Title
(EN) AN ELECTRICAL MACHINE
(FR) MACHINE ÉLECTRIQUE
Abstract
(EN) An axial flux electrical machine (10) is provided. The machine (10) includes a plurality of rotors (200), each sandwiched between a respective pair of stator parts (100). The plurality of rotors (200), together with their respective stators (100), are axially-stacked to form a multistage machine. Heat exchangers (300) are provided adjacent each stator (100) to provide cooling. Each rotor disc (200) is a composite rotor disc in which permanent magnets (230) are embedded. The magnets (230) are embedded in apertures (220) through each disc (200) so that surfaces of the magnets (230) are flush with surfaces of the respective rotor disc (200).
(FR) L'invention concerne une machine (10) électrique à flux axial. La machine (10) comprend une pluralité de rotors (200), chacun pris en sandwich entre une paire correspondante de parties (100) de stator. Les rotors (200) de la pluralité, combinés avec leurs stators (100) correspondants, sont empilés dans le sens axial pour former une machine à plusieurs étages. Des échangeurs (300) thermiques sont montés à côté de chaque stator (100) pour réaliser le refroidissement. Chaque disque (200) de rotor est un disque de rotor composite dans lequel sont incorporés des aimants (230) permanents. Les aimants (230) sont incorporés dans des ouvertures (220) à travers chaque disque (200) de telle sorte que les surfaces des aimants (230) soient à fleur des surfaces du disque (200) de rotor correspondant.
