Abstract

Double-side linear pulse motor(DSLPM) has more advantages than single-side linear pulse motor because noise and vibration can be considerably decreased by countervailing the normal forces, which is generated between two stators and mover. However, DSLPM has more complicated magnetic flux path and layout of stator pole toot/mover tooth rather than single-side linear pulse motor In this paper, DSLPM is designed and fabricated by considering the air gap magnetic density, shape of tooth and slot. In order to verify the characteristics of DSLPM, the air gap magnetic flux density is analyzed by 2D FEM and the magnetic flux path is analyzed by 3D FEM. Also the static thrust forces is obtained with the analyzed results.
