Abstract: By simplifying the structure of the 3 MW induction generator, the fluid-solid coupled model of 3D temperature field and fluid field for stator and rotor is built; the numerical simulation of temperature field and fluid field distribution for stator and rotor is done by using the finite volume method on Fluent simulation software platform based on hydromechanics theory. The proposed method can not only provide certain reference for studying temperature field of the generator, but also provide a theory gist for structure optimization and ventilation design of the generator.
