    摘要: A disc chucking mechanism includes a turn table 3 on which a disc 19 with a center hole 20 is located, a chucking magnet 10 for magnetically attracting a center hub 21 of the disc 19 to it, and a magnet yoke 60. The magnet yoke 60 includes a ring-like member which is inserted between the turn table 3 and the chucking magnet 10, engaging portions 62 which are extended from the ring-like member of the magnet yoke toward the turn table 3, and brought into engagement with the turn table, and magnet engaging portions 61 which are extended in the direction opposite to the bending direction of the engaging portions 62, and urgingly fix the chucking magnet 10.

    摘要: 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.

    摘要: 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.
