Abstract: A novel detent-force-based magnetic suspension system (DMSS) was presented. The topological structure and operating principle of DMSS were analyzed. Using finite-element analysis method, the magnetic field distribution and the characteristics of the axial, radial and whole levitation force with the displacement were studied respectively. The simulation results show that the DMSS can generate larger levitation force than common levitation system, and its levitation mode is a passive suspension in the axial without external control. The feasibility and theoretical analysis of the DMSS were verified. It is helpful for the further analysis and industrial applications of DMSS.
