Characteristics of a superconducting magnetic bearing.

Author(s) : OKANO M., FUCHINO S., AGATSUMA K., TAMADA N., ISHII I., ONISHI T.

Type of article: Article

Summary

The authors describe the levitation force characteristics, the force relaxation caused by flux creep, and the bearing loss under high rotational speed, of a disk-type superconducting bearing at a temperature of 77 K, as well as the rotational characteristics of pinning-type superconducting radial bearings. The rotor in which a permanent magnet is supported by the pinning force in the superconductor can be safely operated at high rotational speeds.
