Abstract: The disclosure relates to a generator and a wind turbine. The generator includes an active cooling loop and a passive cooling loop that are isolated from each other and both are in communication with external environment. The active cooling loop includes cavities that are in communication with each other and located at two respective ends of the generator in an axial direction, an air gap between a rotor and a stator of the generator, and radial channels arranged at intervals and distributed along the axial direction of the stator. A cooling device in communication with the external environment is disposed in the active cooling loop. The passive cooling loop includes an axial channel extending through the stator in the axial direction and an outer surface of the generator.

Abstract: The present application relates to a slot wedge element, a stator device, a motor, and a wind turbine. The slot wedge element extends in a first direction and has opposite first and second edges has a first surface and a second surface in the thickness direction thereof, and is attached to a winding of the stator device via the first surface. The second surface includes a first portion, a second portion, and a third portion sequentially distributed in the first direction. A second thickness between the second portion and the first surface is greater than a first thickness between the first portion and the first surface, and the second thickness is greater than or equal to a third thickness between the third portion and the first surface. The first thickness is decreasingly distributed in a direction from the second portion to the first edge.

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.
