A vibration suppression strategy for the dual three-phase permanent magnet synchronous motor (PMSM) in five degree of freedom (DOF) magnetic levitation system is proposed in this paper. Firstly, magnetic bearings (MBs) are designed to support the high-speed operation of the dual three-phase PMSM. Secondly, in order to suppress the vibration caused by the motor, the radial electromagnetic forces generated by the air gap magnetic field interaction are analyzed. After that, to suppress the vibration of the whole rotating shaft, fifth and seventh harmonics are injected in the windings of the dual three-phase PMSM by synchronous frame PI regulators. Amplitude and phase of harmonic currents are adjusted to counteract the radial electromagnetic forces, and then the vibration can be suppressed accordingly. Simulation results verify the effectiveness of the proposed strategy.
