Title (EN) PERMANENT MAGNET, ROTARY ELECTRICAL MACHINE, AND VEHICLE
(FR) AIMANT PERMANENT, MACHINE ÉLECTRIQUE ROTATIVE ET VÉHICULE
Abstract:
(EN) The permanent magnet includes: a main phase expressed by a composition formula: RMZNX and having at least one crystal structure selected from the group consisting of a Th2Ni17 crystal structure, a Th2Zn17 crystal structure, and a TbCu7 crystal structure; and a sub phase having a phosphorus compound phase containing a phosphorus compound excluding a phosphoric acid compound.
(FR) L’invention concerne un aimant permanent comprenant : une phase principale exprimée par une formule de composition : RMZNX et ayant au moins une structure cristalline choisie dans le groupe constitué par une structure cristalline Th2Ni17, une structure cristalline Th2Zn17, et une structure cristalline TbCu7 ; et une sous-phase ayant une phase de composé de phosphore contenant un composé de phosphore à l'exclusion d'un composé d'acide phosphorique.
