Abstract

An assembly includes a permanent magnet generating a magnetic field. The permanent magnet is arranged on the rotary member and generates a magnetic field perpendicular to an axis of rotation. A first channel has a first magnetic sensing element centered on the axis of rotation, the first channel providing a first angular data. A second channel has a second magnetic sensing element centered on the axis of rotation, the second channel providing a second angular data. The second magnetic sensing element is spaced from the first magnetic sensing element. Each of the first magnetic sensing element and the second magnetic sensing element have three voltage dividers. A processor computes a magnetic stray field component orthogonal to the magnetic field by comparing a first field strength based on the first angular data with the second field strength based on the second angular data.
