  • Publication number: 20250350170
    Abstract: An electric motor assembly has a motor housing, a stator with end windings, and a rotor. A feed line for cooling fluid is formed in the motor housing and receives cooling fluid from a sump formed in the bottom of the housing cavity. A spray tube is connected to the feed line at an end face of the motor housing, and extends across the top of the end windings. A first spray tube end is secured to the housing via a connector, and a second end is secured to the housing via a tube locator disposed in a pocket of the housing. The tube locator fixes the orientation of the spray tube outlets toward the end windings. The connector may also provide the cooling fluid to a rotor supply tube, which feeds the cooling fluid into the rotor shaft cavity. All of the cooling fluid returns to the sump.
