Captive shaft electric cylinders are now available for Lexium MDrive (LMD) integrated motor products. Quiet, clean and compact, these LMD products integrate motor, controls, and electric cylinder to deliver linear motion. And, unlike pneumatics, there is no need for compressed air, eliminating maintenance and noise issues. Lexium MDrive products integrate 1.8° 2-phase stepper motors with […]

When do tubular linear motors outperform traditional iron core and ironless designs?
In a recent post, we looked at traditional iron core and ironless linear motors, both of which have a flat-type construction. But another type of linear motor, often referred to as a “tubular linear motor,” is also gaining traction in industrial applications. This is especially true in the packaging and medical industries, where tubular linear motors […]
Keeping the elements at bay
Keep these five key factors in mind when selecting mechanical components for harsh environments. Chad Carlberg Product Line Manager for Industrial Actuators Thomson Linear As electromechanical actuators and other mechanical motion components expand in capability for heavy duty applications, so does their capability to resist harsh conditions. Extreme temperatures, high particulate levels, chemical exposure, high-pressure […]
3 things to consider when choosing a linear servo motor
Direct drive linear servo motors have seen a measurable increase in adoption over the past several years, thanks in part to end users’ demands for higher throughput and better precision. And although linear motors are most often recognized for their ability to provide a combination of high speeds, long strokes, and excellent positioning accuracy that […]
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. […]

How to specify motion components for cleanroom environments: Part 2
In this two-part article, we cover the products, materials, and features that designers and engineers should specify when choosing motion components for cleanroom environments. In part 1, we looked at how to reduce particle generation due to friction between moving components. In this second part, we’ll look at another source of contamination — outgassing — […]
How to specify motion components for cleanroom environments: Part 1
In this two-part article, we cover the products, materials, and features that designers and engineers should specify when choosing motion components for cleanroom environments. In part 1, we look at how to reduce particle generation due to friction between moving components. Designers of automation systems are tasked with many competing demands, such as balancing cost and performance, […]
How does stiffness affect piezo output force and displacement?
Piezo actuators operate on the inverse piezoelectric effect: when voltage is applied, the actuator contracts or expands. But when the actuator is blocked from moving (by a load applied in the direction of travel), it generates a force. This relationship between displacement and force in piezo materials is an inverse relationship. In other words, the […]
How do rotary voice coil actuators work?
Most linear motion devices have a rotary equivalent, and voice coil actuators are no exception. While the versions depicted in most product images and videos are linear, rotary voice coil actuators fill a need for smooth, arc-shaped motion and torque production with fast response times. But unlike the design relationship between rotary and linear motors, […]
