Abstract
PURPOSE: To simplify the construction of a revolution speed detector, by providing a stator with a detection unit which comprises a coil and a second tooth-shaped part facing a first tooth-shaped part provided on a rotor.
CONSTITUTION: Numerous teeth 59 are provided on the peripheral part of a boss 26 of a rotor magnet 11. The frequency detection unit 60 is provided on the stator in the face of the teeth 59. The detection unit 60 comprises teeth 64 of the same pitch as said teeth 59, and the coil 55 provided around a bobbin 57 of U-shaped cross section.
