Electric Water Pump
First Claim
1. An electric water pump apparatus including:
- a stator generating a magnetic field according to a control signal;
a rotor enclosed by the stator and rotated by the magnetic field generated at the stator;
a pump cover having an inlet through which coolant flows in and an outlet through which pressurized coolant flows out;
a body having;
a front surface forming a volute chamber between the pump cover and the front surface;
a stator chamber formed at an outer portion of the body in a radial direction, wherein the stator is mounted in the stator chamber; and
a rotor chamber formed at an inner portion of the body in a radial direction, wherein the rotor is mounted in the rotor chamber;
a shaft having a central axis, fixed to the rotor so as to rotate together with the rotor about the central axis thereof, and mounted in the rotor chamber; and
an impeller fixed to a front portion of the shaft so as to rotate together with the shaft, pressurizing the coolant having flowed in through the inlet, and mounted in the volute chamber.
