Segmented Amorphous Stator Laminations
- Ultra-Low Core Loss: ≤ 0.2 W/kg at 1.5 T, 50 Hz—70% lower than silicon steel.
- Segmented Core Design: Reduces stress and deformation during assembly or high-speed operation.
- Custom Geometry: Segments can be optimized for different stator diameters or pole configurations.
- Superior Thermal Performance: Amorphous alloys dissipate heat efficiently and resist localized hotspots.
- Lightweight Construction: Up to 25% lower density compared to electrical steel laminations.
