In a perfect world, an electric motor would power an actuator to supply motion to auxiliary equipment. This actuator is powered by electrical current rather than mechanical means. For the most part, electric actuators include a gear system that allows the actuation arm to be extended or retracted. Electrical actuators are often favoured over their pneumatic, hydraulic, and mechanical counterparts. The following arguments explain why. Engineers choose actuators for motion control applications across a variety of industrial industries.
Purposefully uncomplicated: Actuators, as opposed to hydraulic or pneumatic ones, have a more straightforward design and need fewer replacement components, making them both easy to maintain and very reliable. Electrical linear actuators are significantly more straightforward to incorporate than hydraulic or pneumatic solutions: microprocessors and programmable controllers in the former run most cutting-edge manufacturing equipment.
Why Do You Need Actuators, and What Benefits Do They Provide?
- Actuators are well-known for their superior accuracy in motion control. This is so because it allows for dynamic velocity, torque, and force adjustments as the action progresses.
- Superior in terms of safety, actuators cannot leak or get contaminated like their hydraulic counterparts. For these reasons, actuators are preferred.
- Electrical actuators are more cost-effective than their mechanical equivalents over time.
- There are also more advantages: The assembly of actuators is simplified using quick-connect wires and cables. In addition to being smaller and less noisy during operation, they are also more convenient.
An electric linear actuator is a standalone machine that, once installed where motion is needed, is linked through a thin wire to the system controller. When compared to similar products, it has substantially less space needed. It allows for more creative actuator placement options. However, a hydraulic actuator system with the same characteristics would often cost more due to the more significant number of components it requires.
Combining Into Existing Systems Easily
In addition to being simple to install in a building, electric linear actuators also play well with others in terms of integration. It is far simpler to program the orders to the controllers that govern the equipment in the facility than using a hydraulic or pneumatic system.
A disaster is unlikely if a skilled operator is in charge, but it’s always wise to take preventative measures. Electrical linear actuators excel in this application. Limit switches are standard on most actuators. When the complete range of motion has been attained, they are supposed to notify the driver to halt it. When a machine hits its limit, a limit switch will turn it off to prevent it from stopping unexpectedly. If it stops working, the motors will keep running until they are destroyed.
Electric linear actuators cannot be powered by any other than electrical current. The healthcare and medical sectors favour this type since it does not introduce contaminants into their processes. High-pressure fluids travel via hoses in hydraulic systems. Therefore, such systems need regular maintenance. Product or facility contamination is risky if even a single component fails. On the other hand, Pneumatic actuators use compressed air that might release harmful pollutants into the atmosphere.
Electric linear electric actuators currently exist in various sizes thanks to technical advancements. Still, they’re all variations on a single gadget that runs on electricity and has a motor, gearset, and lead screw. The only variable is the capacity of the motor inside. This gadget has broad applicability, finding use in many sectors. Some companies employ it in their production processes and machines, while others include it in goods like lift desks. The versatility of electric linear actuators makes them suitable for various uses.
