영구자석을 이용한 Shield moving형 와전류 제동기의 철도시스템 적용연구

초록

The railway ECB(Eddy Current Brake) is used for high speed vehicle of railway like as TGV, ICE, JR-500because it has stable braking force at high speed. But it is not effective at low speed and it is difficult to save energydue to the excitation of electro-magnet. Although ECB with permanent magnet is used for roller-coaster, it can notcontrol the braking force without clutch. In this paper, the shield moving ECB with PM is proposed for application of railway vehicle. The angle of shield can bechanged for various braking force. It changes the flux amount from PM, then the braking force will be reduced. Thebrake of 800W is simulated by using the software, “Ansoft Maxwell”. The characteristics of braking will be shown bythe shapes of magnet, disk and various speeds.
