In a belt drive system, the motor, belts, pulleys, and sheaves all receive engineering attention during design and specification. The motor base typically does not. It is the overlooked component, selected on frame size and bolt pattern, specified late in the process, and treated as a passive structural element, something that holds the motor in place and sets belt tension at installation.
Drones are tasked with providing state-of-the-art autonomous capabilities, unique movements, automated inspection, urban delivery solutions and advanced military operations. They upgrade agricultural farming technology, provide safety and logistic solutions and report key disaster and engineering mapping. PT components such as motors, controllers, and sensors are an integral part of their core structure.

UGRacing is the University of Glasgow’s Formula Student team. Since its inception in 2005, the team has been working to compete at Formula Student UK (FSUK). Over the last decade, the team has grown to over 150 members across ten disciplines. With a strong focus on knowledge transfer and iterative design, the team has worked year after year to develop new technologies and a more refined package. In 2022, the team saw a culmination of all their hard work when they placed first overall in FSUK with their final internal combustion vehicle. The following switch to an electric powertrain brought new challenges. Through the constraint of a new powertrain architecture, the team has explored and innovated drivetrain concepts which, in future years, will improve vehicle performance.
The digital transformation is fundamentally changing the industry, and digital twins play a central role. They enable real-time monitoring of physical systems, simulation of their behavior, and informed decision-making. A dissertation from the TU Darmstadt Institute for Product Development and Machine Elements (pmd) shows how the FVA-Workbench gearbox design software can be implemented as a platform for creating digital twins of industrial gearboxes. The results demonstrate how the combination of detailed modeling, continuous real-time calculations, and engaging dashboard visualization offers an efficient and user-friendly solution for the development of digital twins.
We have all seen the Q4 2025 headlines around electric vehicle (EV) sales and they were not good. Ford recorded a $19.5B loss in EV pullbacks (Ref. 1). General Motors posted $6B in EV debt (Ref. 2). Stellantis took a $26B hit which was compounded by underperforming EV sales and recovery from the previous CEO’s disastrous cost-cutting strategy (Ref. 3). Also, notably, was the laundry list of not-long-ago hailed startups that have went bankrupt, often leaving investors, suppliers and employees holding the bag: Bollinger, Canoo, Nikola, ELMS, Lordstown, Fisker, Arrival, Proterra, Volta just to name a few. Many more are on the brink along with dozens of startup suppliers that enticed investors with untold wealth to be gained in the automotive revolution 2.0 (Ref. 6,13,14).
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.
Napoleon Engineering Services’ “Brief Guide to Bearing Source Qualification” is the result of nearly 30 years of real-world experience guiding OEMs through the qualification process and is based on NES’ background in the aerospace and industrial sectors and its own desire to empower customers with the technical information needed to make informed supplier decisions.
Push beyond traditional 60Hz limits with advanced VFD strategies like field weakening and motor supercharging. Expand speed range, improve system stability, reduce cooling requirements, and even downsize motors. Discover how to unlock more performance and efficiency from your gearmotor design.
Spiroid Gearing delivers precision gearing for advanced mechanical systems, engineered to handle extreme torque and complex motion requirements. With unique right-angle gear solutions, our technology enhances efficiency, reliability, and design flexibility - empowering engineers to push boundaries in aerospace, defense, robotics, and industrial applications where performance and durability are non-negotiable.
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 robust performance of the robot welder at Centerline Brackets led the Florida-based manufacturer to an exceptionally rapid return on investment, achieved in less than three months. The Universal Robots' collaborative robot dramatically cut production time and addressed labor shortages while ensuring consistent weld quality for heavy-duty brackets.
