Analysis of Magnetic Forces and Supercurrent Distribution of Radial-Type High-TC Superconducting Magnetic Bearings

摘要

The superconducting magnetic bearings (SMBs) have been studied for the application to flyweed energy storage systems, where these SMBs are incorporated to support total weight or rotors without contacting them. In designing these SMBs, the levitation force should be reasonably predicted. To predict this force, practical analytical method should be developed. This paper deals with the analysis of levitation force characteristics for practicable radial-type SMBs with multiple supercon- ducting bulks.
