Ground coils installed along the entire guideway length of a magnetically levitated (Maglev) transportation system need to withstand long-term outdoor use as they are vibrated by electromagnetic forces when a vehicle passes. Verifying ground coil dynamic durability under conditions of substantial electromagnetic vibration is important for ensuring the total reliability of the Maglev system. We therefore developed an electromagnetic vibration test apparatus unavoidable for the bench test. Using this apparatus, we succeeded in evaluating the dynamic durability performance of ground coils in operation.
