Formula of hysteresis and eddy current loss

WebWhat is eddy current losses? If an eddy current of magnitude I flows through a core path of resistance r, it will dissipate energy in the form of heat according to the power equation power = I2R. Since this represents energy being expended for no useful purpose, it is considered as an eddy current loss, sometimes called iron loss. WebIron loss for, induction machine, consist of Hysteresis loss,and eddy current loss (at constant flux density (v/f=constant) Wi =Wh+We= Af+B (f) (f) OR Wi/f=A+Bf, where f is frequency of...
