Abstract (en)
An electric water pump (1) includes a pump cover (10) having an inlet (12) through which coolant flows; a stator chamber (45) having a stator generating a magnetic field according to a control signal; a rotor chamber (35) having a rotor (37) rotating according to the magnetic field generated by the stator; a separation wall (90) configured to separate the stator chamber from the rotor chamber; a shaft (100) having a central axis, fixed to the rotor so as to rotate together with the rotor about the central axis thereof; and an impeller (17) fixed to a front portion of the shaft so as to rotate together with the shaft, the impeller pressurizing a coolant having flowed in through the inlet, wherein at least one wing portion (110) is formed on a part of the shaft to increase a flow of the coolant.
