ABSTRACT:
After a coil 24 is wound through an open slot 26 which forms a sufficient space for the winding operation of an armature core 10, a magnetic member 34 is inserted and mounted into the open slot 26 and is then engaged with and fixed to the umbrella portions 20 of the armature core 10. A gap 36 formed in the central portion of the open slot 26 operates to narrow a gap between the magnetic poles of mutually adjoining salient poles 16, which reduces not only the generation of cogging phenomena and vibrations but also variations in quality between products, that is, the armature cores 10 produced.
