Abstract

The invention relates to a generator and a wind generating set, the generator comprises a rotor and a stator, one of the rotor and the stator sleeves the other one, an annular air gap is formed between the rotor and the stator, and the annular air gap is provided with a maximum air gap area and a minimum air gap area which are distributed at intervals in the circumferential direction of the rotor. And the air gap value of the annular air gap in the radial direction of the rotor is gradually reduced from the maximum air gap region to the minimum air gap region. According to the generator and the wind generating set provided by the embodiment of the invention, the generator can meet the electric energy conversion requirement, the influence of the impeller on the air gap between the rotor and the stator can be weakened or avoided, and the safety performance of the generator is improved.

Description

technical field

[0001] The invention relates to the technical field of wind power, in particular to a generator and a wind power generator set. Background technique

[0002] Wind turbines can convert natural wind energy into usable electrical energy, and are widely used. Wind turbines mainly include direct-drive wind turbines and double-fed wind turbines.

[0003] The rotor of the direct-drive wind turbine is connected to the hub of the impeller, and the wind energy absorbed by the impeller will be directly transferred to the rotating shaft connected to the rotor of the generator. However, the action of the impeller in the wind shear will generate a bending moment, which acts on the rotor of the generator and will cause the rotor to deform, resulting in the reduction of the annular air gap formed by the rotor and the stator bracket. When the air gap value of the generator is equal to zero, the rotor and stator of the generator will generate friction, which will cause the r...
