A variable reluctance rotation sensor comprises a rotatable magnetic toothed wheel adjacent a fixed magnetic pickup assembly. The pickup assembly comprises a pair of permanent magnets, each with a similar pole adjacent the wheel and separated circumferentially by the arc between a tooth and a non-adjacent slot. A magnetic flux member with a coil joins the other poles of the magnets in series opposed relationship and extends in close proximity to the toothed wheel to establish separate flux loops for each magnet distributed along the coil. The flux loops are spatially determined by the teeth and slots between the permanent magnets, so that they fluctuate circumferentially and generate an electrical signal in the coil with wheel rotation by variation of the flux linkages to individual turns of the coil. The sensor thus uses spatial flux changes to produce a rotation signal at very low rotational speeds with a larger air gap than that of conventional sensors.
