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 cup shaped base 12 and a cap 13 are coupled, therein coil spring 14 is accommodated to form a holder 11, and the holder is interposed between the bearing 3 of a rotor shaft 4 and a sleeve 5. Different from being directly mounted on the rotor shaft, since the base 12 is provisionally held on the rotor shaft, the operation efficiency at the time of assembling the motor is outstandingly increased.
