It may surprise you to hear it, but knowing how to select the proper actuator is important. Because there are two major types of actuators: linear actuators and rotary actuators, the choice falls between these two lines.
While both types can be powered by electricity, electric rotary actuators are becoming more popular due to their high efficiency and versatility. I will cover some of the signs to recognize when you may need a rotary actuator rather than a linear actuator.
1. If You Need Continuous Rotation
One of the primary benefits of a rotary actuator is that it is designed for continuous rotation. It means that the actuator can rotate indefinitely in either direction, making it ideal for applications that require constant movement or course.
For example, an electric rotary actuator could be used to control the movement of a conveyor belt, rotate a solar panel to face the sun, or turn a valve in a piping system. In contrast, linear actuators are limited to a set range of motion and unsuitable for applications requiring continuous rotation.
2. You Need a Compact Design
Another advantage of rotary actuators is that they are generally more compact than linear actuators. It is because rotary actuators use a rotating motion to generate force, whereas linear actuators use a linear motion.
As a result, rotary actuators are more space-efficient and can be used in applications where space is at a premium. For example, a rotary actuator could be used to control the movement of a robotic arm in a small workspace or to open and close a damper in a tight mechanical room. An electric rotary actuator may be the way to go if you need a compact and easy-installation actuator.
3. You Need High Torque Output
Rotary actuators are also known for their high torque output, which makes them ideal for applications that require a lot of force. Torque is a measure of rotational energy essential for lifting, turning, and rotating heavy loads.
The rotary actuators can generate high torque levels, making them well-suited for applications that require a lot of force. For example, a rotary actuator could lift and transport heavy containers in a warehouse or turn a large gear in a manufacturing process. An electric rotary actuator is a good option if your system needs a high torque output.
4. You Need Versatility
Rotary actuators are also known for their versatility, which can be used in various applications and industries. Rotary actuators are used in many fields, from factory automation to medical equipment to aerospace and defense.
This versatility makes them a good choice for systems that may need to adapt to changing requirements or conditions. For example, an electric rotary actuator could be used to control the movement of a solar panel in a renewable energy system or to adjust the focus of a telescope in an observatory. If your system needs a versatile actuator that can handle a wide range of tasks, an electric rotary actuator may be the way to go.
5. You Need Precision Control
Finally, rotary actuators are known for their precision control. They can be accurately controlled using various methods, including electronic controllers, sensors, and feedback mechanisms. This precision control makes them ideal for applications that require precise movement or positioning, such as robotics, machine tooling, and manufacturing processes.
For example, an electric rotary actuator could be used to control the direction of a robotic arm in a manufacturing process or to position a camera in a security system. An electric rotary actuator is a good choice if your system needs an actuator that can deliver precise control.
Conclusion
In conclusion, there are several signs that you may need an electric rotary actuator rather than a linear actuator for your system. An electric rotary actuator may be the right choice if you need continuous rotation, a compact design, high torque output, versatility, or precision control.
While both linear and rotary actuators have their unique benefits, rotary actuators offer a range of advantages that make them well-suited for many different applications.
