Title: Slim motor for canned motor pump
Inventor: EGUCHI SHINSUKE
IPC: H02K7/14
Filed: 1993-07-09
Abstract: PURPOSE:To obtain a slim motor for a canned motor pump in which a bearing effect of a rotor shaft is generated for a motor rotor and fluid frictional loss with cooling and lubricating liquid can be reduced. CONSTITUTION:A length/diameter (shape) ratio epsilon=1/D of an axial length lto a diameter D of a motor rotor 16 is set to five times or more. Thus, the rotor 16 generates a bearing effect to a rotor shaft 12 by operations of cooling and lubricating liquids which pass a passage. Accordingly, the shaft 12 is formed in a three point linkage support state and a mode shape, a rotor shaft diameter (d) is reduced, and a capacity of a bearing 14 is decreased. Further, since the rotor 16 has a slim shape of the radio #, the diameter D is reduced, a rotating peripheral speed is decelerated, and a fluid frictional loss, i.e., a bearing load of the shaft 12 is decreased. As a result, a reduction in the diameter (d) of the rotor shaft and a decrease in the capacity of the bearing 14 are further promoted.
