Abstract
The present invention provides a stator for motors in which a space volume occupied by the winding wire of an excitation winding section can be increased, thereby allowing magnetic flux to readily flow through the yoke. On an inner peripheral surface portion of the yoke, a pair of flat-surface portionsare respectively formed in the circumferential direction on either sides of six fitted recessesso that the flat-surface portions are continuous with the inner surfaces of the fitted recesses. The pair of flat-surface portionsare located on the same virtual plane and have a side of an identical dimension that extends in the circumferential direction. The inner surface of the fitted recessis constituted by a pair of inclined flat surfacesrespectively continuous with the pair of flat-surface portions. The first flange portionof the bobbin, which is in contact with the inner peripheral surface of the yoke, includes a flat plate-like bodyand a pair of ribs. With the excitation winding sectionbeing mounted onto the stator core, the pair of ribsare fitted into a pair of spacesformed between the yokeand the magnetic pole constituent member
