Title (EN) MAGNET-EMBEDDED MOTOR AND COMPRESSOR USING SAME
(FR) MOTEUR À AIMANT INTÉGRÉ ET COMPRESSEUR L'UTILISANT
(KO) 자석 매립형 모터 및 이를 이용한 압축기
Abstract: front page image
(EN) The present invention enables: a stage skew to be formed by stacking steel plates without making the upper side or the rear side thereof be opposite or the stage skew to be formed by stacking steel plates of which both sides can be easily distinguished, thereby reducing a cogging torque; and low-torque rippling and high efficiency to be promoted, and controllability to be improved, by reducing both a sixth-order harmonic component and a twelfth-order harmonic component of dq coordinates with respect to harmonic components. To this end, the present invention relates to a magnet-embedded motor comprising a rotor having a predetermined skew angle of θs formed between stages adjacent along the axial direction, wherein the rotor is formed by stacking a plurality of steel plates having the same shape, each steel plate has an engagement hole group including the same number of engagement holes as the number of stages, and each engagement hole forming an engagement group is formed one-by-one at a location changed by the skew angle of θs along the circumferential direction.
(FR) La présente invention permet : de former un désalignement d'étage en empilant des plaques d'acier sans amener leur côté supérieur ou leur côté arrière à être opposé ou de former un désalignement d'étage en empilant des plaques d'acier dont les deux côtés peuvent être facilement distingués, ce qui permet de réduire le couple de détente; et d'améliorer l'ondulation à faible couple et l'efficacité élevée, ainsi que d'améliorer la capacité de commande, en réduisant à la fois une composante harmonique de sixième ordre et une composante harmonique de douzième ordre de coordonnées dq par rapport aux composantes harmoniques. À cet effet, la présente invention concerne un moteur à aimant intégré comprenant un rotor ayant un angle d'inclinaison prédéterminé de θs formé entre des étages adjacents le long de la direction axiale, le rotor étant formé par empilement d'une pluralité de plaques d'acier ayant la même forme, chaque plaque d'acier comportant un groupe de trous d'engagement comprenant le même nombre de trous d'engagement que le nombre d'étages, et chaque trou d'engagement formant un groupe d'engagement est formé un à un à un emplacement modifié par l'angle d'inclinaison de θs le long de la direction circonférentielle.
(KO) 본 발명은 강판을 표리 반대로 하지 않고 적층시켜 단 스큐를 형성할 수 있게 하거나 또는 표리를 용이하게 분별할 수 있는 강판을 적층시켜 단 스큐를 형성함으로써 코깅 토크를 저감하고, 고조파 성분에 있어서의 dq 좌표의 6차 및 12차 양쪽 모두를 저감하여 저토크 리플화 및 고효율화를 도모함과 함께 제어성을 향상시킬 수 있도록 한다. 이를 위해 본 발명은 축 방향을 따라 인접하는 단의 사이에 소정의 스큐각 θs가 형성된 로터를 가지는 자석 매립형 모터로서, 로터는 동일한 형상을 갖는 다수의 강판을 적층하여 형성되며, 각 강판은 단수와 동일한 수의 체결 구멍으로 이루어지는 체결 구멍군을 가지고 있고, 체결군을 구성하는 각 체결 구멍이 1개씩 둘레 방향을 따라 스큐각 θs 변화된 위치에 형성되어 있다.
