9 Amazing Applications of the Rotary Actuators

It is a device that uses the principle of a rotating shaft to produce linear movement. It also shows different examples of how these simple devices are used daily. In this article, we are going to go over some of the amazing applications of rotary actuators that you can see all around.

It Can Convert Electromagnetic Force into Linear Motion

It converts an electromagnetic force such as electric, hydraulic, or pneumatic vibrations into linear motion. It is often used to convert mechanical energy from one form to another, for instance, into electricity. This way, It can help create electrical power and transmission systems.

It Is Like a Ring Representing Energy in Motion

A rotating shaft with a matched load converts mechanical energy into electrical or hydraulic power. The post can store and transfer mechanical energy into electrical or hydraulic energy.

It Can Convert Electrical Energy into Mechanical Energy

A rotary actuator converts an electrical current into mechanical vibration. The primary use for this technology is in starter motors, where an electric current is used to produce torque at the motor’s shaft and engage the gears.

It Can Control a Load Through a Circular Movement

It converts an input (electric, hydraulic, or pneumatic) into rotational motion at its output shaft. This motion can be accurately controlled by varying the input (torque) and allows the device to accomplish many tasks that would otherwise require complex drive mechanisms or multiple actuators.

It Can Transmit Power Over a Distance

They are widely used in power transmission systems, from trucks to computer hard disk drives. It is part of the motor and is commonly called a cam plate, or cam follower plate, of the movement it makes around its central axis. The cam plate moves linearly by sliding on two “ends” and one circular “edge,” which all rotate together around its central axis.

They Are Capable of Dynamic Motion in Both Directions

Rotary motion can be generated using electric or hydraulic energy (the most common type) or mechanical energy (the less common type). In the same way, rotary motion can go in both directions.

It Can Produce a Multitude of Motions

They can produce numerous motions and efficiently handle high torques, significant pressures, and high speeds; therefore, they have been widely used in many fields.

There Are Essentially Two Types of Rotary Actuator(s)

Cam-Follower and Sleeve-Follower. Both of these types are used for specific applications and problems being solved. Each type has its advantages and disadvantages, so it is essential to know about both to understand how it works.

A Rotary Actuator Can Be Made With Two Shafts and Two Cams

This type of “cam-follower” is often used for problem-solving and producing an extensive range of motion. These have only one shaft, translating the input (torque) into rotational motion at the output shaft. For example, it might open and close a valve control valve or steer an airplane. This type is often called a Linear Pulley because its output shaft is connected to another pulley that produces motion in another direction than the one laid out by the input rotation. (The output speed, in this case, would require a second pulley. This type of rotary actuator is also called a linear positioner.)

To enclose the cams, a Rotary Actuator can be made with two shafts, two cams, and a belt – or chain. This type of “sleeve-follower” is often used for producing high-speed and high-torque motions; these have their shafts connected by a belt or chain, which generates movement in the direction it wraps around the circumference of its outer ring.

The Bottom Line

There are many applications, some unique, while others can be found in everyday life. Knowing the essential characteristics of these devices is necessary so you can use them to solve all kinds of problems. At first glance, the invention is quite simple; however, it has many significant applications beyond what you might initially think. With this guide, you can learn how to use this fantastic tool and the ways in which it can be used.
