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 […]
Dunkermotoren launches compact linear motor with double peak force
With the SA/SC 38 series, Dunkermotoren presents a new modular concept for tubular linear direct drives. The highly dynamic three-phase linear motors deliver up to 3,690 N and accelerate at over 200 m/sec2. The modular design is currently available as actuator version SA (with maintenance-free plain bearing system) and component version SC (for modules). If […]
ANCA Motion expands high-performance tubular linear motor line
The LinX M-series linear motor features an integrated position sensor with 10 um of resolution, eliminating the need for an external encoder, simplifying system design and reducing overall cost. Modular design of the heatsink and end-caps enables flexibility in system integration. The motor produces a continuous force range of 90 to 160 N and a […]
What is a direct drive motor?
A direct drive motor is any motor — rotary or linear — in which the load is connected directly to the motor, without mechanical transmission elements such as gearboxes or belt and pulley systems. In other words, the motor directly drives the load. Direct drive rotary motors Rotary direct drive motors are often referred to […]
Low-profile linear stepper motor stage from H2W Technologies
The LSS-016-04-006-01A-ME is one of a revolutionary new series of low-profile linear stepper motor positioning stages that integrates an absolute linear encoder and a single-axis linear stepper motor stage. This enables the linear stepper motor stage to operate as a 2-phase brushless linear motor when coupled with motion control electronics provided by H2W Technologies (H2W). […]

Unique to ANCA Motion is the LinX M-series linear motor which is housed within a slim body, is highly energy efficient, and delivers precision CNC applications or high-speed automation systems every time. An early adopter to new technology, ANCA […]
Compact Linear Induction Motor from H2W Technologies
H2W engineers have developed a compact Linear Induction Motor (LMAA-04-01) that can generate 10.6 lbs (47 N) of force at a 15 percent duty cycle. Operating at 208 VAC 3-phase 60 Hz, the synchronous velocity of this LIM is 160 in/sec (4 m/s). The LMAA-04-01 linear induction motor was designed for high speed operation; however, […]
When is resolution important for linear systems?
Accuracy and repeatability are standard specifications that describe how a linear motion system behaves along its travel and how closely it reaches the intended position. Resolution, on the other hand, is less often included in performance data for linear motion systems, but it can be equally important as accuracy and repeatability in some applications. In […]
Linear motion designs see wider adoption of linear direct drives
Direct drives are a motion-control technology projected to see high rates of adoption in coming years, according to market research by the ARC Advisory Group. That’s due in part to an array of industries driving for higher throughput and more accurate processes. According to Brian Scott, applications engineer at Nippon Pulse America Inc., linear shaft […]
Profitable design of linear motion: Choosing between DIY or turnkey builds
Engineers building linear motion systems can use ground-up DIY approaches or purchase complete turnkey solutions. Here we explain where each tactic is most profitable. By John Brokaw and Kent Martins | Valin Corp. How should designers pick between building linear-motion designs in-house or purchasing pre-engineered assemblies? What is there to consider when determining the best […]
