[0030] The implementation principle of the new energy vehicle electronic water pump system in Embodiment 1 of the present application is that if greater water pressure is needed, the output voltage can be increased by the transformer 12, the voltage of the winding coil is increased, the magnetic field intensity generated by the winding coil is increased, and the rotating speed of the rotor is increased.
