| Abstract: | The main source for the transformer noise is magnetostriction of grain-oriented silicon steel.In this paper, the effects of magnesium coating and phosphate coating on magnetostriction of grain-oriented silicon steel have been studied. The results showed that magnesium coating and phosphate coating could reduce the magnetostriction of grain-oriented silicon steel. Increasing the thickness of coating could decrease the hetero domain and 90 degree domain, and improve the noise characteristics of the oriented silicon steel. |
