Why does the motor use the non oriented silicon steel sheet and the transformer oriented silicon steel sheet?
The difference between the non oriented silicon steel and the oriented silicon steel sheet is that the permeability of the oriented silicon steel sheet is higher along the roll direction, so the excitation loss of the oriented silicon steel is no less than that of the non oriented silicon steel sheet.
The function of the transformer is to transmit the electric energy. The smaller the loss, the better, and the requirement of the motor is not as high as that of the transformer. Therefore, the transformer should adopt the oriented silicon steel sheet to meet the requirements, and the motor can be made of non oriented silicon steel sheet.
