When a ferromagnetic material is subjected to a mechanical stress — caused by an applied force or torque — it experiences a change in magnetic flux. This phenomenon is known as the magnetoelastic effect, also referred to as the Villari effect, for the Italian physicist who discovered it in the late 1800’s. In motion control […]

Direct-drive, high-resolution electric cylinders with integrated encoder
The SDLM-025-070-01-01 and SDLM-025-070-01-05 direct drive linear motors from Moticont, also known as electric cylinders, have built-in encoders, and feature high acceleration, high speed, high resolution, zero backlash, and zero cogging. These compact direct-drive linear motors with quiet linear plain bearings are just 1.00 in. (25.4 mm) in diameter and 2.75 in. (69.9 mm) long. […]
Standard versus custom slip rings — and inductive, capacitive, wetted mercury variations
Slip-ring variations abound — and the advanced components come in bore sizes from half an inch to many feet in diameter — for medical-imaging machines designed to service livestock, for example. But options go beyond mere scale. So how do OEMs and design engineers choose between standard and custom options … and what are other […]
Video on torque limiters: Examples of how to customize for industrial applications
In a recent video with Lee Teschler, we go over three torque limiters from Mach III — a Kentucky-based manufacturer of stock and custom brakes, clutches, and torque limiters. The manufacturer can usually deliver custom designs within two days of obtaining application requirements. Mach III also meets or beats purchase-order ship dates 98% of the time. […]
Video: Five air-engaged clutches from Mach III (a Design World overview)
In a recent video with Lee Teschler, we investigated five air-engaged clutches from Mach III. The company designs and manufactures an array of air and spring-applied friction brakes and clutches — as well as mechanical torque limiters and combination clutch-brakes for industrial applications to 5,000 ft-lb. Watch the video: First we detail a C2H2R-STH […]
What is an LVDT (linear variable differential transformer)?
A linear variable differential transformer (LVDT) is an absolute measuring device that converts linear displacement into an electrical signal through the principle of mutual induction. Its design and operation are relatively simple, providing extremely high resolution in a device suitable for a wide range of applications and environments. The main components of an LVDT are […]
What are rotary unions and how are they used in motion applications?
Rotating components are common in motion applications — robot arms, winders, spools, spindles, and rotary tables are just a few examples. And while creating rotary motion is easy, when air or liquids need to be transferred from a stationary supply to a rotating component for cooling, heating, lubricating, or transmitting fluid power, the task becomes […]
Frameless brushless dc motors in hybrid solid-state LIDAR Applications
Edited by Terry Persun || Use of light detection and ranging (LiDAR) in the automotive industry is growing exponentially. The two most common variations are solid-state LiDAR and hybrid spinning LiDAR. Solid-state LiDAR are non-spinning systems. Some employ a phased array to steer the laser beam sans moving parts; others include a tiny mirror to steer […]
Explosion proof stackable multi-turn encoder from Sensata
Sensata Technologies debuts the first explosion proof stackable multi-turn encoder for use in oil and gas applications. The new encoder, BEI Sensors’ model MAAX, is ATEX and IECEx certified to operate in explosive environments and features a Profibus output in a unique, stackable package. CANopen and SSI outputs are also available. The MAAX provides up […]
GAM introduces EPR and PER right-angle bevel planetary gearboxes
GAM, a leading manufacturer of precision gear reducers, servo couplings, and linear mounting kits, announces the release of its new EPR and PER Series Right Angle Bevel Planetary Gearboxes. These new gearboxes provide all the advantages of GAM’s popular EPL and PE inline planetary gearboxes in a right-angle configuration. “The EPL inline is considered the […]
