The principle of operation of the Superconducting Generators/Motors is the same as that for conventional electric machines such as synchronous permanent magnet generators/motors and induction machines. However, superconducting windings can be exploited to provide a more powerful magnetic field than conventional copper coils.
Adoption of superconducting coil in rotating machines can provide high efficiency, more compact and more environment-friendly electric power applications.

Coil cover: Supports the superconducting coil against the centrifugal force
Cooling chamber: Ultra low temperature cooling unit
Core: Non-magnetic composite stator core
Damper: Protects the superconducting coil from the high frequency magnetic field
Rotary seal: Rotary room to supply the ultra low temperature coolant
Shield: Shields the magnetic field from leakage to the surroundings
Slip ring: Applies current to the superconducting coil
Stator coil: Stator coil (copper)
Superconducting coil: Coil made of superconducting material
Vacuum jacket: Forms the vacuum insulation layer
Torque tube: Insulating structure

Doosan have collaborated on the development of the technology for superconducting generators/motors with KERI (Korea Electric Research Institute), which has one of the most advanced technologies in the superconducting power system field in Korea.
