Why is the transformer made of sliced silicon steel sheet?
I feel the circulation should be a solid current, not like a ring like plane linear current, the section steel sheet with insulation effectively blocking the current along the Z direction, so reduce the heat, I guess...
If you press the algorithm then changes the resistance type, the whole core sheet resistance and mutually insulating silicon steel sheet piling resistance type natural don't ha... Obviously... Silicon steel sheet resistance more.......
The magnetic core of a transformer has eddy current losses at work, and the direction of the eddy is perpendicular to the direction of the magnetic fieldIf the whole iron core is used, the resistance is very small in the direction of the vertical magnetic field line, the eddy current will be large and the loss will be largeTherefore, magnetic cores are usually made of materials with higher resistivity, or processed into slices in a superposition mannerThe resistance values in the direction perpendicular to the magnetic field line reduce eddy current losses.
