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 […]
Thomson online product sizing and selection tool for linear-motion systems
Thomson Industries has enhanced its Linear MOTIONEERING product -sizing and selection tool for linear motion systems. The tool reduces time for component selection from hours to less than 15 minutes. The upgraded resource also incorporates the RediMount motor mounting adapter kit — the default standard for Thomson linear motion systems and precision linear actuators. The […]
Compact voice-coil motors from Moticont with 1.0-in. diameters for myriad stroke requirements
Moticont now sells linear voice coil motors (LVCMs) in two 1-in. (25.4-mm) diameter motors. • The LVCM-025-022-01 has a stroke length of 0.375 in. (9.5 mm) a mid-stroke length of 1.30 in. (33 mm) and a high-force-to-size ratio of 16.9 oz (4.7 N) and a peak force of 53.5 oz. (14.9 N) at 10% duty […]
High-force iron-core brushless linear motor from H2W Technologies
H2W engineers have developed a compact high force brushless linear motor (BLSM-1F) that can generate 300 lb (1330 N) at a 10% duty cycle and 100 lb (444 N) at a 100% duty cycle, and, when used with a matching magnet track (BLST-FSX). The mass of the coil assembly is 19 lb (9 kg) which […]
New SMAC LBL25 linear actuators — fast, cost-competitive, and stackable
SMAC Moving Coil Actuators now sells LBL series linear actuators — price competitive with ball screw and high-cycle-rate air cylinders thanks to a simple no-milling plate design. The LBL design features flat printed coil and single-piece, screw down magnets. It’s equipped with SMAC proprietary encoder and gives more than 100 million cycle expected life. Starting […]
Choosing the right stage actuation for dynamic-metrology applications
When measurements are made to discrete product on the fly, it’s key that the motion system minimize error and correct for the rest. Brian Handerhan | Business development manager • Life sciences Patrick Lehr | Product manager • Precision mechanics Electromechanical & Drives Division • Parker Hannifin Corp. Dynamic metrology is the collection of data […]
SUPERWURM worm farm uses motion components from igus
One automated worm farm in Germany to breed and grow worms includes machines to continuously lift, transport, release, stack, drill, and spray giant red worms called dendrobena. Duren-based SUPERWURM uses robots and automated guided vehicles (AGVs) until the worms are ready for sale to fishermen, as food for animals, and as natural fertilizer for gardens […]
Festo introduces compact electric actuators ELGC and EGSC at IMTS 2018
Festo showcases at IMTS 2018, McCormick Place, Chicago, September 10-15, the new low-cost linear axes ELGC and mini slide EGSC. These new electric actuators offer an optimal ratio between installation space and working space. They feature a common system approach and platform architecture as well as space saving adapter-free connectors. The Festo IMTS Booth is in […]
THK to show low-inertia ballscrew-spline BNS-V during IMTS
In two weeks, IMTS visitors will be able to see THK’s ballscrew-spline BNS-V at booth #134514. Featuring an exceptionally compact and lightweight structure, the low-inertia BNS-V enables quick starts and stops during high-speed operation. The BNS-V is a stroke-rotary unit with ball screw grooves and a ball spline groove that cross one another on a […]
What’s the difference between serial kinematics and parallel kinematics in multi-axis motion design?
Today’s positioning tables and stages include hardware and software that’s more customized than ever to satisfy specific output requirements. That’s made for motion designs that move accurately through even complicated multi-axis commands. Precision feedback is key to such functionality — often taking the form of optical or (electronics-augmented) magnetic encoders for nanometer-scale resolution and repeatability […]
