Abstract: A magnetic rotary pulse generator for producing a speed signal in a vehicle as a direct function of a shaft or axle speed to operate speed indicating apparatus. The generator includes a rotor shaft having a rotor thereon coacting with a stator. A coil assembly includes permanent magnets for producing a magnetic field through the rotor and stator, and a winding in which a signal is generated as a direct function of the speed of the rotor. Coacting teeth in opposed relation are formed on the rotor and stator wherein the matching and mismatching thereof caused by the relative motion therebetween produces a pulsing signal output.
