Title (EN) ROTATING ELECTRIC MACHINE
(FR) MACHINE ÉLECTRIQUE ROTATIVE
(JA) 回転電機
Abstract:
(EN) In this motor, a rotor is constituted by a small angle rotor portion and a large angle rotor portion having magnet end-to-end angles different from each other, said magnet end-to-end angles being a plane angle between lines connecting each of the most outer circumferential side end portions of permanent magnets facing each other and the shaft center of the rotor. The rotor is also constituted by stacking, along the shaft line, the small angle rotor portion, the large angle rotor portion, and the small angle rotor portion in this order into three layers. This prevents the permanent magnets from being demagnetized due to temperature rise and also obtains a rotating electric machine having the permanent magnets, the temperature distribution of which is lessened in a shaft line direction.
(FR) La présente invention concerne un moteur comprenant un rotor constitué d'un petit élément de rotor angulaire et d'un grand élément de rotor angulaire dont les angles de bout en bout de l'aimant diffèrent, ledit angle de bout en bout de l'aimant formant un angle plat entre les lignes rejoignant chacune des extrémités des côtés circonférentiels les plus à l'extérieur des aimants permanents se faisant face et le centre d'arbre du rotor. Le rotor est également constitué par empilement, le long de la ligne de l'arbre, du petit élément de rotor angulaire, du grand élément de rotor angulaire et du petit élément de rotor angulaire, en trois couches et dans l'ordre mentionné précédemment. Cela permet d'éviter la démagnétisation des aimants permanents entraînée par l'élévation de température, et permet également d'obtenir une machine électrique rotative dotée d'aimants permanents dont la répartition de température dans la direction en ligne de l'arbre est réduite.
(JA)  このモータでは、回転子は、対向した永久磁石のそれぞれの最外周側端部と回転子の軸心とを結ぶ線間の平面角である磁石両端角がそれぞれ異なる角小回転子部及び角大回転子部で構成され、かつ軸線に沿って角小回転子部、角大回転子部及び角小回転子部の順序で3層に積層して構成されているので、永久磁石の温度上昇による減磁を抑制し、また軸線方向の永久磁石の温度分布を小さくした回転電気を得る。
