Latest Patents
Chang holds a patent for a "System for reducing wear and improving longevity of an electric submergible pumping system." This invention features a submergible electric motor equipped with a unique rotor bearing system designed to promote the motor's longevity. The system includes an electric motor housed within a protective casing, with a stator mounted inside. A shaft is rotatably mounted within the housing, allowing for smooth rotation through an axial passage in the stator. The rotor bearing assembly, positioned between the stator and the shaft, consists of a bearing sleeve adjacent to the shaft and a main body portion that engages with the bearing sleeve. A spring mechanism, such as a wave spring, is utilized to maintain the position of the bracelet against the stator, preventing the body portion from rotating during the shaft's operation. This innovative design aims to enhance the durability and performance of electric submergible pumping systems.
