    • A magnetic-controlled actuator (100) with an auto-locking function for joints of a manipulation arm mainly includes an inner-layer stator (10), an inner-layer mover (20), an outer-layer mover (30), an outer-layer stator (40), and a fixing shaft (50). The inner-layer mover (20), the outer-layer mover (30), and the outer-layer stator (40) have a plurality of permanent magnets, respectively. The fixed shaft (50) simultaneously penetrates through the inner-layer stator (10), the inner-layer mover (20), the outer-layer mover (30), and the outer-layer stator (40) forming a coaxial arrangement. The inner-layer mover (20) rotates relatively to the inner-layer stator (10) to output power from the actuator (100). Therefore, a cogging effect, which is produced due to interaction of the permanent magnets between the outer-layer mover (30) and the outer-layer stator (40), is automatically produces a high cogging torque for the actuator (100). Thus the actuator (100) provides a sufficient locking force to lock the non-stationary inner-layer mover (20) when a power failure occurs.
    • 具有用于操纵臂的接头的自动锁定功能的磁控致动器(100)主要包括内层定子(10),内层移动器(20),外层移动器(30), 外层定子(40)和固定轴(50)。 内层移动器(20),外层移动器(30)和外层定子(40)分别具有多个永磁体。 固定轴(50)同时穿过内层定子(10),内层移动器(20),外层移动器(30)和形成同轴布置的外层定子(40)。 内层移动器(20)相对于内层定子(10)旋转以从致动器(100)输出动力。 因此,由于外层动子(30)和外层定子(40)之间的永久磁铁的相互作用而产生的齿槽效应自动地产生用于致动器(100)的高齿槽转矩。 因此,当电源故障发生时,致动器(100)提供足够的锁定力来锁定非静止内层移动器(20)。
