By adding the rotor wind path design on the basis of the prior art, the problem of insufficient rotor magnetic pole cooling wind power at the non-driving end of the wind generator is solved, and the cooling effect of the wind generator is improved.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a wind power generator with a rotor wind path, and belongs to the technical field of generators. Background technique [0002] At present, the common ventilation cooling methods in direct-drive wind turbines mainly include radial ventilation cooling, axial ventilation cooling and axial-radial hybrid ventilation cooling. Among them, axial-radial hybrid ventilation cooling is more commonly used in direct-drive wind turbines. Axial-radial mixed ventilation and cooling means that the cooling air has two channels, axial and radial, inside the generator. The axial channel is mainly composed of air gap, rotor poles, stator core and so on. The radial channel is mainly composed of the back air channel of the stator core and the air channel of the stator core. The cooling air enters the motor from the air inlet on the static part of the motor, passes through the axial channel and the radial air...
