<p>PURPOSE:To increase the adhesive strength between sheet coils and the adhesive strength between coil pieces by employing as an insulator a thin plate coated with thermosetting insulating resin on an aramid fiber sheet. CONSTITUTION:A rotor 10 of a printed motor is composed by attaching a boss 12 and a rotary shaft 13 to the center of a coil 11. An insulator 15 is interposed between two coil pieces 14 to adhere therebetween by thermal press-adhering, and the piece 14 is formed by interposing the insulator 15 between sheet coils 16 to adhere therebetween. The insulator 15 used between the sheets 16 and the pieces 14 includes an aramid fiber sheet 15b coated on both side faces thereof with thermosetting resin 15c. Thus, it can prevent the insulator from cracking such as in a case where mica is used.</p> |
