Superconductor Electromagnets:

 

The field-wound superconductor electromagnet synchronous electric machine system (EMS) improves efficiency and physical size by increasing air-gap flux density beyond the conventional EMS; but the cryogenic support equipment significantly complicates and significantly negates the cost, power density, and efficiency of the superconductor EMS as clearly demonstrated by the unavailability of a practical superconductor EMS even after decades of well-funded research.

 

 

NOTE: All electric machines require a multiphase AC stator armature that is virtually the same amongst any EMS, including the superconductor EMS, but a superconductor multiphase AC stator armature is impractical with present superconductor technology.[1]

 

 

NOTE: Without giving details at this time, SYNCHRO-SYM EMS technology with brushless real time control (BRTC) can bring superconductor electric machine systems closer to practical reality. For instance, BRTC provides pure sinusoidal excitation (without harmonic content) to mitigate quenching and shielding of the superconductor field windings; and can brushlessly relocate the superconductor field winding to the stator to at least relieve rotating mechanical stress on the cryogenic field winding with simple structural support, all of which eliminate the complexity, maintenance, reliability, and cost issues associated with a rotating hydraulic interface for the low temperature cryogenics.

 

 


[1] The alternating current (AC) stator armature effectively represents the major proportion of loss, size, and cost of any electric machine system with the DC field winding (or electromagnet) of ,  synchronous EMS showing nearly zero loss in proportion. For every unit of loss associated with a superconductor, at least 100 to 1000 fold of cryogenic refrigeration capacity (with its own associated loss, size, and cost) is needed for cooling and as a result, only a powerful superconductor direct current (DC) electromagnet (expected for electric machines) is seemingly practical.
