摘要：

In　this　paper,　we　consider　a　kind　of　rotor-active　magnetic　bearing　of　nonlinear　system.　The　average　equations　of　the　system　are　in　the　form　of　a　perturbed　polynomial　Hamiltonian　system　of　degree　5.　By　using　the　bifurcation　theory　of　planar　dynamical　system　and　the　Maple　symbolic　computation　program,　we　control　the　parameters　to　obtain　19　and　23　limit　cycles　under　two　different　conditions　and　the　configurations　of　compound　eyes　are　also　obtained.
