Amorphous Alloy Core For High-Speed Motor
- Ultra-Low Core Loss: ≤ 0.2 W/kg @ 1.5 T, 50 Hz; ideal for 400–20,000 Hz high-frequency use.
- Thin Ribbon Construction: 20–30 μm amorphous ribbons minimize eddy-current loss.
- Lightweight Efficiency: 25% lower density than electrical steel for reduced rotor inertia.
- Precision Balance: Engineered for vibration-free rotation above 60,000 RPM.
- High Saturation Flux Density: Up to 1.56 T enables compact, high-output motor design.
