Abstract
A speed measuring sensing device for producing a signal corresponding to the relative angular rotation between two structural members including a rotor arranged on the rotating member and a stator mounted on the stationary member. The stator is separated from the rotor by an air gap. The rotor includes a plurality of magnetizable sectors which vary the magnetic field while passing a pole shoe of the stator. The surface area of each of the magnetizable sectors of the rotor and the surface area of the pole shoe of the stator exhibit a maximum ratio of 1 to 1.
