ータの提供をその目的とする。[Detailed Description of the Invention] The present invention relates to a canned motor for use in submersible pumps, etc. In induction motors used underwater, such as submersible pumps, the stator windings are molded with resin and hermetically sealed using can seals, but cage-type rotors do not have windings, so sealing has not been a problem in the past. . However, many of the recent cage-shaped rotors are made of aluminum die-casting, and after long-term use underwater, there is a risk that they will corrode and become unusable. From this point of view, the present invention relates to a sealed structure of a cage rotor and aims to provide a canned motor that can withstand long-term operation.

It is sealed and fixed. This excitation of stator A causes rotor B to rotate. Reference numeral 3 denotes a cage-shaped rotor core, and the aluminum casting portion 4 forms a cage-shaped winding. 5 is a rotor groove. Reference numeral 6 denotes a hollow cylindrical cover made of a corrosion-resistant metal plate such as a thin stainless steel plate fitted around the outer periphery of the rotor B, and has openings 61 at both ends,
Side lids 7, 7 made of stainless steel plates are fitted into the interior of the housing 61. When the side covers 7, 7 are inserted through the shaft 8 of the rotor B and the flat parts of the side covers 7, 7 are brought into close contact with both sides of the rotor B with the cover 6 attached as shown, both ends of the cover 6 are opened. The outer peripheral edges 71, 71 of the side lids 7, 7 fit into the inner peripheries of the parts 61, 61 and overlap, and the ear piece 9 is formed by the peripheral edges of the openings 61, 61 at both ends of the cover and the outer peripheral edge of the side lid 7. It is formed. By performing TIG welding (tungsten inert gas welding) along the edge of the lug 9, the rotor B is sealed and formed into a water-resistant structure. Note that C is the motor jacket.

がある。 As described above, in the present invention, a stator is formed by molding synthetic resin to seal and fix the winding part, and a hollow cylinder made of a thin stainless steel plate is attached to the outer periphery of a cage-shaped rotor that rotates when excited by the stator. The cover is inserted and the stainless steel side covers that can be fitted into the openings at both ends of the cover are inserted through the shaft of the rotor, and the flat parts are brought into close contact with both sides of the rotor, so the structure is simple, lightweight, and complete. A corrosion-resistant rotor outer cover can be formed, making assembly easy. Sealing ears are formed by the openings at both ends of the cover and the outer periphery of the side lids fitted into the inner peripheral surfaces of the openings at both ends of the cover. It has the advantage of increasing the overall sealing effect with a limited welding area.
