    • An electrical machine including a casing (1), an oil inlet hole (7), an oil passage (2), oil outlet holes (3), a stator retainer (8), a casing end cover (10), a stator iron core (5), winding coils (6), slot insulations (12) and oil-guides (4). The oil passage (2) is located inside the casing (1) and links with the oil inlet hole (7) of the casing (1) and the oil outlet holes (3) of the stator retainer (8). The oil outlet holes (3) are located above the winding coils (6) and the oil-guides (4) are located between the oil outlet holes (3) and the winding coils (6). Oil entering from the oil inlet hole (7) pours onto the winding coils (6) by the guidance of the oil-guides (4) after flowing through the oil passage (2) and flowing out of the oil outlet holes (3). The winding coils of the electrical machine can be effectively cooled and the electrical machine can achieve higher thermal durability. An oil cooling method for the electrical machine is also provided.
    • 一种电机,包括壳体(1),进油孔(7),油路(2),出油孔(3),定子保持架(8),壳体端盖(10),定子铁 (5),绕组线圈(6),槽绝缘(12)和导油器(4)。 油路(2)位于壳体(1)的内部,与壳体(1)的进油孔(7)和定子保持架(8)的排油孔(3)连结。 出油孔(3)位于绕组线圈(6)的上方,导油件(4)位于排油孔(3)和绕组线圈(6)之间。 从进油孔(7)进入的油在流经油路(2)并从出油孔(3)流出之后,通过导油件(4)的引导而在卷绕线圈(6)上倾倒。 可以有效地冷却电机的绕组线圈,并且电机可以实现更高的耐热性。 还提供了一种用于电机的油冷却方法。
