The purpose of this work is to clarify the correlation between magnetic reluctance distribution and structural parameters in linear pulse motor (LPM). By clarifying correlation between them, we can control magnetic characteristics of LPM and adapt them to applications. In this paper, we show as follows:
(1) We discuss the correlation between harmonic of gap reluctance and structural parameters in LPM by using multiple regression analysis.
(2) The result of analysis show there is a strong correlation between magnetic reluctance and structural parameters of gap section, gap length, pitch, teeth width and depth of slot.
The magnetic reluctance of air gap is calculated by using a, linear two-dimensional finite element method with scalar potentials. Harmonics of reluctance are obtained through FFT. Multiple correlation coefficients between harmonic and structural parameters are calculated on a linear multiple regression model. We test about regression coefficients at a significance level of 1% and clarify correlation between harmonic and gap length etc.
