What Is a Rotary Actuator and How Are They Used?

You see it turn. You see it stop. You see it go.

That is a 로터리 액추에이터 at work. I make this clear for you. I keep it simple.

I. The Power of Controlled Rotation

You want things to turn on cue. You want safe moves. You want speed. You want 정도.

A rotary actuator gives you rotary motion that you can trust. It turns with 토크. It turns at a set rotational speed. It holds a set angular displacement.

I work with motion all day. I help you pick the right tool. I help you win on 자동화 시스템 그리고 process control.

II. What Is a Rotary Actuator?

A rotary actuator turns energy into a turn at the output shaft. It may use air. It may use oil. It may use 전기 모터.

• 에이 pneumatic rotary actuator uses pneumatic pressure.
• 에이 hydraulic rotary actuator uses hydraulic pressure.
• 안 electric rotary actuator uses electric voltage.

Some give limited rotation like a quarter turn actuator 또는 multi-turn actuator. Some give continuous rotation.

You pick by needed 토크 출력, rotation angle, speed, and power source.

III. How Does It Work?

그만큼 actuator working principle is simple. Energy moves parts inside. Parts like 피스톤, vanes, racks, pinions, gears, 그리고 기어박스. That push turns the output shaft. That turn moves your machine.

• Pneumatic: air acts on a piston and cylinder mechanism 또는 vane type body.
• Hydraulic: fluid acts the same way yet it gives more power transmission and high 토크.
• Electric: a motor drives a gear drive actuator 또는 linkage mechanism actuator. It can be AC or DC. It can be a servo rotary actuator 또는 stepper rotary actuator.

You can add 위치 피드백 ~와 함께 position sensors 그리고 리미트 스위치. You can add control signals from a PLC (Programmable Logic Controller) 또는 HMI (Human-Machine Interface) 또는 SCADA (Supervisory Control and Data Acquisition). You can use solenoid valves to switch air. You can use control systems to guide angular velocity and stop where you want.
