The surface is wound and installed with a sliding surface, which can prevent damage to the coil film or disconnection, and ensure the quality of the coil.

In addition, since the outer diameter sides of the four split iron core bodies b23 do not contact the inner diameter portion of the case 34, it is not necessary to precisely manufacture the shape of the outer peripheral portion of the split iron core bodies b23, and low-cost molds can be used, thereby rationalizing costs.

In addition, since the split iron core body b23 is attached to the four split iron core bodies a22 on which the coil is wound from the upper or lower axial direction of the motor, the shape of the split surface of the split iron core body a22 and the split iron core body b23 can be freely set. The shape can be selected to enlarge the contact area, and the magnetic resistance of the split surface can be reduced.
