Abstract
PURPOSE: To prevent the generation of vibrations by providing a magnet, a rotor, the first and the second stators in a certain arrangement and providing a generating coil in such a way to intersect with either of a magnetic path including the first stator and that including the second stator.
CONSTITUTION: A rotor 2 with many magnetic pole teeth in the circular direction and an exciting magnet 3 magnetized in the axial direction are provided on a rotor 1, and on a case 5 made of a soft magnetic material, the first and the second stators 4a and 4b each having magnetic teeth of equal pitch as that of the magnetic teeth of the rotor 2 are arranged alternately so that they may be a distance d apart in the axial direction and the magnetic pole teeth of the two may be shifted by half a pitch. And a generating coil 6 is arranged so that it may intersect with magnetic fluxes which pass through a magnetic path including one of the two stators, for example, the first stator 4a. By so doing, the magnetic fluxes of the magnet 3 are distributed to the first and the second stators 4a and 4b as the rotor 2 rotates, but as the total amount of the fluxes does not change, the generation of vibrations can be avoided.
