This study investigated the effects of coil wire diameter (d), disc thickness (w), and holding gap (xt) on the response times and energy consumption of a flat-faced disc type of magnetic circuit. The design of experiment (DoE) was created using the Taguchi L18 orthogonal array approach, with two levels for xt and three levels for d and w. Then, for each configuration in the DoE, the opening time (to), the energy consumption (Eo), and the closing time (tc) of the magnetic circuit were determined using the MATLAB/Simulink model validated with test data. Signal-to-noise (S/N) analysis was applied according to the smaller-the-better performance criterion to obtain the optimal parameter combination and priority order that would individually minimize to, tc, and Eo. The percentage contribution of each parameter was also evaluated using the variance analysis (ANOVA). In all cases, the most effective parameter was found to be wire diameter (d), and the optimal combinations for each target differed from one another. Therefore, grey relational analysis (GRA) was applied to the DoE results to derive the optimal combination for multiple requirements.
