PURPOSE:To simplify constitution of the titled detector without winding stators and rotors by providing permanent magnets on either iron cores of the stators or the iron cores of the rotors where magnetic field detecting sensors are situated. CONSTITUTION:The magnetic field detecting sensors 5a, 5b, 6a and 6b such as Hall elements, for instance, and the permanent magnets 7a, 7b, 8a and 8b are interposed in contact with mutually between both the iron cores of stators 1 and 2 where respective pole parts 1a, 1b, 1c and 1d, and 2a, 2b, 2c and 2d are situated. Then, the respective magnetic field detecting sensors 5a, 5b, 6a and 6b are made to detect the D.C. magnetic fields and the respective permanent magnets 7a, 7b, 8a and 8b are made to generate the bias magnetic fields. The constitution of the titled detector can be simplified without winding the stators and rotors by the above-mentioned constitution. |
