N2 - In high power density electrical machines, the challenge of proximity loss estimation in the winding is crucial due to its substantial influence on efficiency and thermal loading. In this study, an innovative approach using magnetic equivalent circuit (MEC), exploiting linear superposition of magnetic flux leakage, is utilized to estimate the time-varying proximity loss induced by any arbitrary current rapidly and accurately. The proposed method is implemented on a stator slot of an electrical machine. The results of this method are highly consistent with those obtained from Finite Element Analysis (FEA), while much less computational time is required in comparison, showing the efficiency and accuracy of the proposed method.
