ABSTRACT:
Disclosed is a rotational speed sensor comprising a rotatable ring. The rotational speed sensor has K magnetic pole pairs distributed angularly over the rotatable ring. Also, sensors are positioned relative to the rotatable ring such that a varying magnetic field is detected. The sensors comprise a first pair being positioned 2πL/K radians apart. The sensors further comprise a second pair being positioned 2πM/K radians apart. The first pair of sensors and second pair of sensors are positioned at a relative position of (2π/K)*((2n−1)/2 radians. L, M are integers between one and K and n is an integer greater than one.
