What is a Micro Linear Actuator?

Posted on Posted in Technology

Linear actuators have been used across industries for decades. Basically, they are components that convert rotary energy into linear motion. They make things move in a straight line, either sideways, forward, backward, upward, downward, or diagonally. Uses for large actuators include construction machinery, drilling machines, large home appliances, processing equipment, computers, and farming equipment. An actuator is versatile because it can use different sources, such as liquid, air, or electricity, and can utilize different motions, like pushing or pulling, ejecting, and clamping. Motors vary as well, and can be hydraulic, electrical, mechanical, or pneumatic. The size and design depend on the application, as does the type of motor.

A micro linear actuator is a much smaller version of traditional actuators. it can create automation, or motion, in small spaces. As technology advances and the demand for smaller products increases, actuators have to be developed to fit the needs. Computers, for example, in recent history have gone from large desk top machines to laptops to tablets. Printers, hard drives, and laser processors are also getting smaller. Electronic devices are getting smaller, thinner, and easier to carry. Cell phones are another example of items getting smaller. Drones, robotics, and gadgets are also getting smaller to accommodate delicate tasks, increase capacity, and be used without being detected or interfering with surroundings. A smaller drone, for example, can fly faster, farther, quieter, and often go unseen. Medical instruments and diagnostic equipment are also benefiting from smaller sizing and more sensitive responses to commands.

Hobbyists, designers, and artists are using small actuators in models, creations, and inventions. They are used for innovative projects, schools science fairs, and model building. Some of the most popular toys and gadgets on the market today are miniature moving items. They are also included in many modeling kits and building sets. Traditionally, people had to modify large actuators to fit small spaces, which compromised performance, smooth motion, and efficiency. Today, micro actuators are available that are lightweight, use little power, and are easy to mount or fit into projects. Companies are improving on micro actuators as technology advances. New versions are developed constantly and are being added to the marketplace on a regular basis.
