Transformer core classification

Transformer core When making any transformer, manufacturers try to achieve maximum magnetic coupling between the two inductors. The magnetic coupling can be increased many times by using ferromagnetic material or iron powder as the magnetic core. A pair of inductors wrapped around a ferromagnetic core has a better coupling coefficient than an air-core transformer. However, the use of ferromagnetic cores has its own

Characteristics of Nanocrystalline Materials

1. High magnetic induction: the saturation magnetic induction Bs=1.2T, which is twice that of permalloy and 2.5 times that of ferrite. The power density of the iron core is large, which can reach 15 kW to 20 kW/kg. 2. High permeability: The initial static permeability μ0 can be as high as 120,000 to 140,000, which is equivalent to permalloy. The magnetic permeability of the iron core of the power transformer is

Introduction to the characteristics of nanocrystalline cores

On the one hand, eddy currents can be isolated, and the data are suitable for higher frequencies; on the other hand, due to the gap effect between particles, the data have low permeability and constant permeability; due to the small particle size, there is basically no skinning phenomenon, and the permeability varies with frequency. The change is relatively stable; in addition, the powder core can be made into vari
