Micro linear actuators, just like linear actuators, can mean different things for different people, basically because of their different applications and designs.
Generally speaking, however, micro linear actuators refer to a small device that converts rotary energy into linear motion. In this case, energy can be from different sources, including air, electricity, or liquid.
They work through different types of motion, such as pushing, pulling, clamping, and ejecting. It is basically the same with the concept of linear actuators, with the only difference being the fact that it is more compact.
The sleek profile of micro linear actuators makes them useful in various industries. Micro linear actuators are commonly used as a component of a motion-control system, often times controlled with the use of a computer, remote or phone. They are responsible for moving an object.
Micro linear actuators can be mechanical, electric, pneumatic, or hydraulic. They can be operated with different motors, and the choice of the latter will depend on the intended applications.
The applications for which to use micro linear actuators are endless. Among others, they can be found in machines and computer peripherals. Anywhere this is a need to create automation in a small space micro linear actuators can be an extremely useful item.
They can be installed in hard drives, printers, laser processors, and home automation.
They can also be effective for medical imaging and diagnostic technologies. Automotive, animatronics, robotics, solar, farming and construction industries will also benefit from the use of micro linear actuators.
They can also be found in toys and consumer appliances, among others. Many hobbyists, designers and artists find a need to create motion in their projects. Self-made RC construction vehicles and kits are a prime example of a common use of micro linear actuators.
Compared to traditional linear actuators, the biggest advantage of micro linear actuators would be in terms of size. Because they are compact, they take minimal footprint, but this does not mean that quality and functionality will be compromised.
Before these miniature versions of their larger predecessors came to market, many people would have to retrofit their projects with a DIY configuration of their own. These of course are never ideal as it’s very difficult (and expensive) to get the exact look, feel, motion and power necessary for the final project.
Naturally, the motors are much smaller size, however there are many versatile options in terms of size, shape and power. More so, it is also beneficial because of very low power usage.
Because of its clean, simple design, they also very lightweight and easy to mount into any application.
All of these things, however, will be dependent on the specific needs of your projects.
Choosing Micro Linear Actuators
Due to the precise nature of micro linear actuators, you will want to be very careful when selecting the right one for your project.
User-specific requirements, such as the expected application, will have an impact on the choice that will be made. You will need to determine the space you have to place the actuator as well as other factors including the weight of the load needing to be moved and the distance it needs to be moved.
Programmability will also be a vital consideration. Most actuators can easily be controlled using a simple switch, remote control, computer or phone. You may even want to create specialized motion where it will stop and start at a given point or command.
It should be made from exceptional materials that can be long-lasting. Environmental concerns and space availability should also be given careful thought when choosing your micro linear actuator.
