It belongs to the field of electronic water pump technology in new energy vehicles. Background Technology

[0002] New energy vehicles typically have two or more electronic water pumps. These electronic water pumps are the power source for the entire cooling system of new energy vehicles. The power battery, drive motor, and other components of new energy vehicles all rely on the electronic water pumps to drive the coolant for circulation and cooling.

[0003] Existing electronic water pumps typically include a top cover, pump casing, middle casing, shaft core, rotor assembly, stator assembly, circuit board assembly, etc. The top cover, pump casing, and middle casing are combined and fixed together to form a chamber. The two ends of the shaft core are fixed to the top cover and the pump casing, respectively. The rotor assembly is supported by the shaft core in the chamber between the top cover and the pump casing. The stator assembly is located outside the chamber and can magnetically drive the rotor assembly to rotate in the chamber between the top cover and the pump casing, thereby driving the water flow through the impeller on the rotor assembly, so that the water flows in a directional manner.
