Silicon steel used in lamination mainly reducesHysteresis loss,Eddy current losses,Copper loss. In order to minimize the eddy currents more,magnetic core is laminated . The hysteresis coefficient of silicon steel is less, so hysteresis loss can be reduced.
Introduction:
Single phase UI core is made by the silicon steel strip. The model
of UI lamination in standard sizes is from
UI 20-UI 100.The gap sizes of transformer lamination core can be customized.
