Abstract

In this paper, a 3-degree of freedom levitation system is proposed, which contains the electromagnet array and the permanent magnet. The mathematical model is built, and the whole structure is optimized from three aspects, as magnetic force, controllability and resultant magnetic field. The efficiency of the new electromagnetic system is better than the traditional one. The characteristics and the synthetic magnetic properties of the magnetic suspension force are analyzed based on the finite element method. The experimental results show that the suspension system designed can be used for the large air gap with good stability and control.
