Flender introduced the GENERA wind turbine generator concept, which provides power densities reaching 700W/kg. This announcement represents a new research-stage design that avoids rare earth materials and simplifies turbine transport.
Why it matters
The design aims to reduce material input and lower project costs by enabling the transport of high-capacity turbine components using standard shipping infrastructure. This shift addresses the logistical constraints currently limiting the scalability of turbines exceeding 10MW.
The GENERA unit achieves a power density of up to 700W/kg and reduces total generator length by 25% compared to previous generations. These improvements facilitate the use of standard trucks and containers for power classes above 10MW.
The players
Flender
A global manufacturer of mechanical and electrical drive systems, including specialized generators for the wind energy sector.
The details
The system utilizes a double-fed induction generator, a configuration that uses slip rings to provide power to the rotor circuit, eliminating the need for magnets. By removing the requirement for permanent magnets, the design avoids reliance on rare earth materials while integrating cooling improvements that allow the unit to operate without external fans. The reduced physical length enables the generator to fit within standard nacelle dimensions while offering an option to use aluminium instead of copper for the windings.

The Tech Race
The GENERA concept competes directly with conventional permanent magnet designs that have long dominated the high-power turbine market. By removing rare earth dependencies, Flender aims to circumvent supply chain volatility and physical transport limitations associated with traditional 10MW systems.
Wind energy developers will gain the ability to transport larger turbine components using standard logistics, reducing the costs associated with specialized shipping for 10MW projects. The availability of these units remains tied to the commercialization phase following this concept unveiling.
The takeaway
The move toward rare-earth-free induction generators signals a shift toward more resilient supply chains in the utility-scale wind sector. Developers should monitor Flender for upcoming performance benchmarks and the eventual transition from conceptual design to commercial prototype orders.
