【発明の詳細な説明】
この発明は井戸内等で使用されるモールド型水中モード
ルの改良に関するものである。以下、この発明の一実施
例について説明する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a molded underwater model used in wells and the like. An embodiment of the present invention will be described below.

樹脂からなるレジンモールド部材ｚ７はねじ金である。In FIG. 1, reference numeral 1 denotes a stator consisting of a stator core 2 and a stator coil, and a thin stainless steel can 8 is inserted into the inner periphery of the stator core 2. As shown in FIG. Reference numeral 4 denotes a resin mold member z7 made of unsaturated polyester resin that surrounds the outer periphery and sides of the stator core 2 and the coil end 5 of the stator coil, and is a screw metal.

される。8 is a rotor, 9 is a rotor shaft, and 10 is a bracket, which supports the rotor shaft 9 through a bearing 11. 12 is a bolt that is tightened. Reference numeral 18 denotes a powder coating applied around the coil end 5 using polyethylene or polypropylene. After forming this powder coating layer, the entire coil end is molded with the resin mold member 4.
