Vibration and noise reduction is an important factor in the production and use of single-phase series core reactors. At present, the method of vibration reduction for reactor is mostly passive. In order to reduce the vibration from the root, a current conducting ring was added to the reactor pad, and the conducting ring generated damping force that canceled out the stress on the reactor core. First, the electromagnetic-mechanical coupled model of the reactor was established. The magnetic and mechanical field of the reactor were calculated based on finite element method. The vibration characteristics of the reactor with or without current rings were compared. The results showed that the vibration acceleration of the reactor was reduced by 12.95%. Finally, a vibration experiment platform of the reactor was set up, the method was verified. This study has guiding significance for the design of low vibration and noise reactor in the future.
