Abstract:

A new electromagnetic levitation system device is proposed, which uses the electromagnet array and the permanent magnet to provide three-dimensional electromagnetic levitation force. The system has the advantages of the large suspension force, the distribution magnetic field and wide range movement over the traditional electromagnetic suspension system, and it can significantly improve the efficiency of the system. The characteristics and the synthetic magnetic properties of the magnetic levitation force are analyzed by the finite element method before the relevant experiments. The results show that the suspension system so designed can be used for the large air gap with good stability and control.

Key words: magnetic levitation system, permanent magnet, finite element method, large air gap
