Abstract

MACHINE ÉLECTRIQUE TOURNANTE À AIMANTS SURFACIQUES La machine électrique tournante comprenant un stator (1c) et un rotor (2c), le rotor comprenant des pôles magnétiques formés d’aimants permanents surfaciques (21c) qui sont fixés sur un arbre (20c) du rotor. Conformément à l’invention, la machine comprend une couche de jonction frittée entre chacun des aimants permanents surfaciques et l’arbre, chaque couche de jonction frittée assurant une liaison mécanique permanente entre un aimant permanent surfacique et l’arbre et étant obtenue par une technique de frittage.
