摘要：
Cores of electrical machines are usually laminated to reduce eddy current loss. Punching and pressing of the electrical sheets can deteriorate the interlaminar insulation and hence, can cause interlaminar currents to flow across the stack. In this paper, eddy current loss due to interlaminar currents is studied considering the conductivity of the sheets in both across and along the lamination direction. A statistical study of random interlaminar contacts and thermal measurements are also presented in this paper.
