Parameter analysis of electromagnetic braking using fully nested and two-way ANOVA

Abstract

This paper presents the statistical analysis that was used to define optimized parameter for the electromagnetic braking using eddy current study. It illustrates parametric study on four different parameters affecting the braking performance using eddy current which are air-gap, number of electromagnet turns, current induced and disc thickness. These four parameters are defined as the factors which contribute to the reduction of RPM speed as the effect. Fully nested ANOVA was used as the first analysis to determine two most significant factors to eddy current braking system. Then, two-way ANOV A was applied to clarify the most significant factors to be used as the controllable parameters in the verification study. Results from both ANOVA test shows that current induced and air-gap are the two most significant factors that affected braking using eddy current.
