What questions to ask when choosing an actuator or linear robots to avoid selection errors
What Precision I’m looking for (Precision and repeatability), this will help us choose which family and type of product we will have to choose the solution in, and the need to have a linear coder and a closed loop on the actual position of the system.
What orientation will the system be installed? Vertical, horizontal, angled, The forces applied to the cart will be different and the gravitational force will have to be taken into account.
What speed , and acceleration the system have to support ? The engine capacity, Drive and, support, bearing will have to withstand the forces of acceleration and deceleration of the system and be able to deliver the required performance
What Length ? Including acceleration and deceleration zone to achieve required speed
What’s the Load ? The weight and its distribution as well as the forces applied with their directions. Any loads deported from the rolling system will result in a moment of force, which the system must be able to withstand without introducing a position error. Any workload performed by the actuator, (cut, push, pull, polish) , Include the weight of the tool, servo motor, gearbox and other axes.
What is the work cycle, and durability required by the application
Other factors to consider, safety, brake for the load, other forces, motor manufacturer and model
What type of environment the product will be subjected to, temperature, debris, chemical, wash down , type of maintenance. Influences the selection of materials and type of bearing and lubrication required.
Hoping that this list of questions helps you better visualize your needs, You can contact Prosynergic to discuss your application it will be our pleasure to help you.
