The invention provides a motor stator assembly structure and a cooling system thereof. The stator assembly mainly comprises flow-guiding pipe assemblies (3), a stator core (7) and windings (8); the cooling system of the stator assembly mainly comprises an oil inlet (1), the flow-guiding pipe assemblies (3), an oil outlet (10), an oil storage device (12), a filtering device (13) and a cooling oil radiating device (14); the flow-guiding pipe assemblies (3) are assembled in yoke through holes of the stator core (7); the stator assembly is matched with end covers (4 and 11) on the two sides through the flow-guiding pipe assemblies (3) so as to ensure positioning; the cooling mode of the cooling system is an oil cooling mode in which the windings (8) are directly sprinkled. In the technical scheme provided by the invention, efficient cooling of a power motor system is achieved, the effective radial size of a motor is ensured to the maximum extent, and the power density and the torque density of the motor are enhan
