Performance-Driven Design of Multi-Stage Gear Transmissions for E-Drive Systems

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.

Modern Motion

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.

The Year Ahead in Robotics

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.

Optimizing Check–In to Takeoff

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.

The Autonomy Influence

Leaders from across the construction and heavy equipment manufacturing industries gathered in Las Vegas recently for ConExpo-ConAgg 2026. The show celebrated the innovation, economic impact and workforce powering the $2.2 trillion U.S. construction sector today.

Gear Drives

Hannover Messe 2023 provides the latest technologies in robotics, automation, motion control, IIoT, fluid power, e-mobility, material handling and more. 

Gears

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.

Bearings

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).

Motors

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.
