- TRAMI NEDO Grant advances compact high-speed e-axle research.
- Industry collaboration targets vibration and thermal engineering breakthroughs.
A research initiative led by Transmission Research Association for Mobility Innovation (TRAMI), a consortium comprising nine automakers and other organizations in Japan, has been selected to receive funding from New Energy and Industrial Technology Development Organization (NEDO). The five-year grant, beginning in fiscal year 2026, supports the development of compact, high-speed electric powertrains with a focus on next-generation drive units capable of delivering improved performance while reducing overall package size.
Project Targets Compact High-Speed E-Axle Technology
The primary objective of the program is to establish technologies for compact electric drive units, commonly known as e-axles, that incorporate electric motors capable of operating at speeds exceeding 50,000 revolutions per minute. Reaching this performance level presents significant engineering challenges, particularly in maintaining system stability, efficiency, durability, and reliability under extremely high rotational speeds while preserving compact packaging suitable for future electric vehicles.
Major Technical Challenges Identified
The project recognizes vibration control and thermal management as the most critical technical barriers to achieving reliable ultra-high-speed motor operation. Addressing these issues is essential to ensure long-term durability, operational efficiency, and safe performance. To accelerate technological progress, TRAMI intends to strengthen collaboration with companies and universities, combining industrial expertise with academic research to develop practical engineering solutions for these complex challenges.
Research Themes and Development Roadmap
To organize the development effort, TRAMI has divided the project into 32 individual research themes, each supported by a dedicated roadmap extending through fiscal year 2030. Alongside component and system development, the initiative will focus on creating advanced simulation models and establishing new measurement and analytical technologies. These capabilities are expected to improve engineering accuracy, support validation activities, and contribute to the successful realization of next-generation compact electric powertrains.
