Abstract
A rotary position sensor comprises a magnetic sensor for generating two independent signals indicative of at least two different order magnetic fields, and a magnetic assembly forming a first magnetic field component having a first order at the location of the magnetic sensor, in which the first magnetic field component is rotatable relative to the magnetic sensor by receiving a first angle. The magnetic assembly is also adapted for forming a second magnetic field component having a second order, different from the first order, at the location of the magnetic sensor, in which the second magnetic field component is rotatable relative to the magnetic sensor and the first magnetic assembly by receiving a second angle. The position sensor comprises a processor for combining the two independent signals to produce a unique system state representative of the first and second angle.
