Zusammenfassung:An electric motor includes a case, a stator that includes end-windings, a rotor coupled to the case via rotor bearings. The rotor includes a hollow cylindrical body, a first shaft portion, and a second shaft portion. The hollow cylindrical body includes an inner wall, an outer wall, a first distal end, and a second distal end. The first shaft portions couples to the first distal end and the secondshaft portion couples to the second distal end. The second shaft portion includes a fluid feed tube formed therewith having a fluid receive end and a fluid feed end, the fluid feed end extending to acentral inner portion of the hollow cylindrical body. A plurality of fluid exit ports adjacent to the first distal end and the second distal end of the hollow cylindrical body spray fluid onto at least the end-windings of the stator when the rotor is rotating. 种电动机,包括壳体、包括端部绕组的定子、经由转子轴承耦合到壳体的转子。转子包括中空柱形本体、第轴部分和第二轴部分。中空柱形本体包括内壁、外壁、第远端以及第二远端。第轴部分耦合到第远端,而第二轴部分耦合到第二远端。第二轴部分包括与其起形成的流体供给管,该流体供给管具有流体接收端和流体供给端,该流体供给端延伸到中空柱形本体的中心内
