The shaft comprises or is coupled to an end portion that comprises a soft magnetic material, in embodiments, with the end portion having an end surface proximate the sensor that is rotationally asymmetric with respect to the rotation axis running through the length of the shaft. The sensor comprises at least three magnetic field sensing elements arranged in a plane generally perpendicular to the shaft and rotation axis. Circuitry forming part of or coupled to the sensor is configured to estimate a rotational position of the shaft by combining the signals of the at least three magnetic field sensing elements."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"On-axis magnetic field angle sensors, systems and method","description":"Embodiments relate to magnetic field sensors, such as magnetic field angle sensors with generally on-axis arrangements of sensor elements relative to a rotation axis of a magnet or shaft.
