Abstract:
(EN) Provided is a dynamo-electric machine with which it is possible to reduce cogging torque. Each tooth facing part 14 has a high-magnetic-resistance part. Teeth include first teeth 10a in which the high-magnetic-resistance part 11, 11A is disposed on one circumferential side of the circumferential center of a tooth base part 13, and second teeth 10b in which the high-magnetic-resistance part 11, 11A is disposed on the other circumferential side of the circumferential center of the tooth base part 13. Each of the high-magnetic-resistance parts 11, 11A is such that the circumferential center of the high-magnetic-resistance part 11, 11A is disposed on the tooth-base-part 13 side of straight lines that link the center of rotation of a rotor 3 and the circumferential-direction-side end parts 24a, 24b of a boundary part 24 between the tooth facing part 14 and the tooth base part 13.
(FR) L'invention concerne une machine dynamo-électrique permettant de réduire le couple de saillance. Chaque partie face de dent (14) comporte une partie à résistance magnétique élevée. Les dents comprennent des premières dents (10a) dans lesquelles la partie à résistance magnétique élevée (11, 11A) est disposée sur un côté circonférentiel du centre circonférentiel d'une partie de base de dent (13), et des secondes dents (10b) dans lesquelles la partie à résistance magnétique élevée (11, 11A) est disposée sur l'autre côté circonférentiel du centre circonférentiel de la partie de base de dent (13). Chacune des parties à résistance magnétique élevée (11, 11A) est conçue de sorte que le centre circonférentiel de la partie à résistance magnétique élevée (11, 11A) est disposé sur le côté partie de base de dent (13) de lignes droites qui relient le centre de rotation d'un rotor (3) et les parties d'extrémité côté direction circonférentielle (24a, 24b) d'une partie de limite (24) entre la partie face de dent (14) et la partie de base de dent (13).
(JA) コギングトルクを低減することができる回転電機を提供する。 各ティース対向部14は、高磁気抵抗部を有し、各ティースは、高磁気抵抗部11、11Aがティース基部13の周方向の中心より周方向の一方側に配置された第1のティース10aと、高磁気抵抗部11、11Aがティース基部13の周方向の中心より周方向の他方側に配置された第2のティース10bとを含み、各高磁気抵抗部11、11Aは、高磁気抵抗部11、11Aの周方向における中心がロータ3の回転中心と、ティース対向部14とティース基部13との境界部24における周方向側の端部24a、24bとを結ぶ直線よりもティース基部13側に配置されている。
