Superconducting elements are the most important part of electromechanical systems due to their operation and these systems form superconducting electrical machines. The lack of DC resistance in super conductors contributes greatly to its greater efficiency. In a superconducting machine a very high magnetic field is produced otherwise impossible in a conventional machine and is the main characteristic of the super conductors. High magnetic field results in lower engine volume and ultimately more power density.
Cryogenics are widely used in superconductors to maintain a specific temperature that is less than the ambient temperature of up to one hundred degrees, the superconducting transition temperature (Tc), where the superconductors reach zero resistance.
Synchronous superconducting AC electric machines including alternators and synchronous motors have become more common today than before.
The rotor or rotating element of the machines has an electromagnetic field winding on itself for direct current using superconductors. However, the stationary element or stator of the machines uses the same old conductors that constitute conductors of copper that undergo normal conduction.
An attempt to reduce the resistive loss of the stator conductors cools, but the loss is not permanently eliminated.
