The application discloses a full magnetic suspension system based on bidirectional active axial force of a rotor and a control method thereof. The full magnetic suspension system is provided with an axial force winding 3, and a magnetic field rotating synchronously with the rotor generated on the winding can generate stable axial forces in two directions of attraction and repulsion to compensate for axial hydraulic force.
