1 Realizing the High Precision Load Handling Benefits of Rodless Electromechanical Actuators (February 2019)

Electromechanical rodless linear actuators can offer better load handling in smaller spaces than rod-style actuators, but realizing those benefits requires careful attention at the specification level. Whether you are replacing a failed actuator, looking for better performance or building a new application from the ground up, success depends on how precisely you specify application requirements.

3 Leveraging Stepper Motor Linear Actuator Configurability (December 2020)

When designers and integrators need simple, flexible and compact linear actuation, they often turn to stepper motor linear actuators (SMLAs). The high configurability of SMLAs is among their greatest virtues, but sorting through myriad configuration options to tailor the optimal solution for a particular application can be a challenge for even the most seasoned motion engineer.

4 Reduce Your Linear Motion Assemblies to a Single Component with Motorized Lead Screw Actuators (December 2019)

9 Linear Motors (October 2016)

When the need arises for linear motion or positioning, there are many choices. One can use an Acme screw, ball screw, rack & pinion, or belts. The cost of a linear motor solution is generally greater than a mechanical linear product, but when one needs highly accurate, repeatable, high-speed motion, then the answer may be a linear motor.

25 Improvement of the Noise and Vibration Behavior of an Electromechanical Brake Booster - an Integral Approach (March 2020)

The automotive world faces a tremendous change. Autonomous driving and electrification are two big topics in this context that are pushing this change. The demand for higher comfort, higher safety and tightened environmental requirements drive as well the technological change from former mechanical actuations to electro-mechanical systems in new vehicles. This can be observed especially for braking and steering systems.

26 Development of an Actuator for Ambient to Cryo Application (December 2010)

During the qualification campaign of the NIRSpec (near-infrared spectrometer) instrument mechanism, the actuator could not achieve the expected lifetime that had been extended during the development phase. The initial design could not be adapted to the requested number of revolutions during that phase. Consequently the actuator needed to be modified so that the function of the mechanism would not be endangered or, by extension, the overall function of the NIRSpec instrument. The modification included a change of the overall actuator design—internal dimensions, tolerances, materials, lubrication and assembly process—while keeping the interface to the mechanism, mass and function.
