Abstract
PURPOSE: To provide a frequency generator which can detect high frequency with a simple construction by providing a standard tooth form on one of rotor and stator formed of resin molded magnetic material and a plurality of layers of a tooth form in different phase on the other thereof.
CONSTITUTION: The cylindrical portion 4a of a yoke 4 is inserted at an infinitesimal gap into the central hole 2a of a cup-shaped rotor 2 of resin molded magnetic material fixed to a shaft 3. There are provided a winding 8 mounted at the periphery of the cylindrical portion 4a and a ring-shaped stator 1 of resin molded magnetic material through a ring-shaped magnet 5 at the peripheral edge thereof. There are also formed a tooth form 7 of predetermined pitch, for example, on the inner peripheral surface of the stator 1 and teeth forms 6a, 6b having phase difference of 180° each other at the same pitch as the tooth form 7 on the outer peripheral surface of the rotor 2 facing oppositely at an infinitesimal gap from the tooth form 7. Thus, the winding 8 can produce a twice frequency detection signal of the frequency determined by the number of teeth of the tooth form 7 of the stator.
