步进电机及使用该步进电机的线性驱动器

Stepping motor and linear drive using same

Abstract

The invention provides a stepping motor, and further provides a linear drive using the stepping motor. The stepping motor comprises a stator and a rotator. The rotator comprises a permanent magnet; the stator comprises a shell and a plurality of winding elements, and further comprises at least one retainer; a central hole is formed in the center of the retainer and is used for accommodating the rotator; protruding teeth extending towards the center of the central hole are arranged on the periphery of the central hole, and are used for attracting a magnetic pole of the rotator and accordingly providing stop torque for the rotator.
本发明提供了一种步进电机,包括一定子和一转子,所述转子包括一永久磁体,所述定子包括一外壳及若干绕组组件,所述定子还包括至少一止动件,所述止动件的中央形成一中心孔用于容置所述转子,所述中心孔的周缘设有若干朝中心孔中央延伸的凸齿,所述凸齿用于与转子的磁极相吸从而对转子提供一止动转矩。本发明还提供了一种使用该步进电机的线性驱动器。
