Abstract: front page image
(EN) The present invention relates to a permanent magnet electrical equipment and, more particularly, to a permanent magnet electrical equipment having, for the purpose of reducing torque ripple, non-uniform pole pitch angles and pole number and slot combinations therefor. Further, according to the present invention, provided is a permanent magnet electrical equipment comprising: a rotor comprising first magnetic poles and second magnetic poles arranged alternately with a rotor core, wherein the pole pitch angle of the first magnetic poles and the pole pitch angle of the second magnetic poles are different from each other; and a stator comprising a stator core, teeth disposed at regular intervals on the inner side of the stator core along the circumferential direction of the stator core, and phase winding wires wound around each tooth, the stator supporting the rotator to be rotatable. Accordingly, the present invention has non-uniform pole pitch angles and a pole number and slot combinations therefor, thereby being capable of reducing torque ripple.
(FR) La présente invention porte sur un équipement électrique à aimant permanent et, plus particulièrement, sur un équipement électrique à aimant permanent qui possède, dans le but de réduire l'ondulation de couple, des angles de pas polaire non uniformes et un nombre de pôles et des combinaisons de fentes correspondants. En outre, l'équipement électrique à aimant permanent est pourvu : d'un rotor comprenant des premiers et seconds pôles magnétiques agencés en alternance avec un noyau de rotor, l'angle de pas polaire des premiers pôles magnétiques et l'angle de pas polaire des seconds pôles magnétiques étant différents l'un de l'autre ; d'un stator comprenant un noyau de stator, des dents disposées à intervalles réguliers sur le côté interne du noyau de stator dans la direction circonférentielle du noyau de stator, et des fils d'enroulement de phase enroulés autour de chaque dent, le stator soutenant le rotor de façon à pouvoir tourner. Par conséquent, la présente invention possède des angles de pas polaire non uniformes et un nombre de pôles et des combinaisons de fentes correspondants, ce qui permet de réduire l'ondulation de couple.
(KO) 본 발명은 영구 자석 전기기기에 관한 것으로, 특히, 토크 맥동 저감을 위해 비균일한 극호각과 이를 위한 극수 슬롯 조합을 갖는 영구 자석 전기기기에 관한 것이다. 또한, 본 발명에 따르면, 회전자 코어와 교대로 배치되는 제1 자극들 및 제2 자극들을 포함하고 있으며, 상기 제1 자극의 극호각과 제2 자극의 극호각이 상이한 회전자; 및 고정자 코어와, 상기 고정자 코어의 내측에는 그 둘레방향을 따라 일정한 간격을 두고 배치되어 있는 치형들과 각 치형에 권선되는 상권선들을 가지며, 상기 회전자를 회전가능하게 지지하는 고정자를 포함하는 영구자석 전기기기가 제공되어 비균일한 극호각과 이를 위한 극수 슬롯 조합을 갖고 있어 토크 맥동을 저감시킬 수 있다.
