A resolver according to one embodiment of the present invention comprises: a stator around which an excitation coil having at least one phase and an output coil having at least one phase are arranged; and a rotor arranged in the inner center space of the stator at a predetermined gap from the stator so as to change gap permeance from the stator while rotating around a rotational axis, wherein an area ratio (As/Ar) of the stator and the rotor satisfies mathematical formula 1 below, and thus the magnetic saturation of the resolver is prevented without increasing the size or the weight of the resolver, measurement precision is improved, and manufacturing costs are reduced. [Mathematical formula 1] 0.22 ≤ As/Ar ≤ 0.37 (Here, As is the cross sectional area of the stator and Ar is the cross sectional area of the rotor.)

    Un résolveur selon un mode de réalisation de la présente invention comprend : un stator autour duquel une bobine d'excitation ayant au moins une phase et une bobine de sortie ayant au moins une phase sont disposées ; et un rotor disposé dans l'espace central interne du stator à un intervalle prédéterminé du stator, de façon à changer la perméance d'intervalle depuis le stator tout en tournant autour d'un axe de rotation, un rapport de surface (As/Ar) du stator et du rotor satisfaisant la formule mathématique 1 ci-dessous et, ainsi, la saturation magnétique du résolveur est empêchée sans augmenter la taille ou le poids du résolveur, la précision de mesure est améliorée, et les coûts de fabrication sont réduits. [Formule mathématique 1] 0,22 ≤ As/Ar ≤ 0,37 (Ici, As est la surface de section transversale du stator et Ar est la surface de section transversale du rotor.)

    본 발명의 일 실시예에 따른 레졸버는, 적어도 1상 이상의 여자 코일과 적어도 1상 이상의 출력 코일이 배치되는 스테이터, 및 상기 스테이터와 소정 간극을 두고 상기 스테이터의 내측 중심 공간에 배치되어 회전축을 중심으로 회전하면서 상기 스테이터와의 갭 퍼미언스(gap permeance)를 변화시키는 로터를 포함하며, 상기 스테이터와 상기 로터의 면적비(As/Ar)가 아래의 수학식 1을 만족함으로써, 레졸버의 사이즈나 무게 증가 없이 레졸버의 자속 포화를 방지하고 측정 정밀도를 개선함은 물론, 제조 비용을 절감한다. [수학식 1] 0.22 ≤ As/Ar ≤ 0.37 (여기서, As는 스테이터의 단면적, Ar은 로터의 단면적)
