Abstract
Sensor for continuously measuring the angular position of a shaft rotatably mounted relative to a housing. The sensor includes a stator, a rotor attachable to the shaft, and permanent magnets having alternating polarities located on a stator or a rotor capable of creating magnetic induction during the rotation of the rotor. A magnetic circuit channels the magnetic induction such that it is proportional to a sinusoidal function of the angle of the rotor. At least two electric transducers having linear output, each angularly offset one from the other relative to the stator, are located in the gaps arranged in the circuit. The magnetic circuit is toothed and includes at least one measuring unit having three teeth per pair of magnets, each tooth including a gap with a transducer.
