摘要: An electric machine includes a stator, a rotor configured to rotate about an axis, and a housing surrounding the rotor and the stator. The housing includes an end cap at an axial end of the electric machine. The housing encloses an end space between the rotor and the end cap. The electric machine also includes a nozzle disposed within the end space and configured to discharge a cooling fluid into the end space in a direction tangential to the rotation of the rotor. The cooling fluid may include liquid, such as oil. The electric machine may be an induction machine or a synchronous machine. The nozzle may include an inlet tube that extends through the end cap. The electric machine may include two end spaces on opposite ends of the rotor, with one or more nozzles located in each of the two end spaces.
