PURPOSE: A feedback loop control structure in a stepping motor is provided to facilitate easy control of angles and positions of the stepping motor, thereby preventing pulse loss. CONSTITUTION: A printed circuit board is disposed on the top of a magnet(70) which rotates by current applied to coils(81~83). The coils are formed at a surface of the printed circuit board to correspond to a certain position of the magnet and to be adjacent to a first pole of the magnet. |
