Analyse électromagnétique d'une source de champ magnétique multipolaire pour un système de froid magnétique.

Electromagnetic analysis of a multipole field source for a magnetic refrigeration system.

Résumé

In this paper, several configurations of a rotary magnetic refrigerator are proposed and investigated using three dimensional finite element method simulations. Their electromagnetic performance is analyzed considering the magnetic flux density, the forces and the torque. The rotor is a single permanent magnet while the stator is made of four refrigerant beds and a magnetic yoke. Multipole stators or rotors with 4, 6 and 8 refrigerant beds have been tested. The beds can be fitted or set at the inner surface of the yoke. The yoke can have smooth or salient poles. To minimize the magnetic torque, an original structure is proposed and tested. It is composed of two half-systems assembled with a 45° angle shift between rotors or stators. Because of the large amount of data, a suitable procedure to achieve an effective comparison between all configurations is established.
