ELECTRIC WATER PUMP

摘要

PURPOSE: An electrical water pump is provided to increase operation performance and durability since a stator and a rotor, which electrically operate, are covered with a resin case with a waterproof function. CONSTITUTION: An electrical water pump comprises stators(102,104,108,109), rotors(84,86,88,90), a pump cover(10), a body(30), a shaft(83) and an impeller(22). The stator generates magnetic field with a control signal supplied from outside. The rotor rotates by the magnetic field generated by the stator. The pump cover comprises an entrance(12) and an exit(14). The body comprises a front side(32), a stator chamber(42), and a rotor chamber(38). The stator chamber is formed on an external circumferential part. The rotor chamber is formed on the inner circumferential part of the stator chamber and holds the rotor. The shaft comprises a central axis(x). The shaft rotates on the central axis along with the rotor.
