The utility model relates to a motor stator concave slot wedge, and belongs to the technical field of motor manufacturing. The utility model mainly solves the technical problems of unequal slot fullness, poor heat dissipation performance of the winding, poor integrity of the winding in the slot and the like in the prior art. According to the technical scheme adopted by the utility model, the top surface of the slot wedge is provided with a groove, the width B of the slot wedge is 0.7 mm smaller than the size of a slot shoulder of a stator punching sheet, and the included angle alpha between slopes on the two sides of the top of the slot wedge and the horizontal plane is consistent with the angle of a slot opening of the stator punching sheet; the width B1 of the groove is the same as the width of the notch of the stator punching sheet, and the distance h between the bottom surface of the groove and the bottom surface of the groove wedge is 1.5-2 mm. The device has the advantages of being simple in structure,
