ABSTRACT:
There is described a speed sensor that is particularly adapted to moving vehicles such as automobiles. A permanent magnet, stator assembly, and field coil are held within a cup that is adapted to mate a bearing assembly of a non-driven wheel of the vehicle. A magnetic flux is provided by the permanent magnet and when rotor poles carried by the bearing assembly rotate in close proximity to the stator assembly, the magnetic flux in turn generates an alternating voltage current in the field coil. The alternating current so generated is then fed through an electrical terminal to a vehicle computer.
