With the technique disclosed in Japanese Patent Application Laid-Open No. 149730, it is difficult to perform aligned winding with a high space factor. That is, in the coil bobbin 1 having the arcuate flange 15 shown in FIG. 16, the coil 5 is in contact with the end of the flange 9 at the time of winding, so that the winding is difficult to align and the flange 9 of the coil bobbin 1 is shown in FIG. It becomes such a linear shape. In this case, the cross section of the coil 5 becomes trapezoidal, and it is difficult to fit the coil 5 in the arc-shaped slot. Therefore, generally, a part of the stator core 2 is cut out as shown in FIGS. 18A and 18B, or the stator core 2 is formed into a polygonal shape as shown in FIGS. 19A and 19B. Needs to be done. When a part of the stator core 2 is cut off, a portion where the width of the stator core 2 is narrow is formed, so that there is a problem that the flow of the magnetic flux decreases and the characteristics of the motor deteriorate. When the stator core 2 is formed in a polygonal shape, the width of the stator core 2 is uniform, so that the influence on motor characteristics can be avoided. However, the outer diameter of the stator core 2 is reduced by the notch of the stator core 2. A problem arises that the motor becomes large and it is difficult to reduce the size and weight of the motor.

In addition, miniaturization and weight reduction are difficult.
