<p><P>PROBLEM TO BE SOLVED: To provide an electric water pump, improved in operational performance and durability. <P>SOLUTION: The electric water pump includes: a stator for generating magnetic field according to a control signal applied from the external; and a rotor rotated by the magnetic field generated by the stator to supply cooling water. The stator includes a stator core 102 formed by stacking a plurality of magnetic body pieces; an insulator 104 connecting the plurality of magnetic body pieces; a coil 108 generating magnetic field to surround the stator core 102; a Hall sensor 112 for sensing the position of the rotor; a Hall sensor substrate 110 for controlling a control signal applied to the stator according to the position of the rotor sensed by the Hall sensor 112; and a stator case 109 for surrounding the stator core 102, the insulator 104, the coil 108, the Hall sensor 112 and the Hall sensor substrate 110 and sealing the same. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
