1 Nano-crystalline and amorphous cores Products and applications Casting issues and developments ZVEI Workshop Dr. Swen Graubner, SEKELS GmbH Berlin

2 Nanocrystalline and amorphous cores Introduction to casting process Alloy-specific properties Some applications Summary

3 Amorphous structure crystalline Ordered structure High density amorphous Short range order No long-range order Some crystalline effects do not occur

4 Amorphous structure metallic glass real glass From:

5 Production of amorphous strip melting furnace induction coil liquid metal 1300 C ceramic nozzle cooling rate: Kelvin/s to (fast) automatic winder casting wheel 10 C amorphous metallic strip, µm speed: 100 km/h (60 mph) One process step from melt to final strip thickness

6 How to grow nano-crystals? Start with amorphous material Heat it up to C Let many small crystals grow BUT stop them from getting too big and to merge! Grain size very important

7 Coercivity [A/cm] Why is nano-crystalline soft magnetic? amorphous nanocrystalline crystalline Zero magnetostriction High Curie temperature Low temperature dependence No Nickel or Cobalt Low losses D 6 1/D 1nm 1µm 1mm Grain size D

8 Coercivity [A/cm] Why is nano-crystalline soft magnetic? amorphous nanocrystalline crystalline Zero magnetostriction High Curie temperature Low temperature dependence No Nickel or Cobalt Low losses D 6 1/D 1nm 1µm 1mm Grain size D

9 Saturation Flux Density [T] Soft magnetic alloys for electrotechnical applications 3 ideal 2 real crystalline (metal) Nanocrystalline powder 1 amorphous ferrite ,000 Coercivity [A/m] Mother nature likes huge varieties (and busy engineers )

14 Core losses in W/kg Alloys for power chokes Typical core losses (columns) in W/kg (f = 25 khz, B p = 0,2 T) and saturation flux density (circles) of choke materials (losses should be low, flux density high )

15 Core losses in W/kg Saturation Flux Density in T Alloys for power chokes , ,5 0 0 Typical core losses (columns) in W/kg (f = 25 khz, B p = 0,2 T) and saturation flux density (circles) of choke materials (losses should be low, flux density high )

16 L (H) in % Linear chokes with amorphous c-cores Inductance stiffness Air gap can be used to adjust inductance Good energy storage capability Linear L-characteristic ( stiffness ) airgap 100% 75% 50% 25% 0% Amorphous C-Core SiFe-Powder MPP Sendust H in A/cm

17 Applications of amorphous & nanocrystalline cores Power Chokes Common Mode Chokes Current Transformers Power Transformers Saturable Reactors

18 Common mode chokes Common Mode Choke Trick: compensating fields Small size possible No saturation by nominal current Removes noise signals I 1 compensated!!! I 2

19 Common mode chokes Common Mode Choke Trick: compensating fields Small size possible No saturation by nominal current Removes noise signals Non-compensated I 1 I 2

20 Nanocrystalline cores for CMC Important parameters: Damping behavior Permeability Frequency dependence Saturation magnetization Size/weight Temperature stability Price
