Nano Crystalline toroidal Cores

1

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.

-Nano Crystalline Cores Physical and Magnetic Properties

square-loop-properties

-Nano Crystalline Cores Application and Benefits

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
