The Fundamental Investigation for Suitable Planning of X-YLIM

Abstract

As for the structure of the X-YLIM, two kinds of windings (one in the X direction and the other in the Y direction) were wrapped respectively around two horizontal axes, X and Y. By these windings it became possible to generate a two-dimensional travelling magnetic field and drive the moving part in any direction within the two-dimensional place.
In this paper, we take a three-dimensional one-pole model of X-YLIM into consideration, and used three-dimensional finite element method as the analytic technique. This paper examines the followings to obtain guidelines for the future: (1) the flux density with respect to the height of the primary iron core. (2) the flux density with respect to the yoke thikness. (3) the flux density with respect to the primary current. (4) the relationship between the air gap and the thrust.
