    • The stator core having stator coils thereon of a submersible electric motor is provided with a cylindrical can disposed in engagement with the inner surface of the stator coil and molded resin member is formed completely about the external surface of the core, the end surfaces of the core and the end portions of the coils in engagement with the end portions of the can to completely encapsulate the core and coils. The end portions of the can may be bent outwardly and embedded directly in the molded resin member during the molding thereof with the can located within the core. Alternatively, a mold tool may be located within the core for molding the molded resin member about the stator core and coils and upon removal of the tool a hollow cylindrical can may be located within the core. The end portions of the can are then sealed to the end portions of the molded member. A terminal plate and fastener fittings may also be molded integrally into the molded member. End brackets may then be secured to opposite ends of the molded resin member. The brackets are provided with bosses which extend into the can and a seal is provided between the can and the boss. The can, in conjunction with the end brackets, define a central portion for receiving a lubricant for the bearings supporting a rotor within the can.
    • 具有潜水电动机的定子线圈的定子铁芯设置有与定子线圈的内表面配合的圆筒形罐,并且模制树脂构件完全围绕芯的外表面形成,芯的端表面 并且线圈的端部与罐的端部接合以完全地包封芯和线圈。 罐的端部可以向外弯曲并且在用位于芯内的罐的模制中直接嵌入在模制树脂构件中。 或者,模具可以位于芯内,用于将模制树脂构件围绕定子芯和线圈模制,并且在移除工具时,中空圆柱形罐可以位于芯内。 然后将罐的端部密封到模制构件的端部。 端子板和紧固件配件也可以一体地模制到模制构件中。 然后,端托架可以固定到模制树脂构件的相对端。 支架设置有延伸到罐中的凸台,并且在罐和凸台之间设置有密封件。 罐与结束支架一起限定一个中心部分,用于接收支撑罐内的转子的轴承的润滑剂。
