[0002] As the core component of a wind turbine, the wind turbine pitch system is mainly responsible for dynamically adjusting the pitch angle of the wind turbine blades. Its goal is to ensure the power balance of the wind turbine above the rated wind speed, and to ensure the overall safety of the wind turbine through aerodynamic braking under extreme weather conditions. Through pitch control, the system can effectively adjust the angle of attack of the wind turbine blades to adapt to the working requirements under different wind speeds, thereby achieving efficient and stable wind power generation.

[0003] The existing pitch cabinet needs to control the pitch motor, and the pitch cabinet is often fixedly connected to the hub of the wind turbine, and the hub needs to rotate.
