WebHence the eddy current loss can be reduced in transformers, electric motors and alternators by using thin electrically insulated plates stacked together to form a core instead of solid ones. By doing so, eddy voltages can be reduced and the resistance to eddy currents can be increased which will finally result in lower core losses in the machines. Web6. Eddy currents are setup in any metallic block which is in the vicinity of changing magnetic fluxes. These primarily cause heat losses, and in certain cases causes damping of the relative motion between the metallic block (where the currents are induced) and the …

WebThe eddy current loss is proportional to; Eddy Current loss (We) = K x I2 R (Where K is the eddy current constant) From above it is clear that the higher the current, the higher is the loss. The solid core has a larger cross-section area, therefore it has lower resistance. According to Ohm’s Law, the lower resistance causes a higher current ...
