Abstract
Systems and methods for producing hydrocarbons from a subterranean well include an electrical submersible pump assembly with a motor. The motor has a motor housing and a stator is located within the motor housing. The stator has a stator body with an interior cavity. A rotor assembly is located within the interior cavity of the stator. The rotor assembly includes a rotor shaft, a rotor member, and an intermediate rotor bearing assembly. The rotor member and the intermediate rotor bearing assembly circumscribe the rotor shaft. The rotor shaft extends along the central axis of the stator. A liner is located along an interior surface of the interior cavity, the liner being a thin walled member that is secured to the motor housing and seals the stator body from a wellbore fluid. The liner has a polygonal cross section.
