Summary:PROBLEM TO BE SOLVED: To provide a pump capable of enhancing motor efficiency while having a structure resistant to water contact to a yoke. SOLUTION: The pump 1 is equipped with a pump case 3 which includes a pump chamber 5 thereinside and openings of a suction port 9 and delivery port 11 communicating to the pump chamber 5, an impeller 19 arranged in the pump chamber 5, and a motor 21 consisting of a cylindrical rotor magnet 27a mounted in the impeller 19 to rotate integrally therewith, and a cylindrical stator 23 fixed to the pump case 3 and provided concentrically with the rotor magnet 27a. At least inner and outer peripheral surfaces contain yokes 27b embedded in the rotor magnet 27a. COPYRIGHT: (C)2009,JPO&INPIT
