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： A submerged electric motor has a molded bracket fitted into a hollow cylindrical molded member for a canned stator to cause an annular sealing member to abut against a radial front end surface connected to a cylindrical surface abutting against that of the molded member and another cylindrical surface connected to the front end surface on the bracket side and against an axial extension of the abutting cylindrical surface and a radial bottom surface connected to each other on the molded member side while a can disposed on the inner surface of the molded member has an extension radially outward bent so as to be sandwiched between the sealing member and the bottom surface.

摘要： A motor of the submersible type drives a pump immersible in liquids. The motor is provided with guide grooves formed on the motor bracket for guiding undesirable small particles falling by gravity onto the bracket away from the area near the motor shaft so that before an overabundance of undesirable small particles accumulates on a collar mounted on the motor shaft, the accumulated particles gravity fall into the guide grooves. By this arrangement the undersirable wear of the motor shaft and oil seals located between the motor shaft and the motor bracket is eliminated.
