90% of small U.S. construction companies have safety programs, but only a third have programs to improve the ergonomics of workers’ environments. It’s too bad, because the risk of musculoskeletal disorders (MSDs) is especially high in construction workers. Plus annual wage and salary losses are estimated at $46 million for the U.S. private-construction sector. Workers […]
Electric actuators displace other motion options — including manual designs: A Motion Trends report
Today, electric actuators are easier than ever to specify and install. Value-add services from component suppliers as well as application-specific actuator product lines (especially for battery-powered designs in mobile equipment and consumer use) eliminate many integration tasks for OEMs and end users. These are trends supported in part by a movement Design World has tracked […]
New technologies and applications for linear motors: A Motion Trends report
Depending on the exact technology, typical linear motors can deliver unlimited strokes and (with feedback) accuracies to ±1 μm/100 mm. Speeds range from inches to 1,000s of inches per second. Semiconductor manufacture and assembly as well as machine-tool applications continue to account for the majority of linear-motor applications. However, increased focus on efficiency is spurring […]
Motion Trends: Stages, Cartesian robots, and tables for complete motion designs
New trends in multi-axis motion designs abound. Consider the rise of metrology reports to accompany designs — which serve as “birth certificates” in the form of well-informed simulation models and Excel spreadsheets that quantify the accuracy and capabilities of pre-engineered builds. In some cases, such reports give OEMs and end users accurate data on how […]
Parker Hannifin high-precision electromechanical solutions at Photonics West 2019
Parker’s Electromechanical and Drives Division will be exhibiting at SPIE Photonics West 2019 in San Francisco, February 5 to 7, 2019. Every year, more than 20,000 attendees come to the world’s largest photonics technologies event to learn about the latest research as well as find the latest devices and systems that use new technologies to […]
Enclosed PHD Plus Series ESU electric-belt-driven base slides
PHD Inc. now sells PHD Plus Series ESU electric-belt-driven base slides. The Series ESU Electric Belt-Driven Base Slides feature a robust, enclosed design with a high capacity rail bearing system delivering exceptional moment and load capability. Available in three sizes, with travels lengths up to 5,500 mm and speeds to 5,000 mm/s, these electric base […]
What are walking piezo motors?
Piezo motors that produce linear motion include linear ultrasonic piezo motors, linear stepper piezo motors, and piezo inertia motors. Although their construction and principles of operation are different, all three designs harness the inverse piezoelectric effect — in which a piezo material expands or contracts when electrical energy is applied — to produce linear movement in a […]
Low-profile XY open-aperture stage features 1 micron resolution, 2 micron repeatability
OES (Optimal-Engineering Systems, Inc.) has added a new, high-precision open aperture stage to its expanding line of precision XY stages. The AU200-100×100 stage is a low profile stage measuring just 80 mm (3.150 in.) high with a compact footprint (including the motors) of 348 mm x 348 mm (13.701 in. x 13.701 in.) The linear […]
Under development: Linear stroke-extending technology from Ascending Power
In a recent email exchange with London-based John Hammerbeck of Ascending Power, we learned more about a novel new linear-motion extension technology from the company. The actuator steps up a short input stroke to a long output stroke using either kinematic linkages or permanent magnets. Below is a SolidWorks animation of the linkage variation; depending […]
Motorized linear X-axis plus rotary positioning stages from OES
Optimal Engineering Systems, Inc. (OES) has released a new series of high precision X-axis stages with integral rotary positioning stages. The four X-and-theta stages in this series feature linear travels of: 15 mm (0.591 in.), 30 mm (1.181 in.), 50 mm (1.968 in.) and 75 mm (2.953 in.). The rotary table is capable of continuous […]
