This invention relates to the field of motor technology and discloses a motor with direct oil-injection cooling function, including a motor housing and a stator core fixed inside the motor housing. The stator core includes a left tail ring, multiple left rings, multiple middle rings, multiple right rings, and a right tail ring coaxially stacked from left to right. Oil forms a three-dimensional flow network inside the stator core, covering the entire internal space of the core. During the flow of oil through the bottom arc groove, the left straight cylindrical mesh channel, the right straight cylindrical mesh channel, and the axial straight groove, the oil directly contacts the stator core, absorbing the heat generated by the stator windings and the core. The heat is rapidly carried away, avoiding the formation of localized hot spots and achieving direct and efficient cooling of the heat source core. The oil, after absorbing heat, is discharged from the oil outlet holes of the left and right tail rings and returns to the external cooling system for circulation cooling. The design of the oil outlet holes ensures smooth oil flow and prevents oil accumulation.
