Type: article

Abstract: This study discusses the electromagnetic characteristics of superconducting magnetic bearings (SMBs) using ring-shaped permanent magnets (PMs) and laminated high-temperature superconducting tapes. The two ring-shaped PMs of different magnetization structures are applied for SMBs to compare thrust electromagnetic force and rotation loss. The measurement results of maximum thrust magnetic force using axial magnetization ring-shaped PM reached almost 60 N. Furthermore, the rotation loss characteristics indicated that the rotation loss with the SMB was less than 1.5 W in the range of 1,000–1,600 rpm.
