The Best Linear Actuator for RC

By | August 23, 2018

The Best Linear Actuator for RCHow much do you know about actuators? If you’re reading this article, then you’ve already appreciated some of the advantages of these devices. What makes them really powerful is their use in different industries, and today we’re interested in one specific branch: remote controls.

We’re going to analyze the market and help you choose the best linear actuator, but first we’ll step back and tell you about the device itself and some of its features. After all, it’s never too late to get back to the roots.

Linear Actuators and Their Advantages

The term “linear actuator” is easily understandable just from its name. Behind the word “actuator” hides a simple “mover”. So, such devices create movement in a linear manner, unlike actuators with rotary abilities. This is a very basic explanation, and if you want to know more, do research on the types of linear actuators.

Usually, there are two typical situations when using linear actuators is the only option. The first one is when you need a powerful lifting tool. The second one is when using rotation seems clumsy. For example, you have a robot that needs to move its hand. When you use a rotary actuator, parts of the robot’s arm are mounted to the output shaft of your device. This problem disappears when the linear tool is applied.

Summing it up, here are three main advantages of the linear actuators:

  1. Much higher lifting ability.
  2. The best device to develop a leverage.
  3. Smaller size.

The Application of Linear Actuators

Linear actuators are applied in all industries that are somehow related to machinery or automatization. We’re going to cover just several examples for a clearer understanding.

  • Agriculture machinery. Acceleration and stops of the main motors in harvesters and pulverizers requiere actuator work. Also, the amount of seeds for a specific field is regulated in seeding machines.
  • Construction machinery. Actuators are applied to stop the main motor, raise the stairs, or open doors.
  • Healthcare. Regulation of beds, wheelchairs, dental chairs, also necessary when constructing  Ray X tools.
  • Housing. Actuators are used to regulate mechanisms of windows or ventilation.
  • Marine. Regulation of TV antennas, doors, valves, etc.
  • Robotics. Applied to build any type of robot – all parts of the robot’s body are moved with linear actuators.
  • Remote controls (RC). Lots of custom variations are possible here, and they concern different branches: landing gears for aircraft or sliding awnings.

Our main focus is the last point from the list. It is especially important because remote controls are a wide branch touching on lots of industries.

Top 5 Linear Actuators for RC

 

To start working with a linear actuator, you’ll need an RC receiver, a source of power, and a linear actuator itself. We’re giving you five examples of the best devices for consideration.

Progressive Automations PA-07

Let’s start small. This is a microactuator that allows lots of flexibility within a limited space. It is easier to implement the device thanks to the low current requirement. PA-07 has a high environmental-protection rating which means that it can be used in many industries. The main ones are robotics and housing. To mount the device, you’ll need instruments designed for micro electric actuators.

Progressive Automations PA-14

This is a mini actuator, which means it’s able to produce medium lifting powers. PA-14 is also a great low-current solution if you work in a branch where size is an issue. The main industries where it can be used: housing, agriculture machinery, and robotics. For mounting, you will need to use tools created for mini actuators.

Progressive Automations PA-14P

This device is very similar to the previous one and also has mini parameters. Lifting abilities are still medium-powered, but this time you have a built-in potentiometer. It means that regardless of the object’s position, you’ll be able to control its movement with a high precision. In most cases, such precision is necessary in robotics and different types of machinery.

Progressive Automations PA-09

PA-09 is a small-sized industrial actuator. It is similar to PA-14, but it has a rod made of stainless steel and its powers are higher. The device works great with control systems of low voltage. Considering the features, PA-09 is applied in the marine, manufacturing, and robotics industries.

Progressive Automations PA-04-HS

Firstly, this actuator has a Hall Effect sensor inside. It allows precise control over objects. Moreover, if you work with several actuators at the same time, you can synchronize them with PA-04-HS. It’s usually used in robotics, housing (mostly in the furniture branch), and marine industry.

Additional Information on Linear Actuators

As you can see, there is no perfect solution for everyone. Depending on the industry you’re working in and on the specific branch you’re picking an actuator for, it’s necessary to learn more about the devices to make your choice. We gave you a general overview, and here’s some literature you can look through to dive deeper and get more knowledge on the subject.

  1. ‘Actuators: Basics and Applications’ by Hartmut Janocha. That’s where you should begin. The book will give you information on the properties of actuators, their current and potential application (link to the book).
  2. ‘Sensors and Actuators: Control System Instrumentation’ by Clarence W. de Silva. This book was initially created for students, so they could understand why sensors and actuators are so important for control systems. But any amateur in this field will also appreciate all the given information (link to the book).
  3. ‘Electromechanical Sensors and Actuators’ by Ilene J. Busch-Vishniac. This one is for you if you’re interested in mechanical engineering. The book is a part of the Mechanical Engineering Series and is presented by experts with narrow specialization (link to the book).

Conclusion

We hope it won’t take you much time to find what you need. Even if there are obstacles in your way, our team will gladly help you to overcome them. We also gathered for you a complete range of linear actuators for different purposes, including remote controls, so you’ll never get lost on the market.
