| Research Abstract |
As innovative technology for improving quality and productivity of nonmagnetic thin plates, an alternating ampere force type magnetic levitation and conveyance system was fabricated and evaluated. It was experimentally proven that the system increased levitation force while suppressing eddy currents inside a magnetically levitated thin plate and reducing heat loss. Furthermore, it was verified that propulsion force was given simultaneously with levitation, guidance, and ampere force to the plate. In parallel with that, electromagnetic separation tests of stacked plates utilizing the transient ampere force were carried out. As a result, it was found that the ampere force was effectively added to the transient eddy current induced in a thin plate by movement of permanent magnets.
