（不凍液）が封入された構造が知られている。 Conventionally, submersible motors have a structure called a canned type, in which the outer periphery of the stator is covered with a stainless steel frame, the inner periphery of the stator is covered with a thin stainless steel can, and each frame and can are A structure is known in which the ends are connected by a collar, and water (antifreeze) is sealed in the can to lubricate the thrust bearing.

で、製造コストが高くなる欠点があつた。 However, although this type of canned motor has good electrical insulation of the stator coil, it requires a collar to seal the end of the frame and can, so the spigot fitting between the collar and the end of the frame is difficult. In addition, machining is required for the joint between the collar and the bracket, and assembly of these parts is also required.Furthermore, since the bracket is made of cast iron, it is necessary to apply a coating to prevent rust. However, the disadvantage was that the manufacturing cost was high.

性が著しく向上する効果がある。 As described above, this invention provides a stator in which the outer periphery and sides of a stator core and the periphery of the coil ends protruding laterally of the stator core are covered with a resin molded member, and the outer periphery of the stator covered with the resin molded member is covered. An inner layer jacket made of metal, an outer layer jacket made of the same resin material as the resin molded member and covering the inner layer jacket, and screws for tightening the bracket provided on the resin molded member at the end of the stator. This makes processing and assembly simple and easy, and the entire outer periphery of the stator is covered with two layers, an inner layer and an outer layer, which reliably prevents penetration of outside water. In particular, since the inner sheath is made of metal, the stator is reinforced by the inner sheath, and since the inner sheath is covered with the outer sheath, it is protected against corrosion.As a result, it is waterproof and anti-corrosive. It is reliable, has good electrical insulation, and has the effect of significantly improving reliability.

を奏する。 In addition, when the resin mold member is made of unsaturated polyester resin, low-pressure, low-temperature molding becomes possible, which not only prevents damage to the coil, but also has low shrinkage properties, which improves dimensional accuracy and improves dimensional accuracy. It has extremely practical effects when applied to.
