PROBLEM TO BE SOLVED: To solve the problem that in a conventional direct-drive motor, the number of poles of winding is increased, and a mechanical structure and an electric circuit are complicated, thereby hindering the manufacture and increasing the price. SOLUTION: Two pairs of one or small number of winding mechanisms which magnetize many winding poles, are arranged adjacently on the central axis, with a shift in the direction of its rotation by half the distance between the centers of adjacent poles. The mechanical structure of the motor, the electric circuit, and the manufacture process are simplified. COPYRIGHT: (C)2009,JPO&INPIT
