Notes:
Doubly oriented 3% Si-Fe having high permeability was prepared by a cross-rolling method and secondary recrystallization. We examined two applications of this doubly oriented material. One application is a three-phase power transformer. Watt loss of the transformer using doubly oriented 3% Si-Fe in yokes was found to be lower than that of the transformer using singly oriented 3% Si-Fe, especially at high induction. The lower loss of the transformer using doubly oriented 3% Si-Fe was explained by magnetic domain wall movement observation and FEM calculation. The magnetic flux can rotate more smoothly in the yokes of the transformer using doubly oriented 3% Si-Fe than in those parts of the singly oriented 3% Si-Fe transformer. Doubly oriented 3% Si-Fe is also effective to decrease the loss at "hot point.'' Another application is a punched U-I shaped core, in which the flux is rotated at the corner. Doubly oriented 3% Si-Fe core was magnetized to high induction easier than those of singly oriented 3% Si-Fe and nonoriented 3% Si-Fe. These results show that doubly oriented 3% Si-Fe is one of the best materials for the applications in which magnetic flux is rotated.
