  • MAGNETIC LEVITATION SYSTEM
    Publication number: 20230238857
    Abstract: The present application disclosed a magnetic levitation system, and the magnetic levitation system includes a stator, a rotor, and a magnetic coupling mechanism; the stator includes a stator winding mechanism for controlling the rotor to move away from or close to the axis direction of the stator. The magnetic coupling mechanism includes magnetic sources, and the magnetic coupling mechanism is magnetically coupled with the rotor through the magnetic sources to drive the rotor to rotate around the axis direction of the stator. The magnetic levitation system decouples the magnetic circuit that drives the rotor to move from the magnetic circuit that drives the rotor to rotate, so as to reduce control difficulty, enhance stability, and reduce torque fluctuations.
