Abstract:
(EN) A rotor (2) has: a rotor core (21) that has a magnet insertion hole (21a) and an opening (21c); and a permanent magnet (22) that is inserted into the magnet insertion hole (21a) and that forms a first magnetic pole. When a first maximum width of the opening (21c) in a direction orthogonal to the radial direction is defined as L1 and a second maximum width of the opening (21c) in the radial direction is defined as L2, the rotor (2) satisfies L1 < L2. The distance from the opening (21c) to the magnet insertion hole (21a) is smallest at the magnetic pole center (c1) of the first magnetic pole.
(FR) Cette invention concerne un rotor (2), comprenant : un noyau de rotor (21) qui a un trou d'insertion d'aimant (21a) et une ouverture (21c) ; et un aimant permanent (22) qui est inséré dans le trou d'insertion d'aimant (21a) et qui forme un premier pôle magnétique. Lorsqu'une première largeur maximale de l'ouverture (21c) dans une direction orthogonale à la direction radiale est définie en tant que L1 et une seconde largeur maximale de l'ouverture (21c) dans la direction radiale est définie en tant que L2, le rotor (2) satisfait L1 < L2. La distance de l'ouverture (21c) au trou d'insertion d'aimant (21a) est la plus petite au centre de pôle magnétique (c1) du premier pôle magnétique.
(JA) ロータ(2)は、磁石挿入孔(21a)と開口部(21c)とを有するロータコア(21)と、磁石挿入孔(21a)に挿入されており第1の磁極を形成する永久磁石(22)とを有する。径方向と直交する方向における開口部(21c)の第1の最大幅をL1とし、径方向における開口部(21c)の第2の最大幅をL2としたとき、ロータ(2)は、L1<L2を満たす。開口部(21c)から磁石挿入孔(21a)までの距離は、第1の磁極の磁極中心(c1)で最も小さい。
