A linear actuator is an actuator that creates motion in a straight line﹐
in contrast to the circular motion of a conventional electric motor.
==>線性驅動器乃由驅動器產生直線方向的運動.對比於馬達是由圓周運動轉換成直線運動.

------------------------

Linear actuators are used in machine tools and industrial machinery﹐
in computer peripherals such as disk drives and printers﹐
in valves and damperts﹐ and in many other places where
linear motion is required.
Hydraulic or pneumatic cylinders inhetently produce linear motion.
==>線性驅動器常用於機械工具及工廠設備中.在電腦周邊中如磁碟機及印表機.在管路的閥門及閘板控制更是需要線性運動來達成.而液壓系統或氣動缸本質上就是用來產生直線運動.

------------------------

Many other mechanisms are used to
generate linear motion from a rotating motoe.
==>還有更多的機構常使用圓周運動來轉換成線性運動.
