That is, as shown in FIG. 5, spirally wound flat coils 22 to 27 are arranged concentrically on a substrate 20 at equal intervals by adhesive, and two coils at symmetrical positions with respect to the center are connected in series. An armature coil is constructed by connecting the terminal portion 21 and the starting and ending ends of the coil. Connections between the coils of the armature coils and between the coils 22 to 27 and the terminal portion 21 are performed by a conductor pattern 20a formed on the substrate 20, and the coils 22 to 27 are connected to lands 28 provided on the conductor pattern 20a. The starting end and ending end are connected.

In addition, a large number of conductor patterns 20a are arranged side by side on the board and many lands 28 are provided, so a wide space is required, and dimensional accuracy of the outer diameter of the coil is required. be done. Furthermore, as the number of coils increases from 8 to 10, the number of lands 28 and the number of conductor patterns 20a increase, which requires more space for routing and land 2 days, and there is a risk of wire breakage or short circuits. Sexuality also increases. Also, since the wiring is crowded, it is difficult to solder the beginning and end of the coil, which increases the assembly time and results in a cost-intensive process.
