A motor bracket, an axial flux motor, a flywheel, and an inner stator, a coil, and a permanent magnet of a five-degree-of-freedom magnetic bearing are coaxially arranged in a shell from top to bottom. The flywheel consists of an upper layer, a middle layer, and a lower layer which are continuous. An upper annular groove is formed in a middle of a flywheel upper annular layer of the upper layer. The axial flux motor is placed in the upper annular groove. An annular inner groove, a middle-layer annular cavity, and a lower annular groove are communicated with each other and jointly used for placing the inner stator, the coil, and the permanent magnet of the five-degree-of-freedom magnetic bearing.
