What is Nano-Crystalline Core? FINEMET, NANOPERM or VITROPERM are the various brands of the soft Nanocrystalline alloy, which are available in the market for several years. Iron-based NanoCrystalline Core is a simple but revolutionary technology which produces fragile ribbon from very cheap raw material like silicon and iron. Amorphous NanoCrystalline Core allows lighter, smaller and energy-efficient, and used in inverters. Amorphous magnetic metal has high permeability.
Production Process: Using the ‘Rapid Solidification’ process, a stream of molten metal is sprayed at 1300 degree C in between a narrow ceramic nozzle, then directly into a fast rotating and water cooled copper roller. Continuous Amorphous Ribbon of 20-micrometer thickness is obtained at a speed of 100 km/hr by this process.
Advantages of Nano-Crystalline Core:
Lesser Weight Less copper loss because of the decreased number of turns Lesser Volume More significant safety issues and very robust Increased temperature range
Available Products: Nano-Crystalline Cores are accessible in the form of stadium shaped tape-wound or toroidal cores. This metal is brittle, and it only requires protection against mechanical forces. The cores are extremely robust once they are coated or boxed. Its magnetic properties are that it is highly linear and not dependent on temperature. The major products are:
Nano Crystalline Cores used for Inductive Cooking Nano Crystalline Cores used as Power Supply Switch Nano Crystalline Cores used in Filters Nano Crystalline Cores used for Frequency Converter Nano Crystalline Cores used in Solar Inverters Nano Crystalline Cores used for Welding Equipments Nano Crystalline Cores used in Electric Automotive Cars Nano Crystalline Cores used for Uninterrupted Power Supply Nano Crystalline Cores used for Air Condition Nano Crystalline Cores used in Wind Generators
Now the cores sizes vary from 10 mm to near about 300 mm of the outer diameter. But in the markets air-gapped or cut cores should be present, but actually, they are not. SOURCE URL: https://bit.ly/2XGWgWB
