摘要： A stator structure is provided and includes a plurality of first lamination layers, a plurality of second lamination layers, two third lamination layers and two oil spraying rings. The second lamination layers are sandwiched in between the first lamination layers. The second lamination layer located in the middle of the stator structure is sandwiched in between the two third lamination layers. The two oil spraying rings are connected to two first lamination layers located at outermost sides. Another stator structure is provided and includes a plurality of first lamination layers, a second lamination layer and two oil spraying rings. The second lamination layer is sandwiched in between two first lamination layers. The two oil spraying rings are connected to two first lamination layers located at outermost sides. By means of the arrangement of the aforesaid stator structure, the invention can effectively improve heat dissipating effect for oil cooling.
