With near-constant updates on the number of COVID-19 cases confirmed globally, you’ve probably heard about various methods to screen for the virus that causes the disease. Although several well-proven methods already exist to detect the virus, laboratories around the world are experimenting with new tests and methods to provide faster and even more reliable screening. […]

Linear actuators for medical ventilators and respirators available in OEM quantities
During the COVID-19 pandemic engineers and designers of medical devices are working 24/7 to design and manufacture critically needed life support and testing equipment. Moticont has a proud history of supplying precise, reliable voice coil linear actuators used in medical ventilators and respirators and will be especially quick to respond to the need for actuators […]
AutomationDirect adds linear position potentiometers and accessories
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 […]
Out with the oil, in with the screw
A new generation of electromechanical actuators is replacing hydraulic cylinders in demanding applications. Increasingly, that choice is being driven as much by cost advantages as by performance. Tarek Bugaighis Ewellix Traditionally, when engineers wanted to produce large forces or move heavy loads their first choice would be hydraulic actuation. Today, however, hydraulic systems have a […]
Linear motion in medical applications: Lead screw driven syringe pumps
When we think of syringes, we typically think about the single-use type that doctors and nurses use to administer vaccines or individual doses of medication. But some conditions necessitate frequent or constant doses of critical medication, making it undesirable or even unfeasible to administer via single-use syringes. And in other cases, medications that would normally […]
High load capacity actuator from NB Corporation
This compact single axis actuator from NB Corporation features a unique “U” shaped integrated slide guide and ball screw. The BG actuator’s highly rigid structure may be one-end supported. The 4 ball circuits contained in its slide block deliver high load capacity, accuracy and rigidity. The product catalog supplies all dimensions, drawings and ratings necessary […]
Linear motion in medical applications: Voice coil actuators in ventilators
More and more, medical device manufacturers are replacing traditional components with smaller, lighter-weight options that have sufficient life and reliability for “life-critical” applications. One such example comes from manufacturers of ventilators, who are using voice coil actuators to control the valves that deliver air to a patient who’s unable to breathe on their own. Ventilators are […]
New DR Series compact electric cylinders from Oriental Motor
Oriental Motor now sells DR Series compact electric cylinders based on 28-mm AZ Series or PKP Series stepper motors. The DR Series is available with an AZ Series or 2-phase PKP Series base motor. The DR Series is a linear motion actuator that incorporates a precision ball screw into a stepper motor … saving space, […]
New tools, services aid ball screw selection and design
Ball screw performance continues to improve, thanks to advancements in manufacturing methods and materials. Newer generations of ball screws have higher load capacities, which means they’re increasingly being used for applications with higher loads as well as more challenging environmental conditions. Hence, the rise in ball-screw-driven actuators replacing traditional fluid power actuation methods in some […]
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 […]
