Abstract
Studies have been carried out on an eddy-current-rail-brake for railway vehicles, which uses linear motor technology and is called “linear-rail-brake.” This brake is capable of generating braking forces without contact. In addition, this method decreases the rise in rail temperature which is a problem in conventional rail brakes, and no excitation power supply is required by using dynamic braking.
A prototype of the linear-rail-brake was designed and built. Its electromagnetic characteristic was examined on a test bench. This article reports on design considerations of the linear-rail-brake and test results of the prototype, including calculated performances by JMAG.
