“…A lot of superconducting inductors using superconducting wires or bulks have been designed and tested. So, many experimental and modeling studies have shown the ability of the superconductor materials to be used as a field inductor for synchronous motors [1][2][3][4][5].…”

In this paper, we present a new kind of superconducting inductor for a synchronous machine. This inductor is composed of two superconducting coils (solenoids) having the same axis and fed by the same current. A superconducting bulk is used to obtain a variation of the flux density in the air-gap. This superconducting bulk is surrounded by a ferromagnetic material in order to improve the distribution of the radial component of the flux density. With the studied inductor, we obtain a two-pole synchronous machine having a high magnetic field value in the air-gap. The main objective of this paper is to show the feasibility of this new concept of inductor.

“…Pour ces raisons, ils ont pour avantages de permettre de construire des machines électriques plus légères avec un meilleur rendement que les moteurs classiques. Il est aussi possible de se servir des matériaux supraconducteur sous forme massive pour blinder le champ magnétique ou concentrer les lignes de flux [1,2,3,5,6,7].…”

International audienceIn this paper, we present a new kind of superconducting inductor for the synchronous machine. This inductor is composed of a two superconducting coils having the same axis and fed by a currents with the same direction. A superconducting bulk is used in order to achieve a variation of the flux density in the air-gap. The superconducting bulk is surrounded by a ferromagnetic material in order to improve the radial component of the flux density in the air-gap. With the proposed superconducting inductor, we obtain a two-poles electrical machine with an important value of a magnetic field in the air-gap

“…Indeed, during the shielding process a superconducting pellet naturally creates eddy currents inside the materiel in opposition with the change of the external magnetic field. This behavior of bulk is useful within the framework of electrical motors [1][2][3][4][5]. The kind of motor using these HTS screens developed in our laboratory is based on the concentration of magnetic flux between HTS screens.…”

International audienceHTS bulks present a high critical current density which can be used as magnetic shields. Previous works showed that BSCCO bulks can screen magnetic fields up to 0.1 T. For large scale applications like electrical machines, stronger magnetic field is usually needed. In so doing, (RE)BCO materials are more suitable since they can shield much higher magnetic fields. Another key issue concerns the size of the bulks. Nowadays, it is possible to manufacture 150-mm diameter class cylindrical YBCO bulk. In order to get larger magnetic shielding areas, multiple bulk superconductors should be arrayed and stacked in layers. This paper presents experimental results on screening performances of layered YBCO pellets. These results are compared with 2D simulations. The experiments are carried out at 77 K under external magnetic fields of 150 mT. Different topologies are considered: single-layer configuration with 9 square pellets and double-layer configuration with respectively 9 and 4 square pellets. Experimental and simulation results show that a checkerboard of one layer configuration does not fully shield the external magnetic field. Improved shielding properties are obtained when the double-layer configuration is used
