The thrust characteristic analysis of multi-separated winding LDM

다중 분할 권선형 LDM의 추력 특성 해석

This paper describes for new design method to improve respones characteristics of moving-magnet type LDM with volume reduction of slider back iron. To achieve the constant thrust of LDM through restraining saturation at the center core of stator excitation coil, double sided stator winding of LDM is proposed. We constructed new type LDM to prove the validity of design process. Analysis results through measurement and simulation of proposed multi-separated winding LDM were proved excellent in response characteristics and static thrust.
