ABB Upgrades NASA Wind Tunnel With Powerful Motor Drive

This article examines how ABB modernized NASA's wind tunnel drive for aircraft testing, extending its life by 10+ years. The world’s largest cryogenic wind tunnel at NASA’s National Transonic Facility in Langley, Virginia, began operating in 1984. However, in 2021, NASA’s engineers determined that the tunnel’s medium voltage drive, supplied by ABB in 1997, was nearing the end of its life and in need of an upgrade.

At installation, ABB’s 101-megawatt drive was the most powerful of its kind. However, with the drive nearing 30 years of service, NASA ordered an upgrade project under ABB’s Motion OneCare service agreement. This agreement offers a tailored approach to maintenance, allowing organizations like NASA to bundle services for their ABB motors, generators, and drives.

BYD vs. Tesla: Who Wins the EV Battery Battle?

In this article, we looked at how researchers at RWTH Aachen University in Germany have provided unprecedented insights into the battery technologies powering the world's two leading electric vehicle manufacturers, BYD and Tesla.

The detailed examination reveals how BYD's lithium iron phosphate (LFP) Blade batteries and Tesla's nickel manganese cobalt (NMC) cells represent fundamentally different approaches to solving the challenge of energy storage for EVs. Each design reflects distinct priorities and engineering philosophies that shape the performance, safety, and cost profiles of these competing technologies

Top Industry Articles

AI-Powered Digital Twins for a Resilient Energy Infrastructure and Wildfire Prevention

There’s no doubt that AI was the key technology trend of 2025. This article covered how Siemens Energy and NVIDIA are working together on building geospatially accurate 3D AI models of our electrical grid to optimize utility operations, maintenance, and response plans for emergencies and natural disasters.

There’s perhaps no more vivid example of the need for technology than the horrific wildfires in Los Angeles in January 2025. The two companies plan to build a new AI Lab that will use NVIDIA AI expertise as well as accelerated computing to process geospatial data that will be used to train and fine-tune domain-specific AI models.

Top New Industry Products Article

GaN Motor Inverter Packs Power in Small Spaces

It’s perhaps not a huge surprise that this New Industry Product article was this year’s top reader favorite. It involved a key technology of this era: Gallium Nitride (GaN). As a reference design, it’s a product that engineers can sit down and start working with right away. And it’s aimed at designs like robots, and how doesn’t love robots!

EPC’s EPC91120 reference design provides a BLDC motor inverter, built around the company’s EPC23102 eGaN power stage IC. It bundles power delivery, sensing, and motion control into a compact, 32-mm circle that fits directly inside a joint motor. Think of it as giving each joint its own “nervous system” instead of relying on bulky, centralized electronics.

Principles of High-Voltage Transmission

For years, some of EEPower’s most popular Technical Articles are ones that get right down to the basics. This reader's favorite article of 2025 does just that.

The article explores the fundamental principles of high-voltage power transmission. It focuses on its advantages for efficient long-distance energy delivery, and examines the impact of voltage levels on current, power losses, conductor sizing, insulation requirements, and the environment.

In short, the story examines the fundamental principles behind high-voltage transmission and how it plays a pivotal role in modern electrical infrastructure.
