要約
(EN) A rotor comprising: a rotor core that has an outer periphery extending in a circumferential direction about an axis, and has a magnet insertion hole extending along the outer periphery; and a permanent magnet disposed in the magnet insertion hole. The rotor core has a plurality of slits formed on the radially outer side of the magnet insertion hole about the axis, and a bridge extending so as to connect the radially inner side and the radially outer side of the magnet insertion hole. The plurality of slits include a first slit that is closest to the end part of the magnet insertion hole in the circumferential direction, and a second slit that is closest to the bridge. The relationship R1 > T1 holds true, where T1 is the shortest distance from the magnet insertion hole to the first slit, and R1 is the shortest distance from a reference point to the second slit, the reference point being a point positioned at the center of the bridge in the circumferential direction on a straight line that defines the end edge on the radially outer side of the magnet insertion hole.
(FR) La présente invention concerne un rotor qui comprend : un noyau de rotor qui a une périphérie externe s'étendant dans une direction circonférentielle autour d'un axe, et un trou d'insertion d'aimant s'étendant le long de la périphérie externe ; et un aimant permanent disposé dans le trou d'insertion d'aimant. Le noyau de rotor a une pluralité de fentes formées sur le côté radialement externe du trou d'insertion d'aimant autour de l'axe, et un pont s'étendant de manière à relier le côté radialement interne et le côté radialement externe du trou d'insertion d'aimant. La pluralité de fentes comprend une première fente qui est la plus proche de la partie d'extrémité du trou d'insertion d'aimant dans la direction circonférentielle, et une seconde fente qui est la plus proche du pont. La relation R1 > T1 s'applique, T1 étant la distance la plus courte du trou d'insertion d'aimant à la première fente, et R1 étant la distance la plus courte d'un point de référence à la seconde fente, le point de référence étant un point positionné au centre du pont dans la direction circonférentielle sur une ligne droite qui définit le bord d'extrémité sur le côté radialement extérieur du trou d'insertion d'aimant.
(JA) ロータは、軸線を中心とする周方向に延在する外周を有し、外周に沿って磁石挿入孔を有するロータコアと、磁石挿入孔に配置された永久磁石とを備える。ロータコアは、磁石挿入孔に対して軸線を中心とする径方向の外側に形成された複数のスリットと、磁石挿入孔の径方向の内側と外側とを結ぶように延在するブリッジとを有する。複数のスリットは、磁石挿入孔の周方向の端部に最も近い第1のスリットと、ブリッジに最も近い第2のスリットとを有する。磁石挿入孔から第1のスリットまでの最短距離をT1とし、磁石挿入孔の径方向の外側の端縁を規定する直線上でブリッジの周方向の中心に位置する点を基準点とし、基準点から第2のスリットまでの最短距離をR1とすると、R1>T1が成り立つ。
