Abstract
A wheel speed sensor comprises a non-magnetic spindle, a rotor of magnetic material carried by the spindle, a stator surrounding the rotor, a permanent magnet, a stationary hub of magnetic material in which the spindle is rotatably mounted, and a wire coil disposed for induction by current by changing magnetic fields caused by rotation of the rotor. The rotor and the hub are superimposed over the total length of the rotor, irrespective of the relative axial positions of the rotor and the hub due to the end float of the spindle. This ensures that the effective length of an air gap between the overlapping faces of the rotor and the hub remains substantially constant irrespective of any such end float. Thus the resistance of a magnetic flux path across the air gap will remain substantially constant.
