Abstract
(EN) The purpose of the present invention is to secure creepage insulation distance and to increase insulation reliability. The present invention comprises: a stator core formed of a cylindrical body, accommodation spaces for accommodating a plurality of segment coils being formed along the axial direction of the cylindrical body on the inner peripheral side of the cylindrical body, and the accommodation spaces being multiply formed on the inner peripheral side of the cylindrical body with gaps maintained therebetween; and a plurality of coil support members constituted as annular members, the coil support members supporting the segment coils, each coil support member having a plurality of through holes for inserting the segment coils, the through holes being openings connected to the accommodation spaces, and each coil support member being disposed separated to either end part in the axial direction of the stator core, and covering the inner peripheral side of the end parts in the axial direction of the stator core.
(FR) Le but de l'invention est de sécuriser la distance d'isolation d'une fuite et d'augmenter la fiabilité d'isolation. Le dispositif de l'invention comprend : un noyau de stator formé d'un corps cylindrique; des espaces de logement pour loger une pluralité de bobines de segment formées le long de l'axe du corps cylindrique sur le côté périphérique intérieur du corps cylindrique, les espaces de logement étant multipliés sur le côté périphérique intérieur du corps cylindrique avec des espaces maintenus entre eux; et une pluralité d'éléments de support de bobines constitués en éléments annulaires et servant de support aux bobines de segment. Chaque élément de support de bobines comporte une pluralité de trous traversants pour l'insertion des bobines de segment, les trous traversants étant des ouvertures reliées aux espaces de logement; et chaque élément de support de bobines est disposé séparé de chaque partie d'extrémité dans la direction axiale du noyau de stator, et recouvre le côté périphérique intérieur des parties d'extrémité dans la direction axiale du noyau de stator.
(JA) 本課題は、沿面絶縁距離を確保し、絶縁信頼性を高めることである。 筒体で形成され、筒体の内周側に、複数のセグメントコイルを収納するための収納空間が、筒体の軸方向に沿って形成されると共に、収納空間が筒体の内周側に互いに間隔を保って複数個形成される固定子鉄心と、環状の部材として構成され、複数のセグメントコイルを支持する複数のコイル支持部材と、を備え、各コイル支持部材は、各収納空間に連なる開口であって、セグメントコイルを挿入するための複数の貫通孔を有し、且つ固定子鉄心の軸方向両端部に分かれて配置されて、固定子鉄心の軸方向端部の内周側を覆う。
