PURPOSE:To enable to arrange unit coils at the prescribed position accurately by forming a plurality of sheet-shaped printed coils radially disposed with a plurality of unit coils in a cylindrical tube shape. CONSTITUTION:A sheet-shaped printed coil 31 radially disposed, for example, with 6 unit coils 32-37 is formed by engaging the coil 31 with a formed shaft 41 which exhibits an inner diameter after shaping through the central hole, coating molding resin, and pressing from outside via an outer diameter die 42 which exhibits the outer diameter after molding. At this time, since the unit coils are coupled to each other, the mutual positions are accurately maintained, a position error does not occurs due to the irregularity in the thickness, thereby generating uniform torque and obtaining a motor having smooth rotation. |
