- Abstract
- In this paper, we propose a structural modification to improve lévitation force of an EMS (Electro-Magnetic Suspension) C-type lévitation system operated by an electromagnet. When the size of the transport system is limited, a study has to be conducted on design techniques to allow maximum lévitation force within constraints. This study considered the shape of the stator teeth to improve the lévitation force without affecting overall size of system. In addition, slol design parameters resulting from changed teeth shapes were summarized. The shape with maximum lévitation force was derived by analyzing the magnetic flux contributing to the lévitation force and the leakage flux according to the size of the design variable. Finally, the validity of the study was verified by comparing the lévitation force results of the basic and improved models through FEA (Finite Element Analysis).
