A synchronous electric machine (8) includes a machine housing (26) including a stator (27) and a rotor (28) disposed in the stator, the rotor being separated from the stator by an air gap (29), the machine housing being configured to dissipate heat loss generated by the stator. The stator comprises: a stack (30) of laminated structures (300) and at least one channel (36) extending in a longitudinal direction of the stator and formed in the laminated structures, two adjacent stacks of laminated structures being separated by a pin or spacer (31) to form an extraction duct (32) connected to the channel, the machine housing further comprising an extraction opening (21), the fluid injected into the air gap at the end of the stator flows in the extraction duct and in the channel, and is extracted from the machine through the opening to cool the stator and the rotor.
同步电机器(8)包括机器壳体(26),机器壳体(26)包括:定子(27)和安置在定子中的转子(28),转子与定子被气隙(29)隔开,机器壳体构造成消散由定子产生的热损失。定子包括:层压结构(300)的堆叠(30)和沿定子的纵向方向延伸并在层压结构中形成的至少一个通道(36),两个相邻层压结构堆叠由销或间隔件(31)隔开以形成连接到通道的提取管道(32),机器壳体进一步包括提取开口(21),使得在定子的端部处气隙中注入的流体在提取管道中和在通道中流动,并且通过开口从机器中提取以冷却定子和转子。
