摘要： Disclosed is a rotational speed sensor comprising a rotatable ring, e.g. connectable to a bearing. The rotational speed sensor has K magnetic pole pairs distributed angularly over the rotatable ring. Also, sensor means are present positioned relative to the rotatable ring such that a varying magnetic field is detected by the sensor means. The sensor means comprise a first pair of magnetic sensors, the first pair of magnetic sensors being positioned 2πL/K radians apart from each other. The sensor means may further comprise a second pair of magnetic sensors, the second pair of sensors being positioned 2πM/K radians apart from each other. The first pair of sensors and second pair of sensors are positioned at a relative position of (2π/K)*((2n−1)/2) radians.
