Design concept and analysis of a magnetically levitated linear slider with non-contact power transfer

This paper presents the design concept of a magnetically levitated linear slider with non-contact energy transfer, and an analysis of the major components of the design. An open-end generator is introduced to achieve non-contact energy transfer to the levitated platform. Utilization of non-contact energy transfer will overcome difficulties related to charging batteries. Furthermore, we have proposed an improvement for a hybrid electromagnet to achieve better passive lateral alignment under zero power control. The results of FEM analysis and practical testing show that the concept is promising for further study with a prototype system.
