Abstract

An axial-gap switched-reluctance motor (SRM) was designed with high power density by using a mathematical model. To shorten the analysis time by 3D finite element analysis (3D-FEA) to calculate the torque characteristics of the axial-gap SRM, an analytical method was proposed and used for designing the SRM. The key feature of the method is expressing the mutual flux with a mathematical model by employing transient analysis using pre-processed inductance tables. A 3.7-kW prototype axial-gap SRM designed was designed by this method and tested. According to the test results, output density of the prototype SRM is 16% higher than that of conventional induction motors.
