17. A method comprising:
disposing a turbine into a wellbore, wherein the turbine comprises:
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;
an gap that separates the stator and the rotor;
one or more blades disposed on the outer housing between the turbine housing and the rotor;
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, and
compressing the compressible medium with the one or more magnets when an electromagnetic field from the stator increases in strength from a short in one or more armature coils disposed on the stator.
