Abstract
A stator liquid cooling structure and a stator structure of a stator yokeless disc motor are provided. The cooling structure includes an annular stator bracket and a water jacket. An outer periphery of the stator bracket is in a groove structure and is fixedly connected with the water jacket. Opposite upper and lower ends of the water jacket are provided with a liquid inlet and a liquid outlet. The stator structure includes stator cores, an armature winding, the stator bracket and the water jacket. A first stator core and a second stator core of the stator cores are same in structure and oppositely arranged. The armature winding is wound on first stator tooth bodies and second stator tooth bodies of the stator cores; the first stator tooth bodies and the second stator tooth bodies are inserted into gaps between adjacent blade-shaped cavities and fixed on the stator bracket.
