Eddy-current loss of NdFeB permanent magnets (PMs) is widely analyzed in PM motors. This paper proposes a coupled 2-D transient finite-element analysis (FEA) of the saturated core fault current limiter (SCFCL) and 3-D analytical model of PMs to evaluate eddy-current loss in SCFCL. The comparison between the result from coupled method and that from 3-D FEA verifies the applicability of the coupled...
In the ordinary saturable magnetically controlled reactors inserted in the legs with magnetic valves of smaller cross-sectional areas (VMCR), the flux concentrates in the legs due to the valves so the iron loss and noise are increased. In this paper, to reduce the iron loss and noise of VMCR, the structure of the valves is improved by using 3D nonlinear magnetostatic field analysis taking account...
