Abstract: Three mechanisms, magnetically levitated by permanent magnets are introduced and analyzed in respect of their balance and stability based on the nature of attraction and repulsion by permanent magnets. The barycenter of the vehicle body is above the magnetic suspension mechanism in one mechanism, below it in the another two. The analysis shows that, among the three mechanisms presented in this paper, the suspension mechanism combining magnetic attraction and repulsion can be statically stable, while the other two can not.
