Title (EN) SYNCHRONOUS RELUCTANCE TYPE ROTARY ELECTRIC MACHINE
(FR) MACHINE ÉLECTRIQUE ROTATIVE À RÉLUCTANCE SYNCHRONE
(JA) 同期リラクタンス型回転電機
Abstract: front page image
(EN) A synchronous reluctance type rotary electric machine according to one embodiment of the present invention has a rotor iron core. The rotor iron core has a plurality of poles, wherein a plurality of layers of cavities, each having have a shape projected radially inside each pole, are formed, and a bridge is formed between the cavities and the outer peripheral surface. When a boundary between two adjacent poles is set as a pole boundary, a groove is formed on at least one of the two sides flanking the pole boundary therebetween, at a position avoiding the pole boundary in the outer peripheral surface of the rotor iron core.
(FR) La présente invention concerne une machine électrique rotative à réluctance synchrone qui, selon un mode de réalisation, comporte un noyau de fer de rotor. Le noyau de fer de rotor comporte une pluralité de pôles, une pluralité de couches de cavités ayant chacune une forme projetée radialement à l'intérieur de chaque pôle, étant formées, et un pont étant formé entre les cavités et la surface périphérique externe. Lorsqu'une limite entre deux pôles adjacents est définie en tant que limite de pôle, une rainure est formée sur au moins l'un des deux côtés qui encadrent la limite de pôle entre eux, dans une position évitant la limite de pôle dans la surface périphérique externe du noyau de fer de rotor.
(JA) 実施形態の同期リラクタンス型回転電機は、回転子鉄心を持つ。回転子鉄心は、複数極有し、1極当りに径方向内側に向かって凸形状となる空洞部が複数層形成されていると共に、空洞部と外周面との間に、それぞれブリッジが形成されている。そして、隣接する2つの極の間の境界を極境界としたとき、回転子鉄心の外周面には、極境界上を避けた位置で、且つ極境界を挟んで両側の少なくとも何れか一方に、溝部が形成されている。
