COUPLING AN ELECTRIC MACHINE AND FLUID-END

摘要

A submersible fluid system for operating submerged in a body of water includes a fluid-end that has a fluid rotor disposed in a fluid-end housing. An electric machine housing is coupled to the fluid-end housing and includes a hermetically sealed cavity. An electric machine, such as a motor and/or generator, is disposed entirely within the cavity of the electric machine housing. The electric machine includes an electric machine stator and an electric machine rotor. A magnetic coupling couples the electric machine rotor and the fluid rotor.
