Magnetically Levitated Conveyer Using High Tc Superconducting Magnetic Bearings (SMBs) and Its Dynamic Characteristics
Our group has developed a new conveyer using superconducting levitation. The conveyer is com-posed of a levitated table and a conveying table. The gap between levitated table and conveying table is detected by using a Hall sensor on the superconductor. The position of the table is controlled by us-ing the PD control. In this paper we discuss a superconducting magnetic bearing (SMB) with a central superconductor. A central superconductor improves stiffness of each direction. In addition, character-istics of magnetically levitated superconducting conveyer are studied when the levitated table moves in the y direction.
