Method of fabricating a wet-rotor circulator and circulator produced thereby |
摘要 |
A wet-rotor circulator in accordance with the present invention includes a drive motor coupled to the impeller of a fluid pump. The drive motor includes a rotor assembly enclosed within a fluid impermeable jacket and a stator assembly for driving the rotor. The rotor is coaxially supported within the jacket by bearings which are permanently secured in place by circumferentially crimping sections of the jacket radially inwardly to shape-lock the bearings to the jacket. The crimping takes place during an assembly step in which an applied magnetic field causes substantially instantaneous deformation of the jacket without disturbing the coaxial relationship between the rotor shaft and its support bearings.
