dc.description.abstractVarious techniques have been investigated and proposed for core loss minimiza-tion in electrical machines. Nevertheless, many of such methods are mostlycomplicated and not suitable for consideration at a preliminary design stage. Inthiswork,asimplifiedprocedurewhichusesananalyticalapproachtominimiz-ing the field’s losses of an Axial Flux Permanent Magnet Alternator (AFPMA),is presented. First, the output equation of an AFPMA is referred, and then theminimization of the losses is investigated by analytical differential equations.The result of the derived-specific magnetic loading is investigated using threedifferent core materials, namely 35RM300, 50JN350, and 65JN800, and is foundto reduce with increased frequencies. The 35RM300 core material gives themaximum specific magnetic loading and minimum power loss at investigatedfrequencies of 50 to 500Hz. Although the 35RM300 core material gives the bestperformance, the optimal values are only determined as suitable by the manu-facturer’s design criteria. This study is a key indicator for a simple and efficientcore material selection in the design of a Wind-Powered AFPMA without theneed for complicated analyses at the preliminary design stageen_US
