ABSTRACT:
An annular speed sensor especially adapted for motor vehicle wheel applications. The sensor utilizes an annular stator having a radial wall joining with inner and outer cylindrical walls, thus forming an annular cavity. An annular coil winding is fixed within the stator annular cavity. The cylindrical walls define teeth which confront a rotating magnetized tone ring to produce an alternating magnetic flux through the stator. One of both sets of stator teeth are deflected to increase the surface area of the teeth exposed to the tone wheel to produce better magnetic coupling between these elements.
