A superconducting coil conductor composed of a plurality of strands (10) twisted together to form a cylindrical structure, each strand (10) being composed of a core (2) composed of a plurality of parallel filaments of a superconducting material, enclosed by a metal sheath (4) forming a matrix in which at least some of the filaments are embedded, and a tubular member (6) enclosing the sheath (4) so as to be in intimate electrical contact with the sheath (4) and support the core (2). The conductor is held in support plates (16) each presenting a U-shaped conductor support channel (20) spaced inwardly from an exterior surface of the support plate (16) which is in contact with the cryogen, and a conductor compression wedge (18) inserted in the channel (20) for holding the conductor in place. The solenoid coil further includes insulating members (38) interposed between the support plates (16) and projecting radially beyond the conductor support system. This coil is radially supported by a plurality of rigid radial support units (46,60) spaced apart along the circumference of the coil and located between the coil and an enclosure side wall, each support unit (46,60) including a support structure (46) having a bearing surface (50) which contacts the coil and which includes support grooves (48) receiving the coil insulating members (38). For installing the support units (46,60) at room temperature, the coil is subjected to radial inward compressive forces which are retained until the support units (46,60) have been installed, the radial forces then being removed.

Superconducting magnetic energy storage inductor and method of

A submersible electric propulsion motor includes a sealed cylindrical stator housing defining a central flow passage and a cylindrical rotor core disposed within the stator housing passage such that the stator housing encompasses the rotor core. The rotor core defines a center flow opening which communicates with inlet and outlet ends of the stator housing passage. The motor also includes a propulsion propeller having a plurality of radial blades and a central cylindrical hub. The propeller is disposed within and across the rotor core opening with its periphery being rigidly connected to the rotor core. A support structure has end portions disposed at and rigidly attached to the stator housing inlet and outlet ends, and an axial portion which extends axially through the stator housing passage and rotor core opening and is rigidly attached to the radial portions. A cylindrical bearing is disposed about the support structure axial portion within the rotor core opening between the axial portion and the propeller hub and mounts the propeller and rotor core rigidly attached thereto for rotation relative to the support structure and the stator housing. Electrical power cables emanate from the stator housing through the support structure end and axial portions to the motor exterior for connection to a source of electrical power.
