26 -- Intellectual Property India has published a patent application (202617024146 A) filed by Firma Bourns, Inc.; and Mueller, Peter on February 28, 2026, for Inductive Position Sensor.
Inventor includes Mueller, Peter.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: A sensor (9) for sensing a rotation angle (22) of a shaft (7, 11) and a torque angle (16), which is dependent on a torque acting on the shaft (7, 11), wherein the shaft (7, 11) is divided into a first shaft section (11), a second shaft section (7) and a torsion element separating the first shaft section (11) and the second shaft section (7), comprising – a coarse track (18), which can be positioned circumferentially around the first shaft section (11) and comprises a coarse-track number, denoted hereafter by the formula symbol A, of coarse-track elements (29) arranged equidistantly in relation to one another; - a fine track (17), which can be positioned circumferentially around the second shaft section (7) and comprises a fine-track number, denoted hereafter by the formula symbol B and greater than the coarse-track number, of fine- track elements (27) arranged equidistantly in relation to one another; and - a sensing device (19), which is set up to sense the rotation angle (22) and the torque angle (16) from an angular position (34) of the coarse track (18) and an angular position (33) of the fine track (17) within a maximum torque-angle range, denoted hereafter by the formula symbol T, and a maximum rotation-angle range (51), denoted hereafter by the formula symbol S; - wherein the coarse-track number and the fine-track number are in a non-integer relationship to one another, characterized in that the coarse-track number and the fine-track number satisfy the following condition: formula (I), where the function gcd() stands for the determination of the greatest common divisor and the formula symbol T stands for the degree of a full angle.
