However, traditional hydraulic generator sets face many challenges during operation, such as low heat dissipation efficiency, insufficient structural stability, and high maintenance difficulty. These problems directly affect the efficiency and lifespan of the generator set. Therefore, developing a new type of stator frame structure for hydraulic generator sets to improve its heat dissipation performance, enhance structural stability, and simplify the maintenance process has become an urgent problem in the industry.

However, this stator frame structure has problems such as low heat dissipation efficiency, insufficient structural stability, and high maintenance difficulty, which affect the efficiency and lifespan of the generator set. Therefore, a stator frame structure for a hydraulic generator set is needed. Summary of the Utility Model
