Abstract: PURPOSE:To facilitate positional management of a rotary magnet and a pole chip by extending each pole chip through a pole board arranged facing one end face of a coil in the axial direction of a rotary shaft, and other action. CONSTITUTION:Pole chips 21 are extended through pole boards 23a, 23b faced with one end face of a coil 22 arranged in the axial direction of a rotary shaft 12. When power is fed to the coil 22, all pole chips 21 are excited with same polarity. Consequently, rotary force is exerted onto a rotary magnet 11 through the center of the pole chip 21 which have been faced each other before power supply to the coil 22, the center of pole of the rotary magnet 11 and the centers of auxiliary poles which do not face each other. When the direction of power supply to the coil 22 is switched sequentially, the rotary magnet 11 can be rotated continuously. Magnetic force functioning onto the rotary magnet 11 is regulated by varying the number of the pole chip 21. By such arrangement, positional management of the rotary magnet and the pole chip is facilitated and the assembling manpower and characteristic fluctuation of product are reduced.
