Specifying Actuators for Cleanroom Environments

Selecting the right actuator for use in any manufacturing operation involves a host of application-specific variables, including aspects such as the required stroke length, load capacity, acceleration, maximum speed, and positioning repeatability. Add a cleanroom specification to the list and the choice of available options becomes significantly smaller. Consider these questions to help make the best choice for your cleanroom application, whether it’s for the medical device, pharmaceutical, biotechnology, or semiconductor manufacturing industry.

NASA's Hot 100 Technologies: Mechanical & Fluid Systems

Spring Joint Package with Overstrain Sensor This flexible joint provides two degrees of freedom and a tremendous amount of compliance. The overstrain sensor joint has a passive and restoring force that allows the joint to return to a default position, and is also proportional to the amount of lateral deflection the spring has undergone; this allows the OS sensor joint to be used in many of the under-constrained situations that cause universal joints to lock up.

Selecting Miniature Motors for your Medical Devices

The creation of small, portable infusion pumps opened a new chapter in medical care. A patient can receive carefully metered and timed doses of medicine, without requiring a visit to the medical practitioner, allowing life to be less restrictive. Ambulatory pumps have been developed to deliver insulin, nutritive supplements and anticancer drugs.

Moving Magnet Voice Coil Actuators Offer Controllable Movement for High-Duty-Cycle Applications

There are two types of voice coil actuators: moving coil and moving magnet. The materials of construction are similar, since they both use rare earth magnets, steel, copper wire, and basic insulation materials. There is a tendency to want to say one type is better suited for certain applications; however, there are many different sizes and shapes of voice coil actuators, making it difficult to make blanket statements about which type of actuator works better, and where.

Specifying Actuators for Heavy-Duty Packaging Applications

The task of selecting, sizing and applying linear actuators involves many variables, from stroke length and duty cycle to precision and accuracy requirements. Ultimately, matching the right actuator to the intended application requires a close look at all of the specifications involved and then working within the project’s performance, time and budget constraints. Certain manufacturing operations are more rigorous than others, with end-of-line packaging applications among the most demanding when it comes to linear actuation. Activities such as palletizing, case packing, cartoning and lane diverting require strong and reliable motion components. What does a design engineer or system integrator need to know when selecting actuators for these heavy-duty packaging operations? Here we take a detailed look at some of the most important aspects to consider.
