Abstract:
The present invention relates to a superconducting eddy current braking system for a railroad car, which can increase the braking power of a railroad car without giving influence on a railway by comprising: a superconducting electromagnet module (110) which is placed in the lower part of a railroad car (20) in order to vertically move with respect to a conductive plate (200) placed between driving rails (10); and an elevation driving unit (120) which vertically drives the superconducting electromagnet module (110). Therefore, the superconducting eddy current braking system can perform effective braking through a strong magnetic field, can increase the braking power of the railroad car by generating large eddy current using a nonmagnetic material with excellent conductivity such as copper and aluminum, and can remove the need of an additional pore control device for controlling void between the superconducting electromagnet module and the conductive plate.
