    • A stepper motor device has a stator and a rotor. The rotor comprises: a shaft; a rotor core associated with the shaft; and a magnet fixed to the rotor core. The stator comprises: a stator shell; a yoke disposed within the shell; a coil wound about the yoke and an end plate magnetically connecting the yoke to the stator shell. The coil is located beside the magnet in the axial direction of the motor. The stator has a number of salient poles, and the salient poles are arranged to face the magnet across a small air gap. The coil creates magnetic poles in the salient poles with a common polarity.
    • 步进电机装置具有定子和转子。 转子包括:轴; 与所述轴相关联的转子芯; 和固定在转子铁心上的磁铁。 定子包括:定子壳; 设置在外壳内的轭; 围绕磁轭卷绕的线圈和将磁轭与定子壳磁性连接的端板。 线圈位于电机的轴向方向的旁边。 定子具有多个凸极,并且凸极布置成面对磁体穿过小气隙。 线圈在凸极上产生具有共同极性的磁极。
