Abstract
PURPOSE: To prevent tooth profile parts from bending and detection accuracy from becoming poor at the mounting of a detecting body and reduce the number of parts by integrally forming the detecting body by means of the material consisting in binding the powder of a permanent magnet material by a synthetic resin.
CONSTITUTION: Winding grooves 17 of a coil 13 and a pair of flange parts 18, 19 forming said grooves 17 are provided on the outside circumference of a detecting body 16 formed by binding the powder of a permanent magnet material by a synthetic resin, and further the tooth profile parts 18a, 19a for changing magnetic resistance by the opposing relation to the tooth profile part 14a of a rotor 14 are provided on the outside peripheral surface of the flange parts 18, 19. When the rotor 14 revolves, the magnetic flux passing the magnetic circuit of the tooth profile parts 18a, 19a of the detecting body 16 and the tooth profile part 14a of the rotor 14 changes, by which revolution detecting voltage is induced in the coil 13.
