Abstract
(EN)
 An electric machine provided with an annular stator installed in a housing, and a rotor arranged in the stator and rotatably supported by the housing, a plurality permanent magnets (43) being embedded in a rotor core (41) of the rotor. Embedding holes (41B), in which the permanent magnets (43) are engaged, are provided in the rotor core (41), and filling holes (48), which are continuous in the axial direction of the rotor core (41), are formed at diagonally opposite positions of the permanent magnets (43) in the embedding holes (41B).

 La présente invention concerne une machine électrique comprenant un stator annulaire installé dans un logement de stator et un rotor installé dans le stator et supporté rotatif par le logement, une pluralité d'aimants permanents (43) étant noyés dans le noyau (41) du rotor. Des trous d'insertion (41B), dans lesquels les aimants permanents (43) sont logés, sont prévus dans le noyau (41) de rotor, et des trous de remplissage (48) qui sont continus dans la direction axiale du noyau (41) de rotor sont formés à des emplacements opposés en diagonale des aimants permanents (43) dans les trous d'insertion (41B).
