PURPOSE:To increase a rotary force and to reduce a cost by bonding a magnetic material split plate to the opposed surfaces of permanent magnets of a plurality of armature coils, bonding a magnetic disk on the surfaces of opposite side, and forming a frame of a nonmagnetic material. CONSTITUTION:In a flat motor in which a flat armature 2 and a permanent magnet 4 are opposed through an axial air gap, armature coils 34 are formed by winding conductive wires of foils 33 around a core 9, and split plates 35 made of magnetic materials are bonded to the opposed surface to the magnet. A disk 35 made of a magnetic material is bonded over the entire coil to the surface of the opposite side. Further, frames 6, 7 are formed of a nonmagnetic material, and a magnetic circuit is formed of a mounting plate 13, the magnet 4, the plate 35, the armature 2 and the disk 36. Thus, the frame can be formed of synthetic resin, and inexpensively assembled readily. |
