PURPOSE:To accurately and reliably couple fixedly a stator yoke and a stator pole pieces by inserting fixedly projections of upper ends of both side pieces of the yoke to the small holes of a stator pole teeth plate. CONSTITUTION:A flat magnet rotor 1 formed in a disc shape is alternately magnetized N, S, N, S,... radially from the center on the back surface. A stator pole teeth plate 2 and a stator yoke 3 engage projections 3c formed on both side hole surfaces of the yoke 3 with a plurality of long small holes 2d of both end of the plate 2, and bonded by calking the projections 3c. A shaft 6 is rotatably inserted to a bearing 4. A coil 8 is wound on a coil frame 7. |
