Most linear motion devices have a rotary equivalent, and voice coil actuators are no exception. While the versions depicted in most product images and videos are linear, rotary voice coil actuators fill a need for smooth, arc-shaped motion and torque production with fast response times. But unlike the design relationship between rotary and linear motors, […]
Electric motors: Trends in stepper, battery-powered, and integrated motion designs
From induction motors in electric vehicles to tiny coreless dc motors in drug-delivery equipment, electric motors continue to proliferate. Last year we saw consumer products, implantable medical devices, and automation of previously manual tasks spur the most innovation in motor design and use. This year those trends continue — and now we see increased use […]
Engineered materials and upfront design work (are leading trends for mechanical components)
Seals, chains, cable carriers, springs, retaining rings, and general power-transmission (PT) components continue to see new materials at critical surfaces; proliferation of application-specific versions (especially for compression and wave springs); and increasingly practical online purchasing for both off-the-shelf components and customized orders. Here we explore some of these trends. Online B2B ordering of very specific […]
SERAPID supplies Meridian Lift for XXIII Olympic Winter games opening ceremony
The SERAPID solution has once again been chosen to provide dynamic stage action for the opening ceremony of the 2018 Olympic Winter Games in Pyeongchang, South Korea. SERAPID had previously provided an extensive stage lift system for the 2008 Summer Games in Beijing, China. The opening ceremony took place in the Pyeongchang Olympic main stadium, […]

Video illustrates smart linear actuator benefits for automation applications
Thomson Industries Inc. has released an educational video (below) that summarizes the benefits of smart actuators, which feature integrated electronics. The five-minute video explores how smart electromechanical actuators are meeting demands for greater connectivity, application flexibility and cost efficiency, and illustrates their use in factories, on- and off-highway vehicles, and structural automation. In discussing the […]
Belt drive axes can reduce automation costs
Mechanical engineers often need a basic, space-saving linear guide when designing technology that performs simple tasks, such as vending machines. Since such technology does not handle high loads, high speeds or high positioning accuracy, intricate linear guides are not necessary. However, most solutions on the market are very advanced, leaving manufacturers forced to either pay […]

Electromechanical cylinder is powerful, features hygienic design
With the second generation EMC electromechanical cylinder, Rexroth expands the possibilities for utilizing these compact drive units. With their hygienic design and IP65 protection class, they are now suitable for applications with frequent cleaning cycles in the food industry. The new size EMC100-XC-2 increases the power density for feeding forces of up to 56 kN, […]
Which piezo motor types experience wear?
Piezo elements are used in a variety of configurations to provide rotary or linear motion in applications that require short strokes and fast response times. Piezo elements that are used to produce motion through the inverse piezoelectric effect are known as piezo actuators. These devices provide very small displacements with extremely high resolution. When one […]
