Abstract

PURPOSE:To reduce the size of a coreless motor by associating a gear reduction machanism by utilizing a gap between a cup-shaped coil and a magnet in the coil. CONSTITUTION:A cup-shaped coil 2 is arranged in a cylindrical yoke 5, and a magnet 4 is arranged in the coil 2. A gear 14 to become a solar gear is arranged on the inner surface of a flange 3 of the coil 2, and an inner gear 10 is arranged at the side opposed to the flange 3 of a magnet 4. A planetary gear 9 is interposed between a gear 14 and the gear 10. The rotation around the gear 14 of the gear 9 is produced as the rotation of an output shaft 1 inserted to a supporting plate for supporting the shaft 14 of the gear 9.
