| Abstract |
The railway ECB(Eddy Current Brake) is used for high speed vehicle of railway like as TGV, ICE, JR-500 because it has stable braking force at high speed. But it is not effective at low speed and it is difficult to save energy due to the excitation of electro-magnet. Although ECB with permanent magnet is used for roller-coaster, it can not control 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 be changed for various braking force. It changes the flux amount from PM, then the braking force will be reduced. The brake of 800W is simulated by using the software, "Ansoft Maxwell". The characteristics of braking will be shown by the shapes of magnet, disk and various speeds. |
