Firstly, it is necessary to use steels with lower magnetic losses for the fixed body parts of transformers, motors, and generators. Therefore, electrical steels are produced by adding silicon to the steel material, which have high permeability and low energy losses.
This type of steel, known as electrical steel or silicon steel, is becoming increasingly widespread due to its ability to enhance the efficiency of electrical equipment, especially with the influence of advancing technology.
Electrical/Silicon steels are divided into two categories based on the production of stator and rotor laminated cores: Non-oriented/Grain-oriented structure and Oriented/Grain-oriented structure.
