PROBLEM TO BE SOLVED: To surely insulate the conductor pattern of a motor substrate and a stator core by providing an insulating printed layer silk-printed on the surface of an insulating layer, coating the conductor pattern at the section where the motor substrate and an auxiliary core plate overlap each other. SOLUTION: At the section where a motor substrate 10 and an auxiliary core plate 12 overlap each other, an insulating printed layer 19 is formed by silk printing on the surface of an insulating layer 18b, coating a conductor pattern 17 formed around a screw-tightening hole 10b. Since the printed layer 19 is formed by silk printing, the insulating layer 18b is not scratched by the auxiliary core plate 12, and no short circuit occurs between a stator-core 13 and the conductor pattern 17. In other words, the insulating property of the conductor pattern 17 can be improved, because the pattern 17 is not only coated with the insulating layer 18b, but also with the printed layer 19, in the part of the section where the substrate 10 and core plate 12 overlap each other, such as the circumference of the hole 10b where short-circuits are apt to occur. |
