PURPOSE:To provide necessary strength of, to reduce the thickness of and to enhance the efficiency of a DC motor by employing as a stator insulator films printed with winding pattern by foils of conductors and laminated radially in a cylindrical shape. CONSTITUTION:A conductor film such as a copper film is etched and formed with a winding pattern 9 of a copper foil on a thin film 8 of insulator made of plastic or the like. A plurality of the films 8 are radially superposed to form a cylindrical stator 3. This thin cylinder 3 is used, thereby reducing an interval between the outside and inside rotors. |
