Critical-current reduction in thin superconducting wires due to current crowding

Optimization of an HTS Induction/Synchronous Motor According to Changing of HTS Tapes Critical Current by Analytical Hierarchy Process

This paper represents the performance of a squirrel-cage High Temperature Superconducting Induction/ Synchronous Motor (HTS-ISM) based on nonlinear electrical equivalent circuit. The structure of the HTS-ISM is the same as that of the squirrel-cage type induction machine, and the secondary windings are fabricated by the use of the HTS wires. It has already been shown that based on the experimen...

Current Degradation and Coupling Losses in Ring Shaped Wires due to Applied Magnetic Field Changes

AbstmctThe stationary electric field and current distribution in a ring shaped wire subject to both parallel and perpendicular applied magnetic fields is calculated. The time derivative of the parallel field is limited for the centre of the wire to be unsaturated. The transient response of an infinitely long wire due to a parallel applied magnetic field BA shows that BA itself is limited for th...

The degradation of the critical current density in a Nb3Sn tape conductor due to parallel and transversal strain

In order to investigate the influence of mechanical strain on the intrinsic critical current density, a tape conductor is selected as a simple two-dimensional model. In a tape geometry a homogeneous strain distribution can be generated with an external load. A new experimental setup is designed to maintain two different components of the strain tensor (transverse and axial) in a superconducting...
