The electrification process involving urban mobility vehicles is pushing research into developing efficient and durable transmissions. The transmission system has the crucial role of transforming the electrical energy produced by the electric machine into mechanical power, which is subsequently delivered to the wheels through a gear reduction system.
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.

As someone who has spent more than four decades involved in the robotics industry, I can say unequivocally that this is the most exciting time ever. From a technology that was originally used predominantly by U.S. automotive companies, robotics has now spread to nearly every industry and every country around the world.

Airports where hundreds of airplanes take off and land around the clock require perfect planning and coordination—and the tailor-made drive technology to process thousands of passengers and their baggage securely, every day. The growing focus on capacity and security issues, as well as shorter ground times, are presenting major challenges for the airport industry.

Hannover Messe 2023 provides the latest technologies in robotics, automation, motion control, IIoT, fluid power, e-mobility, material handling and more.
Future electric and hybrid electric vertical takeoff and landing vehicles will require high-efficiency and lightweight electric motor-driven propulsion systems. One key to designing an optimum electric motor-driven propulsion system, is to have a method for estimating the mass and efficiency of a gearbox for different power levels, motor speeds, and propeller speeds. Understanding the trade space for gearbox mass and efficiency allows the overall optimization of the propulsion system.
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 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.
Linear Slide Guides with a tall profile linear rail resist bending under load, thus enhancing rigidity. Their angled rail surfaces prevent debris accumulation, making them ideal for contaminated environments and cleanrooms
