View the Complete Application at the US Patent & Trademark Office
A downhole system for use in a wellbore in a subterranean formation includes an electromechanical motor or generator. The electromechanical motor or generator may, respectively, be configured convert electricity to mechanical energy or convert mechanical energy in the form of fluid flow for use in one or more downhole tools. The electromechanical motor or generator includes one of a rotor and a stator disposed concentrically around and operatively coupled to the other of the rotor and the stator. A sleeve is disposed concentrically between the rotor and the stator. The sleeve contacts a body to enclose and hermetically seal one of the rotor and the stator therein. The sleeve comprises at least one metal portion and at least one non-magnetic and non-conductive portion. Related methods involve the formation of such a motor or generator.
