简介 PROBLEM TO BE SOLVED : To provide a canned motor pump forming the rotor (magnet rotor) of a motor by integrally molding a back yoke integrally joined (adhered) to permanent magnets with a resin material. SOLUTION : The back yoke 32 and rare-earth permanent magnets 34 fixed to each other and forming the rotor are integrally molded onto a rotor body and into a mold resin part. Since flat surface parts opposed to each other are formed on the inner peripheral surface of the back yoke 32, when the molding is performed, a rotation stop against the rotor body (resin portion) is formed on the back yoke 32 by the flat surface parts, and the back yoke is securely positioned at a specified position in the circumferential direction before molding.
