An electric motor for use in an axle assembly. An electric motor includes a stator having a stator core and a rotor adapted to rotate within the stator core about a rotor axis. The stator includes a series of conductive windings disposed about a stator core. The winding is wound in a direction substantially parallel to the rotor axis and protrudes from the first and second ends of the stator core. The stator core is formed to include a plurality of longitudinal passages arranged radially around the stator core and adapted to allow a cooling fluid to flow through the passages. The passages of the stator core extend longitudinally through the stator core and are positioned between the windings such that heat generated by the windings is transferred to the cooling fluid to remove heat from the windings. The electric motor also includes a metering ring coupled to a first end of the stator core and a discharge ring coupled to a second end of the stator core. The ring is adapted to direct a cooling fluid through the passage of the stator core to remove heat from the windings generated by operation of the electric motor.

    用在车桥组件中的电动马达。电动马达包括具有定子芯的定子和适于在定子芯内围绕转子轴线旋转的转子。定子包括围绕定子芯设置的一系列导电绕组。绕组在大体上平行于转子轴线的方向上缠绕并且从定子芯的第一端和第二端突出。定子芯被形成为包括多个纵向通路,所述通路径向围绕定子芯布置并且适于允许冷却流体流过所述通路。定子芯的通路纵向延伸穿过定子芯,并定位于绕组之间,以使得由绕组产生的热量被传递至冷却流体以从绕组中去除热量。电动马达还包括耦合至定子芯的第一端的计量环和耦合至定子芯的第二端的排放环。所述环适于引导冷却流体流过定子芯的通路,以从绕组中去除因电动马达的运行而产生的热量。
