Servo drives are electronic devices that control the precise motion of motors in automated systems, and they have become one of the most influential technologies behind today’s industrial transformation. Their rise reflects a broader shift toward flexible, intelligent, energy-efficient production. Demand for advanced motion control is accelerating fast, with global industrial automation projected to surpass 400 billion dollars within a few years. That growth is fueled by factories seeking accuracy, repeatability, speed, and the kind of reliability required for round-the-clock manufacturing.
Humanoids and cobots are rapidly serving the needs of the warehouse, logistics, material handling and packaging sectors allowing skilled workers to turn their attention to more pressing matters on the shop floor. According to MasterControl (matercontrol.com) digital transformation is revolutionizing life sciences manufacturing, driving key trends in the pharmaceutical and medical device industries.

This paper examines the selection process, operation, maintenance practices, and state of a Sumitomo gearbox after over 24 years of operation. It is demonstrated that a quality product and careful consideration of all these factors are essential for a longer service life of the gearbox. Detailed information is provided on the operation of the gearbox, as well as the maintenance practices that should be taken to ensure its longevity. Finally, the paper examines the state of the gearbox after over two decades of use and how all these factors result in lowering carbon emissions.
The call came into Atlanta Gear Works like any other—a vertical mill drive used for a crusher application in cement needed a gearbox upgrade. The difference this time was the sheer size and scope of the gearbox in question. Similarly-sized gearbox rebuilds could take a month or more to complete, but Atlanta Gear Works had 14 days to complete this rebuild—counting weekends—with a tight schedule leaving no room for error.
Greetings 2026! As expected, EV demand has waned following some deregulation and tax credits being dropped as of September 2025. For us industry folks, this is simply reality catching up with the narrative. On the plus side, 2025 was a very good year for global vehicle sales–the best since 2019 (Ref. 1). A good economy can forgive many blunders. As gearbox designers, our work continues as our EV offerings are likely a permanent part of our product lineup, even if at a reduced volume.
Closed Loop control systems can handle a wide range of motions with a wide range of loads if the control system and mechanics 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 rather how to also get the desired performance.
How does a ball screw work differently than a lead screw. Under what circumstances would a ball screw be better for your application than a lead screw. What issues should be considered when selecting a ball screw assembly.
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.
Since 1905, The Hilliard Corporation has turned innovation into a tradition. From a single clutch to a global portfolio of motion control, braking, and filtration solutions, our journey has been defined by engineering expertise, quality, and excellence.
