Abstract

This paper proposes the calculation method of magnetic coupling coefficient of the contact-less energy transmission system for the linear servo motor by the three-dimensional finite element method with a variation of the secondary core positions. The primary, secondary self and leakage inductances, and the capacitances of a resonant circuit are calculated by the finite element analysis results. From these values, the magnetic coupling coefficients are obtained. The secondary voltages and currents at the secondary core positions are calculated by using the resonant circuit and compared.
