Abstract: Provided is an electric water pump with an over-molding stator for improving a flow structure and a dimensional accuracy in the water pump. The pump largely includes: a stator including a rotor accommodation part accommodating a rotor and a plurality of coils arranged around a rotating shaft of the rotor in a circumferential direction; and a molding part surrounding the stator to insulate the plurality of coils, wherein the molding part is injected onto the stator to surround the entire coil while having a plurality of flow paths formed between the coils and passing through in a direction of the rotating shaft.

Abstract: The present disclosure relates to a water pump in which a channel is formed so that a fluid introduced through an inlet side passes through a bearing part and a channel inside the rotor accommodation part and the rotor is formed so that the fluid may circulate, so a lubricating action of a bearing rotatably coupled to the rotor is smoothed and a pressure difference between upper and lower sides of an assembly of the rotor and an impeller assembly is reduced, thereby reducing abnormal noise and vibration in the bearing part.
