Abstract
Systems and methods for providing power to a device of a downhole tool within a subterranean well during production operations include an energy harvesting system located within a tubular. The energy harvesting system has a turbine assembly with a turbine rotary member rotating relative to a turbine housing. A turbine magnetic array has a plurality of turbine magnets arranged in a ring shape. A power generator assembly has an input shaft assembly operable to provide a rotational energy to a power generator. A generator magnetic array of the input shaft assembly has a plurality of generator magnets arranged in a ring shape. A turbine sleeve surrounds the input shaft assembly, and forms a sealed barrier between the input shaft assembly and the turbine assembly. The turbine sleeve is formed entirely of a non-magnetic material.
