Abstract

An embodiment of the invention provides a stator of a generator. The stator of the generator includes a plurality of stator units, each stator unit includes an iron core module and a winding arranged on the iron core module, the iron core module includes a stator iron core which has a yoke part and at least one tooth part fixedly arranged on the yoke part, each tooth part is provided with a winding in one-to-one correspondence, the yoke is provided with grooves along an axial direction of the stator, fixed keys are arranged inside the grooves, and mounting holes are arranged on the fixed keys. The fixed keys at the bottom of the yoke of the stator can realize fixed connection with a support, thereby enabling manufacture to be relatively simple, and effectively reducing cost.

Description

technical field [0001] The invention relates to generator technology, in particular to a generator stator. Background technique [0002] With the gradual increase of the single-unit capacity of wind turbines, the diameter of direct-drive permanent magnet wind turbines is getting larger and larger, not only the requirements for processing equipment are also getting higher and higher, and the transportation costs increase accordingly, and land transportation cannot be realized. At the same time, there are still some problems in the generator stator in the prior art. [0003] Such as figure 1 As shown, the stator 1' of the distributed generator in the prior art is an integral circular ring structure, which is formed by stacking sheets, embedding wires and dipping paint on the support 2'. For large-scale direct drive wind turbines, the diameter of the stator 1' is generally more than 4 meters. The conventional integral stator 1' needs a special large dipping equipment for the ...
