Summary:To provide a technique for effectively cooling a coil wound around a rotor core.SOLUTION: A rotor 10 comprises: a rotor core 12 which has a plurality of salient pole parts 20 protruding to the outer side in the radial direction of the rotor 10; and a plurality of coils 30 each of which is formed such that a coil wire is wound around each of the plurality of salient pole parts 20. The rotor 10 has an insulating porous layer 40 at least in a portion between a surface of each of the salient pole parts 20 and each of the coils.SELECTED DRAWING: Figure 2 【課題】ロータコアに巻装されたコイルを効果的に冷却できる技術を提供する。【解決手段】、ロータ１０の半径方向外方に向かう複数の突極部２０を備えるロータコア１２と、前記複数の突極部２０に対してコイル線が巻装されて構成される複数のコイル３０と、を備える。ロータ１０は、突極部２０の表面とコイルとの間の少なくとも一部に絶縁性多孔質層４０を備える。【選択図】図２
