To reduce the possibility of an inter-phase short circuit near the rotor end of a coil type rotary machine.SOLUTION: A coil type rotary electric machine includes a rotor 10, a stator having a stator winding passing through a stator iron core, and a stationary side transmission portion 60. The rotor 10 has a rotor shaft 11 and a rotor iron core attached to the outside of the radial direction thereof, a plurality of rotor windings that penetrate the rotor iron core, and a slip ring electrically coupled to each of the rotor windings of each phase. The stationary side transmission portion 60 has a brush holder 62 for each phase that holds a brush 61 for each phase that slides with a slip ring 15 for each phase and is coupled to an external cable, and a plurality of interphase-short-circuit prevention plates 100 formed such that each of the brush holders 62 of each phase is stationery-supported so as to sandwich each of them in the axial direction, and formed so as to include the range in which the brush holders 62 of each phase are projected within the range projected in the axial direction.SELECTED DRAWING: Figure 2 【課題】巻線形回転電機の回転子端部近傍における相間短絡の可能性を低減する。【解決手段】巻線形回転電機は、回転子１０と、固定子鉄心を貫通する固定子巻線とを有する固定子と、静止側伝送部６０とを備える。回転子１０は、ロータシャフト１１と、その径方向外側に取り付けられた回転子鉄心と、回転子鉄心を貫通する複数の回転子巻線と、各相の回転子巻線とそれぞれ電気的に結合するスリップリングとを有する。静止側伝送部６０は、各相のスリップリング１５と摺動する各相のブラシ６１を保持し外部ケーブルと結合する各相のブラシホルダー６２と、各相のブラシホルダー６２のそれぞれを軸方向に挟むように静止支持され、軸方向に投影した範囲内に各相のブラシホルダー６２を投影した範囲を含むように形成された複数の相間短絡防止板１００を有する。【選択図】図２
