Abstract

The invention relates to the technical field of power generation, in particular to a device with a stator and a rotor and a wind generating set. A device having the stator and the rotor comprises thestator, the rotor, wherein an air gap is formed between the rotor and the stator; an air gap protection device which is fixedly connected with the stator, wherein the radial distance between the air gap protection device and the rotor is smaller than that between the stator and the rotor; and the air gap protection device rotates relative to the rotor when being in contact with the rotor. The airgap protection device fixedly connected with the stator is arranged. When the rotor is contacted with the rotor., the device can rotate relative to the rotor. The radial distance between the air gap protection device and the rotor is smaller than the radial distance between the stator and the rotor; in the relative rotation process of the stator and the rotor, if the radial distance between the rotor and the stator is reduced, it can be guaranteed that the air gap protection device makes contact with the stator firstly, the stator and the rotor cannot make contact, bore sweeping is avoided, and it is guaranteed that the device with the stator and the rotor cannot be damaged.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a device with a stator and a rotor and a wind power generating set. Background technique [0002] Generator air gap refers to the gap between the generator stator and rotor. If the generator air gap is too large, the magnetic field induction between the stator and rotor will be weaker, and the efficiency of the generator will be reduced; if the generator air gap is too large Small, because the generator vibrates or the load is uneven, the rotor is eccentric during rotation, and it is easy to sweep the bore and cause damage to the generator. Therefore, controlling the air gap to a reasonable value is a necessary condition to ensure the normal operation of the generator. [0003] The prior art discloses a generator air gap real-time measurement and control device and a wind power generating unit. The air gap real-time measurement and control device is provided with a plur...
