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.

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.

A Deep Dive into Automation, Conveyance, Sustainability and AI

Pack Expo East drew more than 7,300 attendees and 2,700 exhibitor personnel to highlight the latest advancements in automation, smart manufacturing, sustainable materials, and AI-driven solutions. The regional event provided new machinery, breakthrough materials, advanced automation, and smart manufacturing technologies transforming the industry in 2026.

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.

Gear Drives

For worm gearboxes, oils are mainly used in combination with splash lubrication. Consistent lubricants, such as greases, are used less frequently and are used, for example, in gearboxes where it is not possible or difficult to seal the housing (Ref. 1). These applications include positioning gears, but also power gears with high sealing requirements, such as in the food industry. Grease lubrication has, in comparison to oil, a negative thermal effect on the worm, resulting in higher mass temperatures (Ref. 2). However, this effect becomes less relevant in the application of positioning gears, so that the advantages of grease lubrication outweigh the disadvantages in these applications.

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.

Bearings

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. 

Motors

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.
