Formula for Eddy Current Power Loss It is difficult to determine the eddy current power loss because the current and resistance values cannot be determined directly. Experiments have shown that eddy current power loss 'e in a magnetic material can be expressed as Pe = keBm2 t2f2V'watts where k = eddy current coefficient and its value depends upon the nature of the material. Bm, = maximum flux density in Wb/m2 t = thickness of lamination in m f = frequency of flux in Hz V = volume of material in m3 | |
