Abstract
An electric water pump may include a stator generating a magnetic field according to a control signal and a rotor rotated by the magnetic field generated at the stator and pressurizing coolant. According to the electric water pump, the stator may include, a stator core formed by stacking a plurality of pieces made of a magnetic material, an insulator connecting pieces of the stator core to each other, a coil coiling the stator core so as to form a magnetic path, a Hall sensor detecting a position of the rotor, a Hall sensor board controlling the control signal supplied to the stator according to the position of the rotor detected by the Hall sensor, and a stator case wrapping and sealing the stator core, the insulator, the coil, the Hall sensor, and the Hall sensor board.
