Repulsive Magnetic Levitation System

This magnetic levitation system uses four electromagnets, three Hall effect sensors and a large permanent ring magnet to levitate a small permanent magnet. The repulsive force between two permanent magnets enables levitation of heavier objects with greater efficiency. The small magnet levitates indefinitely without any disturbance and it can also be forced to rotate slowly. In addition, the magnet will still levitate even when the base is tilted.




  • Gap distance: 2 cm
  • Maximum additional weight: 250 g
  • Size: 10 cm x 10 cm x 2 cm base, 4 cm x 1 cm levitating magnet
  • Weight: 375 g base, 80 g levitating magnet
  • Power consumption: almost 0 W when the magnet levitates steadily
  • 3 Hall effect sensors (x, y and z position sensors), 1 temperature sensor, 4 electromagnets (x and y position actuators)
  • Novel MIMO controller with auto zero

This repulsive magnetic levitation system is specifically designed to be used with the HILINK or RAPCON platform. Please see the quick reference manual for its technical specs. We also have various different standalone units that can levitate up to 1000 g additional weight. Three examples of such units are shown below.


  • Floating distance: 1.5 - 2.0 cm
  • Maximum additional weight: 200 g
  • Base: 10 cm x 10 cm x 2 cm metal
  • Four bright white LEDs on the base


  • Floating distance: 1.5 - 2.5 cm
  • Maximum additional weight: 200 g
  • Base: 15 cm x 15 cm x 3 cm acrylic
  • LEDs are powered from base via "wireless power transfer"

  • Floating distance: 1.5 - 2.0 cm
  • Maximum additional weight: 200 g
  • Base: 18 cm x 18 cm x 2 cm acrylic
  • Eight bright blue LEDs on the base


The wireless power transfer subsystem can transfer approximately 0.5 W using resonant inductive coupling. It is possible to transfer more than 10 W across 10 cm or more. We can customize the standalone units per your specifications. Please contact us (info@zeltom.com) for more information.
