    摘要: In an encased electric motor within a casing, an electrically insulating varnish is applied by vacuum impregnation to the inside surfaces of the casing and to the outer surface of the stator of the motor. The remaining empty space within the casing is filled with a heat conducting gas mixture comprising approximately 60-90% by volume of helium, with the remaining percentage being an electrically insulating gas having better electrically insulating properties than helium, such as sulphur hexafluoride. This encased motor is much lighter than conventional encased motors in which the stator enclosure is filled with a heat conducting resin potting compound and avoids warping damage which frequently occurs in conventional encased motors due to thermal expansion of the heat conducting resin potting compound.

    摘要: A submerged electric motor comprises an outer hollow cylinder formed of a stainless steel, a stator iron core fixed on the inside of the outer cylinder, an annular end plate of a general structural rolled steel welded to an annular end portion formed between the outer hollow cylinder and an inner hollow cylinder coaxial with it by using a welding wire of the stainless steel. A combined deposit metal and fused portion underlaid with the end plate is machined to have an end surface flush with that of the end plate. A bracket is fixed to those end surfaces through bolts. Also a sheet-shaped soft sealing member may be interposed between the bracket and the machined end plate.
