摘要： A low-profile stepping motor has a stator assembly structured such that first and second coil units are disposed flush with each other horizontally and are sandwiched between upper and lower stator yoke pieces each comprising first and second stator yokes which are punched out integrally with each other, are shaped symmetrically, and which each have a plurality of pole teeth along its semi-circular inner circumference. The upper and lower stator yoke pieces are fixedly put together by means of two studs lodged fittingly inside respective bobbins of the first and second coil units such that the studs have their both ends tightly engaging with holes formed in the upper and lower stator yoke pieces, whereby the coil units are surely held between the upper and lower stator yoke pieces.

摘要： In a motor, a shaft passes through a magnet of a rotor and is fixed to the magnet by way of a rotor sleeve formed by resin-molding between the magnet and the shaft. A resin-molded boss is fixed to a front end of a stator, has a center hole, and defines an inner surface continuous from the center hole and beveled so as to obliquely face a front end of the rotor sleeve. A plurality of bearing balls are rotatably disposed between the front end of the rotor sleeve and the beveled inner surface of the boss, thereby constituting a ball bearing which rotatably supports the shaft. Thus, the shaft is prevented from bowing, whereby the motor achieves a high rotational accuracy of the shaft without an additional bearing attached separately.

摘要： A low-profile stepping motor comprises: an upper twin-stator yoke plate composed of first and second upper stator yokes; a lower twin-stator yoke plate composed of first and second lower stator yokes; first and second coil units fixedly sandwiched between the upper and lower stator yoke plates so as to be arranged horizontally flush with each other; and a rotor assembly including a cylindrical magnet and disposed between the first and second coil units. In the stepping motor, one of the upper and lower twin-stator yoke plates is structured such that one half of its pole teeth partitioned in half by a predetermined datum line and open spaces each residing between two adjacent pole teeth of the other half are positioned symmetrically about the predetermined datum line, whereby the one twin-stator yoke plate can be used in common to the other twin-stator yoke plate.

摘要： A stator structure of a claw-pole type stepping motor which has an outer stator yoke having a plurality of pole teeth; an inner stator yoke having a plurality of pole teeth which are intermeshed with the plurality of pole teeth of the outer stator yoke with a gap therebetween; a coil disposed around the circumferential periphery defined by the pole teeth; and a covering which covers the coil. The stator external walls are only partially formed so as to allow the covering to be exposed in regions where the stator external walls are not formed. The stator structure of the present invention enables a dimensional reduction in size of a motor by a dimension corresponding to double the thickness of the stator yoke material, without impairing the performance of the motor.

摘要： A claw-pole type stepping motor which includes a stator in which coils are arranged in association with a pair of inner and outer yokes and a pair of pole tooth sections thereby forming a magnetic circuit; and a rotor magnet which is rotatably disposed opposite to the pair of pole tooth sections, each of the pair of pole tooth sections being prepared discretely from each of the inner and outer yokes by punching out a soft magnetic steel plate so as to form a piece having a belt portion and a plurality of pole teeth integrally connected to the belt portion and thereafter rolling into a cylindrical shape. Thus, it becomes possible to set arbitrarily individual dimensions of each of the pole teeth as required by the characteristics of a motor, thereby providing an excellent high output and miniature motor.
