Free QuoteAlthough much research has been conducted in terms of the qualitative and quantitative analysis of AC loss and its reduction methods, AC loss remains a crucial problem for the design of highly efficient superconducting machines, especially for those operating at high speeds for future aviation.
AC Loss Measurement Approaches There exist three main approaches for measuring the AC loss of superconductors, namely, electric, magnetic, and calorimetric methods [ 131 ]. 5.1. Electric Method The electric method is extensively used on account of its fast measurement speed and high sensitivity.
In addition to the modifications to the physical structure of HTS CCs, the application of magnetic materials as flux diverters in electrical machines can also serve to decrease the AC loss of superconductors.
The alternating current (AC) loss of superconductors caused by time-varying transport currents or magnetic fields (or both) has impaired the efficiency and reliability of superconducting machines, bringing severe challenges to the cryogenic systems, too.
AC loss is generated by the movement of magnetic vortices within the superconductor when experiencing time-varying currents or magnetic fields [ 16 ]. Inside electric machines, the electromagnetic environment is complicated, composed of abundant AC electromagnetic signals and high-frequency harmonics, especially for high-speed rotating machines.
Scientists have found the first material that displays a much sought-after property at room temperature. It is superconducting, which means electrical current flows through it with perfect efficiency - with no energy wasted as heat. At the moment, a lot of the energy we produce is lost as heat because of electrical resistance.
