摘要:
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.
