  • Rotary permanent magnet electrodynamic suspension device and permanent magnet electrodynamic suspension method using the same
    Patent number: 12214671
    Abstract: A rotary permanent magnet electrodynamic suspension device includes drive systems, a suspension system, an isolation layer. The drive systems are symmetrically provided in an axial direction of the suspension system. The isolation layer is provided between the suspension system and each drive system. The suspension system includes a magnetic wheel, a non-magnetic conductor and a support. The non-magnetic conductor has electromagnetic induction with the magnetic wheel. The support and the magnetic wheel are both ring-shaped, and the magnetic wheel is sleeved on an outer circumference of the support. The drive systems are configured to drive the magnetic wheel to rotate through electromagnetic induction. The magnetic wheel includes an annular array of permanent magnets to form four pole pairs based on radial magnetization and tangential magnetization. A permanent magnet electrodynamic suspension using the device is also provided.
