Abstract
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.
