Abstract

PROBLEM TO BE SOLVED: To select a new specification without being influenced by design changes by forming an impeller formed in such a constitution that a ring base plate of the impeller is formed integratedly with an end part of a rotor, a ring shroud plate on which a plurality of blades are implanted is formed independently from the ring base plate, and they are connected and fixed to each other. SOLUTION: The rotor 13 of a circulating pump is formed so as to hold permanent magnets 13-1 which are uniformly arranged on an outer periphery and bearings 13-2 which are arranged on an inner circumferential surface, and also an ring base plate 6-1 for forming an impeller is formed integratedly with an end part of a holding member 13-3. In the ring base plate 6-1, a blade is not arranged, and a blade 6-3 is implanted on a shroud plate 6-2 which is arranged opposing to the ring base plate 6-1. The blade 6-3 is held between the ring base plate 6-1 and the shroud plate 6-2 so as to integrate with each other, and thereby, the impeller of a closed type is constituted. It is thus possible to select a new specification without being influenced by design changes, when the specification of the rotor or the impeller is changed.
