ABSTRACT:
In the stage of winding a drive coil (17) on salient poles (114) in the assembling of a motor (1), the opening width of an armature core (11) is wide enough to allow easy and proper winding of the drive coil (17). After the winding of the drive coil (17), opening-width adjusting members (50A) are put within open slots (100), to thereby reduce the opening width of the armature core (11) at the flux gathering parts (54A) and (55A) of the opening-width adjusting member (50A). The opening-width adjusting member (50A) is positioned and fixed, by its elasticity, within each open slot.
