Why should the transformer core be made of silicon steel instead of the whole core?
Electrical eddy current loss of ferromagnetic material and inversely proportional to the thickness of the steel plate, the square of silicon steel sheet is in electrical steel by adding a small amount of silicon and made larger resistivity, with core laminated silicon steel sheet, iron loss is small, so the core of the transformer with stacked of silicon steel sheets instead of whole steel.
Transformer (Transformer) is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are voltage conversion, current conversion, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer) and so on. According to use can be divided into: power transformers and special transformers (electric furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, mine, variable audio transformers, intermediate frequency transformers, high frequency transformer, transformer, instrument transformer, the impact of electronic transformer, reactor, transformer etc.). Circuit symbols are often used as the beginning of numbers. Examples: T01, T201, T, etc..
When the windings of the transformer flow through the AC current, they will produce hysteresis losses and eddy current losses in the metal, collectively referred to as iron losses. Hysteresis loss is related to the hysteresis loop area of ferromagnetic material. The hysteresis loop of silicon steel sheet is narrower and the hysteresis loss is smaller.
