    摘要: According to one embodiment, a rotor includes a coil slot, a sub-slot, and coil airflow paths arranged in the rotor axial direction. At least one coil airflow path among the coil airflow paths includes a first wall surface disposed on a core central portion side of a cooling gas inlet portion of the coil airflow path, a second wall surface disposed on the core central portion side of an inside of the coil airflow path, and located more on the rotor radially outward side and more on a core end portion side than the first wall surface, and a third wall surface configured to connect the first wall surface and the second wall surface, the third wall surface including a surface perpendicular to a rotor radial direction.
