Abstract
A downhole turbine may include a stator disposed in a turbine housing, a rotor disposed between the stator and the turbine housing and wherein the rotor includes an outer housing, a gap that separates the stator and the rotor, wherein the gap is oil filled, and one or more blades disposed on the outer housing between the turbine housing and the rotor. The downhole turbine may further include a compressible medium attached to the outer housing between the stator and the outer housing, wherein the compressible medium is separated from the stator by the gap, and one or more magnets attached to an inner surface of the compressible medium, wherein the one or more magnets are separated from the stator by the gap.
