    摘要: In a submersible motor, a liquid is filled into its rotor chamber, a shaft to which a rotor is fixed is supported on a frame by sleeve bearings, and a diaphragm for controlling the pressure within the rotor chamber is disposed at the lower portion of the frame. Chambers communicating with the rotor chamber, are disposed above an upper sleeve bearing and the chambers accomodate a reserve liquid having a volume larger than that of the diaphragm. Therefor, even if the pressure within the rotor chamber rises and the diaphragm is deformed, the upper sleeve bearing is continuously filled with the liquid, thereby enabling continuous lubrication and cooling.
