Abstract

Eddy current loss of NdFeB permanent magnets (PMs) are widely analyzed in permanent magnet motors. And it's necessary to analyze this issue in saturated core fault current limiter (SCFCL). This digest discusses the coupled 2-D finite element analysis (FEA) of the SCFCL and 3-D analytical model of PMs to evaluate the eddy current loss of PMs in a SCFCL. The comparison between result from coupled method and that from 3-D FEA verifies the applicability of the coupled method in analyzing eddy current loss of PMs in SCFCL.
