Abstract
The invention relates to a magnetocaloric generator includes a set of porous active elements based of MCM materials, and a magnetic arrangement. The magnetic arrangement includes two superposed magnetic rotors, namely an external magnetic rotor and an internal magnetic rotor delimiting an air gap between them, and includes one same number of magnetic poles. The set of active elements includes a stator disposed in said air gap. The active elements extending axially in said stator enable a two-directional axial circulation of a heat-transfer fluid between a hot end and a cold end of said generator. The external magnetic rotor is advantageously coupled, on the one hand, to an electrical machine by a mechanical coupling, and on the other hand, to said internal magnetic rotor by a magnetic coupling, such that said rotors move in one same direction of rotation and are magnetically synchronous.
