This paper presents a novel method for the calculation of eddy current loss in coreless stator axial field permanent magnet (AFPM) machines based on a universal parametric magnetic network model. To account for threedimensional field effects in an AFPM machine, a multilayer modeling method is used to estimate both the axial and tangential magnetic field component in the air gap. The winding eddy current loss is calculated using the results of magnetic network analysis, taking into account 2-D and 3-D effects …
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
