摘要： A direction in which cooling air generated by a cooling fan flows to be discharged is perpendicular or nearly perpendicular to a direction in which diffusers are inclined. Thus, airflow resistance is increased by the diffusers, and the cooling air cannot be efficiently discharged from discharge ports provided circumferentially in an outer peripheral portion of a housing. Further, a stator coil cannot be sufficiently cooled. An electrical rotating machine includes: a rotor having a cooling fan on an end face of the rotor; a stator that is arranged opposite the rotor and has a stator coil with a rotation clearance provided between the stator and the rotor; a housing that holds the rotor and the stator; a plurality of intake ports that are provided in a side wall portion of the housing; a plurality of discharge ports that are provided circumferentially in an outer peripheral portion of the housing; and a plurality of diffusers that are provided circumferentially on an inner wall surface of a corner portion of the housing, the diffusers inclining toward the side opposite to a rotational direction of the rotor.
摘要翻译：由冷却风扇产生的冷却空气流动排出的方向与扩散器倾斜的方向垂直或几乎垂直。因此，通过扩散器增加了通气阻力，并且冷却空气不能从壳体的外周部分周向设置的排出口有效地排出。此外，定子线圈不能充分冷却。旋转电机包括：转子，其在转子的端面上具有冷却风扇; 定子，其与所述转子相对配置并具有设置在所述定子和所述转子之间的具有旋转间隙的定子线圈; 保持转子和定子的壳体; 多个进气口，设置在壳体的侧壁部分中; 多个排出口，其设置在所述壳体的外周部的圆周方向上; 以及在壳体的角部的内壁面周向设置的多个扩散器，扩散器向与转子的旋转方向相反的一侧倾斜。
