Traditional or integrated actuator designs: What is the best solution? Machine designers can choose from two different electric actuator technologies -- integrated or traditional -- to build linear motion systems that are reliable and efficient. Each technology offers performance advantages depending on the application type. There are several factors to consider; knowing how to assess the differences will help engineers meet their requirements.

Zirconia: The toughest of technical ceramics, also allows very fine features Zirconia partially stabilized with yttria (PSZ) features a self-healing effect that fights micro cracks and therefore makes this material tough against impact. The extremely fine available grain size is also recommended where fabrication of very fine features and thin edges is required to hold up well in applications that include medical, aerospace, semiconductor, instrumentation, and industrial.

Space Station uses silicon carbide ceramic bearing Insaco, working with a major pump manufacturer, helped design a specialized pump to process wastewater into usable water on the International Space Station. To overcome both the requirement for reliability during manned space flights and the poor lubricity of water, Insaco recommended and machined a special grade of silicon carbide for their ceramic bearing with dimensional tolerances of +/-.0002". The pump has run in space successfully since 2016. For your unique machining requirements using sapphire, ceramic, quartz, and glass, trust the experts at Insaco.

How slip clutches can help maximize your designs The way they see it over at Polyclutch, there aren't a whole lot of problems you can't solve with a slip clutch. Way beyond using them for overload protection, there are a surprising number of other applications for these versatile and valuable components. From increasing machine speeds and applying constant tension on wire to indexing a conveyor and automatic screw assembly, slip clutches just may provide the design leverage you've been seeking.

Direct-drive linear motors reduce operating costs and increase productivity Kollmorgen's new ICH family of Direct Drive Linear (DDL) servo motors improves overall equipment effectiveness by increasing productivity, reducing operating costs, and lowering maintenance costs through the reduction of mechanical components inherent in a direct-drive solution. When compared to conventional rotary systems, ICH linear servomotors increase throughput by up to 40% and enable the design of smaller, lighter machines with increased energy efficiency. The unique anti-cogging coil design provides smooth and quiet travel and delivers continuous forces ranging from 175N to 5341N and peak forces from 405N to 12,726N with voltage ratings up to 480 VAC.

Motors and encoders paired for antenna pointing systems The Celera Motion Infinity Series motor is a low-profile, direct-drive motor that is ultra-thin and arc-shaped. Segments of the motor can be used individually or combined to create a full circumference up to 360 degrees. The ironless motor delivers the smooth motion required for accurate positioning needed to make precise movements. Coupling the motor with the Celera Motion IncOder, a high-resolution rotary inductive position sensor, enables highly reliable position sensing.
