How do actuators and motors differ in hydraulic systems?

In hydraulic systems, the distinction between actuators and motors is fundamentally based on the type of motion each converts hydraulic energy into. Actuators are devices specifically designed to convert hydraulic energy into linear motion. This is typically achieved through cylinders that extend and retract to perform work, such as lifting or pushing loads in a straight line.

On the other hand, hydraulic motors are tasked with converting hydraulic energy into rotary motion. They facilitate movement in a circular motion, which is crucial for applications that require rotation, such as turning wheels or rotating shafts. This fundamental difference in motion types is what sets actuators and motors apart in functionality and application within hydraulic systems.

Understanding this difference is essential for selecting the appropriate component for specific tasks in hydraulic systems, as using an actuator when rotary motion is needed, or vice versa, would be ineffective and potentially damaging to the system.
