“…Under certain conditions, a superconductor can be used to trap a magnetic field, but also as a field shielding device to guide the magnetic field lines. The material is then used, no longer to channel the magnetic field as one usually did with the ferromagnetic materials, but to deviate it is the diamagnetic effect screen effect to create a new structure of a flux barrier superconducting machine [19][20][21][22][23].…”

Numerical tools appear to be essential for modeling and designing devices based on superconducting materials. In this article different simulation results are presented, using a computer code based on the finite element method adopted for the resolution of the electromagnetic equations, in the case of an axisymmetric two-dimensional problem, with this code we study the variations of the different electromagnetic quantities. The second generation superconductor has been modeled as an interesting diamagnetic material as inductive pulse sources. The performance in magnetic field resistance, energy storage and thermal stability of the ribbon, known as YBCO, makes it possible to broaden its field of application. Two categories of machines have been proposed and analyzed, the first is classic and the second uses a superconducting ribbon. In addition, a comparative study between the two proposed models is carried out and the results are analyzed and discussed.

“…Thus, the power has been increased to 66% compared to the single superconducting inductor. El Hassan et al [ 18 , 19 ] installed a circular screen bulk between the two solenoids in a way to be in an inclined position. This prototype resembles the engine of the claw pole in its operating principle.…”

Design Development and Analysis of a Partially Superconducting Axial Flux Motor Using YBCO Bulks

In this work, authors have designed, constructed and tested a new kind of partially superconducting axial flux machine. This model is based on the magnetic flux concentration principle. The magnetic field creation part consists of the NbTi superconducting solenoid and two YBaCuO plates. A theoretical study is conducted of an extrapolated superconducting inductor for low-temperature superconducting and high-temperature superconducting solenoids. The optimization of the inductor is carried out in order to increase the torque and the power density as well. This improvement is done by changing the shape of the elements which form the superconducting inductor. Finally, a prototype is realized, and tested.

“…By adding an external three-phase armature, we obtain a 2-pole synchronous machine (Fig.1.c). This machine can be seen as a claw pole type synchronous machines which can develop a high electromagnetic torque due to the increase in the level of flux density in the air gap [6]. This is the structure, with complex geometry, that we propose to model with the meshed reluctance network approach.…”

“…The principle is based on the modulation of the magnetic field obtained by the exciting coils using superconducting screens [3]- [5]. High air-gap flux density values are achieved which result in compact machines suitable in marine, wind turbine and aircraft industries [2], [3]- [6]. The design of such superconducting machines requires the study of highly non-linear magnetic field diffusion in superconducting materials (excitation coils and screen).…”

-In this paper a new superconducting inductor topology intended for synchronous machine is presented. The studied machine has a standard 3-phase armature and a new kind of 2-poles inductor (claw-pole structure) excited by two coaxial superconducting coils. The air-gap spatial variation of the radial flux density is obtained by inserting a superconducting bulk which deviates the magnetic field due to the coils. The complex geometry of this inductor usually needs 3D finite elements (FEM) for its analysis. However, to avoid a long computational time inherent to 3D FEM, we propose in this work an alternative modeling which uses a 3D meshed reluctance network. The results obtained with the developed model are compared to 3D FEM computations as well as to measurements carried out on a laboratory prototype. Finally, a 3D FEM study of the shielding properties of the superconducting screen demonstrates the suitability of using a diamagnetic-like model of the superconducting screen.
