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 material of a case. 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), an impeller(22), a driver case(50) and a driver(80). The stator generates magnetic field with a control signal, which is applied from outside. The rotor rotates with 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).
