Magnetic levitation, or Maglev, is the use of magnetic force to overcome gravity and suspend objects in mid-air. However, achieving stable levitation is not easy, primarily due to the lack of a stable equilibrium point. To achieve levitation, it must be stable, meaning that if the levitated object is disturbed in any direction, there will be a restoring force that brings it back to balance once the external force is removed. Maglev can be classified into active and passive types. The role of magnetic levitation induction coils is to detect deviations of the levitated object from its normal levitation point using methods such as photoelectric and magneto-electric detection, and then adjust the current in the electromagnets to keep the object near the levitation point.
Layered winding of magnetic levitation induction coils ensures good performance.
All products undergo quality inspections.
Independent hollow coils.
Custom packaging of magnetic levitation induction coils ensures that they are not damaged during delivery.
To ensure the reliability and longevity of the coils, we ensure tight arrangements for self-adhesive wire winding processes.
Coils produced using the potting process for magnetic levitation induction coils have lower composition costs and lighter weight, can eliminate potential leaks, and protect windings and high-temperature performance.
The process of generating lift with magnetic levitation induction coils occurs when DC current flows through the inductance, creating fixed magnetic lines around it that do not change with time. However, when AC current passes through the coil, the magnetic lines around the magnetic levitation induction coil vary with time. The changing magnetic lines induce an electromotive force at both ends of the coil, equivalent to a “new power source.” When a closed circuit is formed, this induced electromotive force generates induced current. According to Faraday’s law, the total amount of magnetic lines produced by the induced current should prevent changes in the original magnetic lines as much as possible. Since the changes in magnetic lines come from variations in the external AC power source, magnetic levitation induction coils have the characteristic of preventing current changes in AC circuits. Induction coils have mechanical properties analogous to inertia.
