Harmonic characteristics of SC coil configuration for EDS maglev to reduce leakage flux

Abstract

An improved configuration of SC coils, whose end coils are small, is studied to reduce their leakage flux. This paper examines the harmonic characteristics when the improved configuration of SC coils is applied to the 120‐degree coil pitch ground coil. An adequate combination of length and mmf in the end coils can provide proper performance of harmonics and basis. © 2009 Wiley Periodicals, Inc.
