Abstract
Provided is a brake device for a vertical axis wind turbine. The vertical axis wind turbine comprises a tower pile, on which a blade group and an outer-rotor generator are arranged. A shaft coupling is disposed between the blade group and the generator, and is respectively connected with the blade group and a rotor of the generator. The brake device comprises an annular brake disc on the shaft coupling and more than one brake unit fixed on the tower pile. Each brake unit comprises a brake and a power source for driving the brake. The brake is matched with the brake disc. When the generator needs to be braked, the brake is driven by the power source so as to tightly hold the brake disc. Then kinetic energy of the generator is consumed by the friction between the brake and the brake disc, so that the speed of the rotor of the generator is reduced. Therefore, the aim of braking the generator is achieved.
