If you know how to choose a micro linear actuator, then you’ll find it to be a very useful device for many applications. Choosing the right one is key to the success and longevity of your project.
There’s nothing more frustrating than getting all your parts together only to discover that they don’t fit or are the wrong specification for the job.
Because every application is different and there are many options to choose from, there are a few things you’ll need to know how to choose a micro or miniature linear actuator, before you buy.
How to Choose A Micro Linear Actuator: The 3 Most Important Things to Consider
- Weight – Force
- Size – Stroke/Travel
1. What is the weight of the object needing to be moved?
Force determines how much weight the actuator will be able to move or lift. If the object is heavier, your actuator will need more force capability. The downside of using more force is that it slows down the motion.
2. What is the size of work area and how far do you need the object to move?
Micro linear actuators are great because they can fit into spaces that most regular sized ones can’t. Our new line will offer a variety of sizes to help you get just the right fit.
Besides working area space, you’ll need to know the distance the object needs to move (Travel). The size of the actuator Stroke will tell you how far it’s capable of moving something.
3. How fast do you need to move the object?
If speed is important then you’ll need a micro actuator with a lower force and higher speed capabilities.
Remember that in order for an electrical actuator to function with speed, the object it moves must be lighter weight.
Refer to the specification tab on the product page to find out how fast it can move at full weight (Load). The heavier the object, the slower it will move.
How to Choose a Micro Linear Actuator: Other Important Things to Consider
- Duty Cycle
- Power Supply
- Working Conditions
How to Choose a Micro Linear Actuator: Putting it All Together
You may find that there is some flexibility in either weight, size or speed. Once you know your requirements, you may also want to consider the following:
- What option is the most important?
- Is there room for any adjustments in your application?
Hopefully these tips on how to choose a micro linear actuator will help you to make an informed decision when it comes time to make your selection.
Knowing that you have the right one for your application is critical because of the variety of available configurations. Choosing the wrong one could be a waste your time and money – or worse, could ruin your project and/or actuator entirely.
