Recharga Chargine develops RADAX, a hybrid axial-radial flux, direct-drive permanent-magnet generator architecture designed to increase power density and reduce weight and cost in multi-megawatt wind turbines. The company licenses this modular technology to established turbine manufacturers, allowing them to skip core generator R&D and integrate the architecture into their existing platforms.

Problem
As wind turbines grow larger, conventional generator architectures have become heavier, costlier, and more complex with every added megawatt. Scaling traditional designs requires more structure and active material, while gearboxes introduce failure modes and direct-drive alternatives shift the burden onto larger, heavier machines. The generator's cost curve has stalled even as blades and towers have continued to improve.
Solution
Recharga Chargine has developed RADAX, a hybrid axial-radial flux generator architecture that combines both magnetic flux paths in a single direct-drive machine. This design aims to deliver higher power density and a better balance of weight, efficiency, and cost compared to conventional topologies. The generator uses permanent-magnet excitation, eliminating excitation losses and slip rings, and is built from repeating modular segments so it scales across ratings without being redesigned each time. Rather than manufacturing turbines, the company licenses the architecture to established OEMs, supporting integration so the technology reaches real wind farms faster.
Target Audience
Primary customers are wind turbine OEMs and manufacturers seeking to improve generator performance without undertaking years of internal R&D, as well as investors and partners in the clean energy transition.
Features
- Hybrid axial-radial flux topology that uses both flux paths in one machine to maximize useful magnetic work within the same envelope
- Direct-drive, permanent-magnet excitation with no gearbox, excitation losses, or slip rings
- Modular architecture built from repeating segments, enabling scaling across power ratings without full redesign
- Technology licensing model that lets manufacturers keep their product and brand while skipping core generator R&D
- Engineering support for evaluation, integration, and deployment into existing turbine platforms
