Abstract[English]
Provided are a vacuum pump, a vacuum pump component, and a method for manufacturing the same, enabling effectively to heat a portion, formed of a material having low heating efficiency, in electromagnetic induction heating by electromagnetic induction heating. A vacuum pump 300 includes a casing 310, a rotor shaft 113 disposed in the casing 310, a rotor blade 102 rotatable together with the rotor shaft 113, and a heating means 340 for performing heating by electromagnetic induction by causing an alternating current to flow through a coil 342, wherein the vacuum pump 300 exhausts a gas by rotation of the rotor blade 102, and a heated portion 350 heated by the heating means 340 includes a metal plating layer 351 having magnetism.[French]
L'invention concerne une pompe à vide, un élément de pompe à vide et un procédé de fabrication de ceux-ci, permettant efficacement de chauffer une partie, formée d'un matériau ayant une faible efficacité de chauffage, dans un chauffage par induction électromagnétique par chauffage par induction électromagnétique. Une pompe à vide (300) comprend un boîtier (310), un arbre de rotor (113) disposé dans le boîtier (310), une pale de rotor (102) apte à tourner conjointement avec l'arbre de rotor (113), et un moyen de chauffage (340) pour effectuer un chauffage par induction électromagnétique en amenant un courant alternatif à circuler à travers une bobine (342), la pompe à vide (300) évacuant un gaz par rotation de la pale de rotor (102), et une partie chauffée (350) chauffée par le moyen de chauffage (340) comprend une couche de placage métallique (351) ayant un magnétisme.
