Abstract

resumo patente de invenção: "estator, motor e compressor". a presente invenção refere-se ao fato de que, em estatores convencionais tendo a seção de ranhura formada na superfície periférica externa de um núcleo tendo uma ranhura passante, o fluxo de fluxo magnético ser obstruído pela seção de ranhura e a eficiência do motor ser reduzida. este estator (10) compreende um núcleo anular (60) que tem uma pluralidade de seções de dentes se projetando em direção ao interior na direção radial; e isolantes (70, 80) dispostos em ambas as seções de extremidade na direção axial do núcleo (60). os isolantes (70, 80) têm seções projetadas (74, 84) que se projetam em direção ao lado de núcleo (60) a partir de cada uma das seções de extremidade externa. além disso, o núcleo (60) tem seções de ranhura (65) dispostas na superfície periférica externa de ambas as seções de extremidade na direção axial e se encaixando com as seções projetadas (74, 84). as seções de ranhura (65) não estão presentes na área inteira na direção axial do núcleo (60).patent summary: "stator, motor and compressor". The present invention relates to the fact that in conventional stators having the groove section formed on the outer peripheral surface of a core having a through groove, the magnetic flux flux is obstructed by the groove section and the motor efficiency is reduced. . This stator (10) comprises an annular core (60) having a plurality of teeth sections projecting inwardly in the radial direction; and insulators (70, 80) arranged at both end sections in the axial direction of the core (60). the insulators (70, 80) have projecting sections (74, 84) that project toward the core side (60) from each of the outer end sections. furthermore, the core (60) has groove sections (65) disposed on the outer peripheral surface of both end sections in axial direction and engaging with the projected sections (74, 84). the groove sections (65) are not present in the entire area in the axial direction of the core (60).
