Abstract
A superconducting Maglev system suspended by EDS has intrinsically a negative magnetic damping. In order to improve the magnetic damping, we have studied a magnetic damper using linear generator by controlling the power factor of those coils. This paper presents the improved type which has larger magnetic damping by changing the arrangement of generator coils and controlling the zero phase current of those coils. By applying to the dqO analysis, we can obtain the relationship between the induced voltage, current of generator coils and magnetic damping. Besides, the characteristics of linear generator and magnetic damping are revealed by numerical examples.
