Abstract

The invention discloses an air gap adjustment assembly method of a wind power generator. The method comprises the following steps of: (A), designing clearance fit of spigots of a seat and front and rear end covers; (B), by uniformly selecting detection points at the front and rear ends of a stator (2) and a rotor (4), measuring an air gap value between the stator and the rotor; (C), according to the air gap value, adjusting an adjusting bolt, and uniformizing an air gap; and (D), drilling conical pin holes in joints of the end covers and the seat (1), positioning by using conical pins (14), and finishing assembly. The invention also discloses a structure of the wind power generator which is assembled by using the method. The invention has the advantages that the air gap uniformity of the generator is easily, conveniently and quickly adjusted, the phenomenon of air gap non-uniformity in the machining and motor assembly process can be quickly eliminated, one-sided magnetic pull which isgenerated by air gap non-uniformity of the stator and the rotor is effectively eliminated or reduced, vibration noise and electromagnetic noise are reduced, friction between the stator and the rotor is avoided, and the operating reliability of the generator is improved.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to a wind power generator air gap adjustment assembly method and a wind power generator structure. Background technique [0002] The doubly-fed asynchronous wind generator is the mainstream type of wind power generation. The size of the air gap between the stator and the rotor is very important. It has a great impact on the performance of the motor. In order to reduce the magnetizing current and improve the power factor, the air gap should be selected smaller. , but the air gap should not be too small, otherwise it will make it difficult to manufacture the generator. [0003] The eccentricity of the air gap will cause the generator to generate unilateral magnetic pull, generate electromagnetic vibration and noise, and easily cause the stator and rotor to rub against each other. Therefore, it is very important to ensure that the stator and rotor air gap is uniform. Th...
