Abstract

A lightweight regenerative brake having a large braking force is provided. A regenerative brakecomprises a brake disc () and a pair of stators () to perform regenerative braking. This regenerative brake () reduces the heat generated in the brake disc (), because a part of the kinetic energy of a railway car is regenerated by generation of electricity in a tertiary circuit of the power source side when the brake is applied, and consequently the amount of energy converted into heat energy is decreased. Compared to a conventional regenerative brake, this regenerative brake () enables the disc () to be made thinner and dispenses with a cooling device such as a fan. Accordingly, a small-sizes and lightweight brake having a large braking force can be constituted using this regenerative brake ().
