Summary:To provide a stator in which eddy-current loss that occurs in a rectangular coil can be reduced.SOLUTION: A stator 1 comprises stator cores 10 having a plurality of slots 12 each open in an inner peripheral surface 11 and a plurality of teeth 13 each formed between the slots 12 adjacent to each other, and rectangular coils 20 wound around the teeth 13 respectively. The rectangular coil 20 has a penetration hole portion 26 penetrating from an inner surface 27 of the rectangular coil 20 opposing the inner peripheral surface 11 up to an outer surface 28 of the rectangular coil 20 opposing an outer peripheral surface 18 of the stator core 10.SELECTED DRAWING: Figure 1 【課題】平角コイルで発生する渦電流損を低減することができる固定子を提供する。【解決手段】内周面１１に開口する複数のスロット１２と、互いに隣接するスロット１２の間に形成された複数のティース１３とを有する固定子鉄心１０と、ティース１３のそれぞれに巻回された平角コイル２０とを備えた固定子１において、平角コイル２０は、内周面１１に対向する平角コイル２０の内側面２７から固定子鉄心１０の外周面１８に対向する平角コイル２０の外側面２８まで貫通した貫通孔部２６を有する。【選択図】図１
