鉄心形状可変による X-Y LIM最適設計に関する検討

抄録

An X-Y linear induction motor (X-Y LIM) is a structure having two windings in the horizontal x - and y - axis directions. Exciting one winding generates a one-directional thrust, and a two-dimensional drive becomes possible by exciting two windings at the same time.
We investigated only one pole of an X-Y LIM having a three-phase, five-pole structure, and we used a three-dimensional finite element method as the analytical technique. The following characteristics were examined to obtain guidelines for future designs: (1) magnetic flux density and starting thrust with respect to primary current; (2) magnetic flux density and starting thrust with respect to gap; (3) magnetic flux density and starting thrust with respect to aperture ratio; and (4) magnetic flux density and starting thrust with respect to yoke thickness.
