Abstract
As a two-dimensional movement motor, the double-sided X-Y linear synchronous motor without armature core has been proposed as a precise positioning device. The linkage flux density and thrust are studied analytically by using three-dimensional numerical analysis. The results show that this motor has sufficiently large values on them and the satisfied thrust per mass in the air core type for the double-sided pole configuration. There is little ripple in the thrust in the motion to any position as there is no detent force.
