A maglev power generator has a frame, a transmitting shaft, two electricity generating sets, two axial vibration-proof sets, two maglev assemblies, and two radial vibration-proof sets. The transmitting shaft longitudinally extends within the frame. The two electricity generating sets, the two maglev assemblies, and the two radial vibration-proof sets are connected to the transmitting shaft. Each axial vibration-proof set contacts a respective end of the transmitting shaft. The transmitting shaft suspends within the frame and is able to rotate without contact with the frame. The axial vibration-proof sets, the maglev assemblies, and the radial vibration-proof sets provide the transmitting shaft with magnetic forces radially and axially to prevent the rotating transmitting shaft from deviation. Therefore, the transmitting shaft is able to rotate with minimum power loss. The axial vibration-proof sets and the radial vibration-proof sets effectively offer a good vibration-proof function to let the transmitting shaft rotate stably.
