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.

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： The stator core having stator coils thereon of a submersible electric motor is provided with a cylindrical can disposed in engagement with the inner surface of the stator coil and molded resin member is formed completely about the external surface of the core, the end surfaces of the core and the end portions of the coils in engagement with the end portions of the can to completely encapsulate the core and coils. The end portions of the can may be bent outwardly and embedded directly in the molded resin member during the molding thereof with the can located within the core. Alternatively, a mold tool may be located within the core for molding the molded resin member about the stator core and coils and upon removal of the tool a hollow cylindrical can may be located within the core. The end portions of the can are then sealed to the end portions of the molded member. A terminal plate and fastener fittings may also be molded integrally into the molded member. End brackets may then be secured to opposite ends of the molded resin member. The brackets are provided with bosses which extend into the can and a seal is provided between the can and the boss. The can, in conjunction with the end brackets, define a central portion for receiving a lubricant for the bearings supporting a rotor within the can.
