The Nano Crystalline Cores are made from Iron based Soft magnetic
material. These are derived from Crystalline Amorphous ribbon and
subsequent heat treatment around 500-600 C .The typical grain size is
only 10 nanometers hence the name Nano Crystalline.
There appears to be no limitation to the type of cores that can be
manufactured from Nano Crystalline material: C-cores, E-cores , Uncased
Toroids, Cased Toroids, Multiple cuts Gapped Toroids, etc.
Nanocrystalline metals Cores are ideally suited for diverse range
of applications such as:- Frequency of operation is from 50 Hz to MHz
range
Common Applications are
Switch Mode Power Supply Common Mode Choke Uninterruptible power
systems Pulsed welding equipment Power inverter (e.g. solar inverter)
Wind generators Frequency converter Energy Meters Current Sensors
Benefits
Nanocrystalline material has the potential as lower cost alternatives
to the costly Cobalt-based Amorphous material in many applications.
This is due to the excellent soft magnetic properties. Extremely Low
Coercivity High Permeability Low Energy Losses High Saturation Flux
Density
