Abstract
A submersible pumping system in a machine system includes a pumping element, and a drive mechanism for actuating the pumping element. The drive mechanism has an electromagnetic element with a superconducting state at or below a critical temperature. A temperature control jacket and cooling mechanism are provided to pump heat from a heat exchange cavity to cool the drive mechanism to or below a critical temperature less than an ambient temperature in a cryogenic environment.
