    Abstract: A motor driving circuit is applied to a motor unit, a pushrod unit, and a load unit. The motor unit is driven by the motor driving circuit. The pushrod unit is driven by the motor unit to lengthen or shorten. The load unit is pushed by the pushrod unit. A relay unit of the motor driving circuit is provided to brake the motor unit, thus raising the self-locking force of the motor unit when the pushrod unit lengthens to the maximum length or shortens to the minimum length, or the power supply is cut off.

    Abstract: A linear actuator includes a base having a positioning post and a motor fixed on one side of the base. A spindle positioning means includes a spindle, a seat and a fixing element. The spindle protrudes from the motor and penetrates the base. One side of the spindle away from the motor is formed with a free end. The seat includes a cylinder and an extension plate protruding outwards from the periphery of the cylinder. The extension plate is provided with a trough. The cylinder is connected to the free end of the spindle. The trough of the extension plate is located to correspond to the positioning post. The fixing element passes through the trough to fix the seat on the positioning post. Via this arrangement, the breakage of the spindle caused by a lateral force can be prevented efficiently.

    Abstract translation: 线性致动器包括具有定位柱的基座和固定在基座的一侧上的马达。 主轴定位装置包括主轴，座椅和固定元件。 主轴从电机突出并穿过底座。 远离电动机的主轴的一侧形成有自由端。 该座椅包括一个圆柱体和一个从圆筒周边向外突出的延伸板。 延伸板设有槽。 气缸连接到主轴的自由端。 延伸板的槽位于定位柱上。 固定元件通过槽将座椅固定在定位柱上。 通过这种布置，可以有效地防止由侧向力引起的主轴的断裂。
