The oriented silicon steel grains are ordered, and the grains of the non-oriented silicon steel are disorderly arranged. Non-oriented silicon steel is mainly used in stators and rotors of electric machines, compressors, large hydro-generator units and the like. Oriented silicon steel is generally used in transformer cores and some motors.
The requirements for silicon steel sheets for generators and transformers are the same: they all require low iron loss and good magnetization characteristics.
The lamination factor is high, but the transformer is generally made of oriented silicon steel. Non-oriented silicon steel sheets for generators.
