The Revolutionizing Electric Traction (ReET) project represents a transformative step in next-generation electric mobility by developing high-performance, magnet-free traction motor technology for electric vehicles (EVs). By eliminating reliance on permanent magnets - often associated with critical raw materials - ReET enhances supply chain resilience while advancing sustainability and technological sovereignty. The project positions Finland at the forefront of energy-efficient and resource-independent transport innovation by delivering scalable, high-efficiency traction solutions that advance technology readiness toward real-world deployment. Through integrated motor design, power electronics, lubrication optimization and system validation, ReET contributes directly to the electrification of heavy transport and the broader energy transition.
Background
The electrification of transport introduces new engineering challenges across motor design, drivetrain integration and tribological performance. While electric traction systems eliminate combustion-related emissions, they operate under significantly different mechanical and electrical conditions compared to conventional internal combustion engine drivetrains.
In EVs, efficiency requirements are more critical than ever, as viscous losses, churning losses, and traction coefficients directly influence vehicle range and overall energy consumption. Furthermore, electric potential within drivetrains can accelerate bearing degradation through electrical discharge damage and lubricant film breakdown. Scalability, durability and long-term reliability therefore, become central challenges - particularly for applications where operational loads and duty cycles are severe.
Goal
The primary objective of ReET is to design, develop and validate a high-efficiency, magnet-free electric traction motor tailored for EV applications. The system will be fully integrated and demonstrated, ensuring industrial relevance and real-world applicability.
Impact
The ReET project will deliver transformative impact across technological, industrial and societal dimensions by accelerating the transition toward sustainable electric transport. By developing a high-efficiency, magnet-free traction motor and validating it under real operating conditions, ReET directly addresses one of the most critical bottlenecks in transport electrification: scalable, durable and resource-independent powertrain technology.
