GEFRAN linear potentiometers and accessories are now available from AutomationDirect. Linear potentiometers are used to detect position and linear direction movement. A sliding contact moves along a linear resistive element acting as a variable resistor. The proportional change in resistance indicates the position and provides a distance measurement signal. A signal conditioner can be used […]

Linear shaft motors see increased force capabilities thanks to advances in magnets
By Paul Denman • Applications engineer and business development • Nippon Pulse America Today most linear-motion designs execute their strokes with actuators based on stepper motors or brushless dc (BLDC) servo motors. Such designs have an inherent complexity due to the fact that the motors and its gearing and encoder must essentially hang off the […]
New generation of linear motor stages from Yaskawa
The Drives & Motion Division of Yaskawa America, Inc. has added the Sigma Trac II series linear servo motor stages to the Sigma-7 servo family. Sigma Trac II combines a Yaskawa SGLF2 series linear motor with linear bearings, high-resolution absolute optical scale, cable management, and optional bellows to create a turnkey linear stage. Leveraging the […]
Transport and positioning perfected: Flexible Transport System FTS from Rexroth
With its linear motor-driven transfer system, Bosch Rexroth serves a wide variety of work specifications. For the highly dynamic transport and exact positioning of materials and workpieces, linear motor-driven transfer systems are an ideal choice. Bosch Rexroth is enriching this market segment with innovative solutions that can meet the specific requirements of series and special […]
Which type of linear actuator is best for thrust forces?
When an application requires pure thrust forces, the best type of linear actuator is often a rod-style actuator. Also referred to as “thrust actuators” and (when a motor is integrated) “electric actuators,” these electromechanical devices excel at providing axial, or thrust, forces for pushing, pulling, or holding loads. Although their function is straightforward, thrust actuators […]
LinX tubular linear motor offers 10 micron resolution and peak force up to 1200 N
ANCA Motion’s new tubular linear motor LinX M Series offers 10 μm resolution at a peak force range of up to 1,200N Available in Q2 2019, the latest addition to the LinX range continues to support demanding automation applications while increasing efficiency in a compact footprint. The LinX M-series linear motor features an integrated position […]
What are linear induction motors?
An induction motor is one in which the current in the rotor is induced by the electromagnetic field in the stator, eliminating the use of magnets. A linear induction motor is a type of linear motor based on a rotary AC induction motor. Like permanent magnet linear motors (commonly designated as ironless and iron core types) […]
Electric actuators displace other motion options — including manual designs: A Motion Trends report
Today, electric actuators are easier than ever to specify and install. Value-add services from component suppliers as well as application-specific actuator product lines (especially for battery-powered designs in mobile equipment and consumer use) eliminate many integration tasks for OEMs and end users. These are trends supported in part by a movement Design World has tracked […]
New technologies and applications for linear motors: A Motion Trends report
Depending on the exact technology, typical linear motors can deliver unlimited strokes and (with feedback) accuracies to ±1 μm/100 mm. Speeds range from inches to 1,000s of inches per second. Semiconductor manufacture and assembly as well as machine-tool applications continue to account for the majority of linear-motor applications. However, increased focus on efficiency is spurring […]
Moticont high-resolution electric cylinders include integrated encoder
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. Protected […]
