INTEGRAL OPTIMIZED FLOW CHANNELS FOR FLUID-COOLED MOTORS AND GENERATORS

摘要

An electric machine is provided. The electric machine may comprise an inlet (402) and a stator fluidly coupled to the inlet (402). The stator may comprise a first cooling channel (109;210) formed in the stator with a first cross-sectional area. A second cooling channel (110;211) may be formed in the stator and have a second cross-sectional area. The first cross-sectional area may be less than the second cross-sectional area. The electric machine may also include an outlet (406) fluidly coupled to the stator. A stator assembly (100;200;300) is also provided. The stator assembly (200;300;400) may include a first channel (109;210) with a first cross-sectional area and a second channel (110;211) with a second cross-sectional area. The second cross-sectional area may be less than the first cross-sectional area.
