METHOD FOR MANUFACTURING STATOR FOR ELECTRIC WATER PUMP
First Claim
1. A method for manufacturing a stator assembly for an electric water pump, wherein the stator assembly including a plurality of core-insulator assemblies generates a magnetic field according to a control signal and a rotor is rotated by the magnetic field generated at the stator assembly to pressurize coolant, the method for manufacturing the stator assembly comprising:
- a) stacking a plurality of pieces made of a magnetic material to form a core stack;
b) molding an insulator to the core stack;
c) coiling a coil to the insulator to form a core-insulator assembly so as to form a magnetic path; and
d) connecting the respective core-insulator assembly in an annular shape in sequence to form the stator assembly.
