Contributed FAQ courtesy H2W Technologies || Linear-induction motors work in applications that require rapid movement of large payloads. Linear-induction motors can output speeds to 1,800 in. per second (45 m/sec) or more … … and accelerations from 3 to 4 g. Standard LIMs can produce forces in the range of 720 lb (3,200 N) at a 3% duty cycle. […]

How do linear induction motors work?
Contributed FAQ courtesy H2W Technologies || Think of linear induction motors (LIMs) as rotary motors that have been cut and unrolled to generate linear instead of rotary motion. Linear induction motors are comprised of two parts, the primary and secondary, which interact with one another only when power is applied. Either the primary or the […]
Compact actuators help save some dough
Edited by Mike Santora In machines for industrially manufactured bakery products, product changes must be flexible, precise and repeatable. This requires precision with numerous set-up and adjustment options. Siko integrated fieldbus positioning drives into the new “Soft Star CTi” dough dividing and molding machine, which combines the motor, transmission, absolute measuring system, control and power […]
8 commonly misused engineering terms explained
While much of the terminology in engineering and automation is standardized, some words are still widely misused, especially when different terms apply to similar principles. And the fact that a term may have different meanings in different disciplines (i.e. physics vs. engineering) makes it difficult to know which word is the most accurate and appropriate for a […]
Option for fine-stroke adjustment improves linear-drive reversal point accuracy
Amacoil-Uhing Model RG linear drives now feature an option for fine adjustment of maximum travel distance. On the standard Amacoil-Uhing drive assembly, the end stops limiting travel distance are set by hand. With the new option, the end stops ride on threaded rods with control knobs on both ends. Turning the rods moves the end […]
Actuators with haptic feedback: Ultra-thin PiezoHapt actuator with low driving voltage
TDK now sells a new haptic component — a new ultra-thin PiezoHapt actuator featuring a short response time of just 4 msec. PiezoHapt has a unimorph design consisting of a multilayer piezo element bonded to one side of a vibration plate. With a thickness of a mere 0.35 mm the new haptic actuator is much thinner than conventional eccentric […]

Rexroth Open Mechatronics Demo at ATX West 2017
Bosch Bosch Rexroth will showcase an Open Mechatronics demonstration at this year’s ATX West trade show. The demonstration utilizes Rexroth’s Open Core Engineering solution on an L25 controller in conjunction with an Excel spreadsheet to program the motion. The motion design demonstrates the position of a two-axis Cartesian system with a CKR X axis, an […]
ETEL expands linear motor line
As engineers expand their range of machines to a point where a larger payload is required, an upgrade of their linear motors may be necessary. So, to make their design process easier, ETEL has added extra ironcore linear motor lengths to each of their different widths. These new lengths are compatible with existing 50, 70, […]
