Abstract
A generator and a wind turbine are provided. The generator includes an active cooling circuit and a passive cooling circuit, the active cooling circuit is in communication with a closed space, and the passive cooling circuit is in communication with the external environment. The active cooling circuit includes mutually communicating chambers located at two axial ends of the generator, an air gap between a rotor and a stator of the generator, and radial channels distributed along an axial direction of the generator. The active cooling circuit is provided with a cooling device in communication with the closed space, and the stator is fixed on a fixed shaft through a stator bracket. The passive cooling circuit includes a first axial channel running through the stator, a second axial channel running through the stator bracket, and an outer surface of the generator. A heat exchanger is further arranged inside the generator.
