Abstract

The invention discloses a novel generator. The novel generator comprises a fixed base and a rotating shaft rotationally installed on the fixed base, wherein a plurality of guide pins are integrally and vertically installed on the fixed base, a plurality of positioning pins are integrally and vertically installed on the rotating shaft, the guide pins and the positioning pins are parallel to the axis of the rotating shaft, the positioning pins are sleeved with a plurality of rotors coaxially arranged with the rotating shaft, the guide pins are sleeved with a plurality of stators coaxially arranged with the rotating shaft, the plurality of rotors and the plurality of stators are sequentially and alternately arranged along a vertical direction, each stator comprises an upper wall and a lower wall which are oppositely distributed along a vertical direction, an inserting groove is formed between each upper wall and the corresponding lower wall, and a plurality of coils are detachably mounted at the peripheral circle of eachinserting groove. An assembling method of the novel generator comprises the following steps: installation of the rotating shaft, installation of each single rotor, installation of each single stator, stacking of the stators and the rotors, and installation of the coils. According to the invention, the assembling efficiency of the generator can be improved, the impregnation efficiency of the coils can be improved, and impregnation cost can be reduced.

Description

Technical field[0001]The present invention relates to the technical field of generator devices, and in particular to a new type of generator and a assembly method thereof.Background technique[0002]Permanent magnet synchronous generators are mainly composed of components such as rotors, end caps and stars. The stator structure of the permanent magnet synchronous motor is very similar to the structure of the ordinary induction motor, and the maximum difference between the rotor structure and the asynchronous motor is placed on the rotor with high quality permanent magnet magnets, depending on the position of the permanent magnets on the rotor. Permanent magnet synchronous motors are typically divided into surface rotor structures and built-in rotor structures.[0003]The current permanent magnet synchronous generator has the following flaws:[0004](1) Existing permanent magnet synchronous generators generally use modular assembly methods, assembly process is extremely complex, and genera...

Problems solved by technology

[0004] (1) Existing permanent magnet synchronous generators generally adopt a modular assembly method, and the assembly process is extremely complicated. It usually includes the following steps. First, the rotor is positioned on the shaft, and then the stator wound with coils is installed on the rotor. On one side, one-to-one correspondence, the modularized rotor and stator are very difficult in the process of handling and installation, and the positioning accuracy is not high; when the stator or its upper coil fails, it is generally necessary to repair the entire stator Replacement requires a large amount of work and high cost;

[0005] (2) In addition, the coils in the generator need to be impregnated with resin. This step is generally carried out in vacuum impregnated substations. Due to the large volume of the stator wound with coils, it is difficult to fully impregnate the coils, which affects the coil treatment effect of the generator.
