A stator winding heat dissipation structure for unmanned aerial vehicle driving motors is provided. One side of each U-shaped heat pipe is located in a stator slot of a motor, and is an evaporation section. The bottom and the other side of each U-shaped heat pipe extend out of the motor, and are a condensation section. There is a liquid working medium in the heat pipes. One side of each U-shaped heat pipe is evenly arranged between the copper wires of stator windings in the stator slots along the slotting direction, and is in close contact with the copper wires. Multiple U-shaped heat pipes are arranged at the two ends of the motor. Two sides of one pair of U-shaped heat pipes are opposite, and are arranged towards the two end faces along the axial direction from the middle position of a stator slot. The condensation sections of one pair of U-shaped heat pipes extend out of the motor. Another axially adjacent pair of U-shaped heat pipes is also arranged in this way. The condensation sections of the U-shaped h
