Abstract
PURPOSE:To simplify the construction of a revolution speed detector, by providing a plurality of revolution speed detecting magnetic poles on a rotor and providing a stator with a detection unit which consists of a coil and comb-shaped gaps and faces the magnetic poles. CONSTITUTION:The frequency detection unit 60 is provided on the stator in the face of magnetized parts 46 of a rotor magnet 11, which extend in the circumferential direction of a boss 26. The detection unit 60 comprises the gaps 48 which are defined by comb teeth 50, 52 and extend in the circumferentialdir direction, and the coil 55 provided around a bobbin 57 of U-shaped cross section.
