When Australian steelmaker InfraBuild needed two new circuit breakers to provide backup for its main electric arc furnace, ABB had the solution—its VD4-AF vacuum circuit breaker with an innovative servomotor actuation system that delivers more than five times the operations of a standard breaker, supporting greater reliability and safety as well as lower operational costs.
Bosch Rexroth continues to expand the ctrlX platform with new capabilities and automation enhancements. The control platform ctrlX COREplus is now available with AI functions on all performance levels. In the area of motion and drives, Bosch Rexroth is presenting compact, energy-efficient, and cabinet-free drives from the ctrlX DRIVE portfolio, which cover virtually all performance ranges. These are complemented by the Motion, CNC, and Robotics software ctrlX MOTION, which is ideal solution for automating production machines and systems. PTE recently had a great conversation with Garrett Wagg, product manager, controls at Bosch Rexroth on new developments in mobile robotics.

Consider the following scenario: guided by vision sensors, a robot spots a product on a moving conveyor, determines its exact position and, in one fluid motion, picks it up and places it into a waiting assembly, carrier tray, or shipping container. What human operators once found tiring—or at least tedious, the robot performs flawlessly, hour after hour, even long after its flesh-and-blood coworkers have gone home for the evening.

The load limit diagram of a motor spindle serves to graphically represent the permissible operating range as a function of parameters such as rotational speed. It enables a quick assessment of the conditions under which the spindle can be operated safely and reliably without exceeding mechanical, thermal or dynamic limits. Such a diagram is a key tool for the design, selection and evaluation of spindle systems in mechanical engineering particularly in the field of machining where high demands are placed on precision, performance and service life.

Despite a lukewarm sustainability agenda here in the United States, global bearing manufacturers continue to be motivated by eco-friendly technologies, environmental awareness and energy efficiency regulations. Material innovation is one of the key strategies to reduce environmental impact moving forward. Concerns include energy consumption in manufacturing, waste generation, emissions from lubricants and raw material extraction. The end goal is to provide longer-lasting components with less waste.

Half a million global visitors visit Aiguille du Midi as an access point for skiing in the winter and hiking, rock climbing and paragliding in the spring, summer, and autumn seasons. The mountain—part of the French Alps—boasts the current title of employing “the world’s highest vertical ascent cable car.” This unique transportation takes passengers from 3,396 to 12,605 ft. above the clouds. The planetary gearboxes needed for the cable car operation are provided by CMD Gears.
It’s common to hear “surface roughness” described as a number that can be measured on a gage. But describing surface texture with a number is a lot like describing a concert in decibels: loudness is just part of the story. A rock band, an orchestra, and a chainsaw can all produce 100 decibels, but the full picture is much more complex and interesting.
For over two decades, our Montreal-based engineering simulation consultancy has provided advanced solutions to a diverse range of industries. Our expertise has facilitated the resolution of complex engineering challenges, leveraging the latest technologies in computational fluid dynamics (CFD) and heat transfer analysis. Among our recent projects, one particularly notable case involved a company specializing in converting combustion engine vehicles to electric vehicles.
Closed-loop control systems can handle a wide range of motions with a wide range of loads if the control system and the mechanics of the system are properly designed for the task. A couple of the more difficult combinations to design for are high inertial mismatches and backlash with hard gearing. The question is not just how to make the system stable but also how to get the desired performance.
The drive system choice is dependent on key motion features of your application. Lead screws offer self-locking capabilities, while ball screws require brakes to prevent back-driving. The choice between them hinges on efficiency, cost, precision, and speed, with the screw drives themselves paired with a linear guide for optimal performance.
Bellows couplings are commonly used in applications requiring precise rotation, high speeds, and dynamic motion transmission. With zero backlash and a high level of torsional stiffness, they offer clear performance advantages in many servo-driven systems.
The Simplicity self-lubricating linear plain bearings are built to last, and they will often out-perform and last longer than a traditional linear ball bearing. Called the “little red bearing” by loyal customers, they have been a popular replacement for failing ball bearings. Simplicity plain bearings will not catastrophically fail.
The difference between a smooth-running drive and constant headaches? The right timing belt and pulley plus a whole lot more. Discover what works, what doesn’t, and put your design skills to the test—engineer your best system yet!

ABB has signed an agreement with Fervo Energy, a Texas-based leader in enhanced geothermal systems, to supply advanced motor control solutions for the Cape Station geothermal project in Utah. Scheduled to start delivering reliable, carbon-free power to the grid in 2026, Cape Station is expected to become the world’s largest next-generation geothermal development by installed capacity and represents a major step forward in sustainable energy generation in the United States.
Nord Drivesystems utilizes data-based simulations for the development of components and drive solutions and recently, to create digital twins for system development. This technology allows engineers to verify early in the planning process whether the drive concept is suitable for the system, significantly reducing project timeline and achieving greater efficiency and availability.
