  • Cooling assembly for electric machine
    Patent number: 7402924
    Abstract: A cooling assembly including a generally cylindrical body to be inserted inside the generally cylindrical internal stator of an electric machine is described herein. The body includes a cylindrical external contact surface configured and sized to contact the internal surface of the stator. The bottom surface of the body is machine with a channel that is partially closed by a cover to yield a peripheral fluid passage inside the body. An inlet and an outlet aperture are provided.
