Our group has developed a new conveyer using superconducting levitation. The conveyer is composed 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 using 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, characteristics of magnetically levitated superconducting conveyer are studied when the levitated table moves in the horizontal direction.
