Application of 2G-Tape for Passive and Controlled Superconducting Levitation

Second generation (2G) superconductor wires have been used for several applications. This work presents a preliminary study of superconducting magnetic bearings (SMB) using 2G wires.

Description
Summary:Second generation (2G) superconductor wires have been used for several applications. This work presents a preliminary study of superconducting magnetic bearings (SMB) using 2G wires. A double pancake superconducting coil (DPSC) was implemented to test the 2G wire in levitation technology. The coil was projected by simulations with the Finite Element Method (FEM). The 2G wire can be used for two types of SMB: linear (for MagLev vehicles), or rotational (for flywheels). In both applications the wire can be connected as a closed loop coil (for passive levitators), or as an opened coil (for applications where a controlled levitation gap is desired). A rotational SMB was made to investigate the levitation force between the DPSC and a permanent magnet cylinder showing promising potential of this application.
