A lightweight regenerative brake having a large braking force is provided. A regenerative brake 1 comprises a brake disc (10) and a pair of stators (20) to perform regenerative braking. This regenerative brake (1) reduces the heat generated in the brake disc (10), 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 (1) enables the disc (10) 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 (1).
A regenerative brake comprising a brake disc attached to an axle of a wheel of a railway car and a stator for braking provided in a position facing to a disc surface of the brake disc, wherein
