Dual Flux Topology
A radial machine architecture that channels two coupled flux paths to deliver torque density beyond conventional PMSMs, without sacrificing thermal headroom.
Technology
Dual Flux Technology™: a new architecture for electric motor design.
Dual Flux Technology™, a new approach to electric motor design that combines the strengths of Electrically Excited Synchronous Motors (EESM) and Permanent Magnet Synchronous Motors (PMSM) into one advanced hybrid solution.
The technology
The Dual Flux motor architecture
Dual Flux Technology™ is Talos Technology's proprietary electric motor architecture that combines the strengths of Electrically Excited Synchronous Motors (EESM) and Permanent Magnet Synchronous Motors (PMSM) within a single machine. By creating two magnetic flux paths inside one motor, it gives manufacturers a new way to balance performance, efficiency and material cost, delivering high torque density and strong part-load efficiency while reducing dependence on rare-earth magnets.
Architecture
Two flux paths. One coherent machine.
Built to reduce magnet dependency while maintaining exceptional efficiency and performance across different operating conditions.
- 01Higher continuous torque density
- 02Improved efficiency at part-load
- 03Better fault-tolerance modes
- 04Reduced rare-earth dependency
