る。Notches 15 and 16 each having a shape where a fixed position can be confirmed are formed on outer peripheral portions of the coil mounting printed circuit board 12 and the drive circuit mounting printed circuit board 13. The bottoms of the notches 15 and 16 are located outside the outer circumference of the stator yoke 11. Notch
15, 16 are provided in order to prevent the part 14 of the drive coil 4 from protruding from the outer peripheries of the coil mounting printed circuit board 12 and the drive circuit mounting printed circuit board 13. This reduces the risk of disconnection during assembly work. Further, the position of the part 14 of the drive coil 4 is fixed, and the workability is improved. In FIG. 1, a semi-circle is shown as the cutouts 15 and 16, but as shown in FIGS.
It may be formed in a letter shape or a Y shape. As a result, the fixing position of the part 14 of the drive coil is clarified, and the workability is further improved. The bottoms of the notches 15 and 16 are the stator yoke 11
Since it is located outside the outer periphery of the drive coil 4, the part 14 of the drive coil 4 is not in contact with the stator yoke 11. Therefore, no special insulation treatment is required for the part 14 of the drive coil 4.

工数は，従来に比べて減少する。One end 17 of the drive coil 4 that is connected to the drive circuit side
Is directly connected to the land 18 through the notches 15 and 16 and the outside of the stator yoke 11. By this direct connection, the number of copper wires 7 for connecting the coil mounting printed board 12 and the drive circuit mounting printed board 13 is only eight for the Hall element. Therefore, since the copper wires 7 concentrated in one place are reduced, the coil mounting printed circuit board 12 and the drive circuit mounting printed circuit board 13 are downsized. In addition, the man-hours for soldering are reduced as compared with the conventional method.
