  • Air cooled electric motor
    Patent number: 9391493
    Abstract: An electric machine includes a stator having a first end and a second end and an end frame including a first cup portion arranged to at least partially contain a portion of the stator. The end frame is positioned adjacent the first end of the stator. A potting cup includes a second cup portion arranged to at least partially contain a portion of the stator. The potting cup is positioned adjacent the second end of the stator. A potting member is coupled to the stator, the end frame, and the potting cup to permanently bond the end frame, the potting cup, and the stator to one another.

  • AIR COOLED ELECTRIC MOTOR
    Publication number: 20130342051
    Abstract: An electric motor assembly. A stator includes a set of windings and has a first end, a second end, and an outer radial surface. A rotor includes a shaft having an axis. A first frame supports the shaft at a first axial position. A canopy substantially surrounds the first frame. The canopy includes a fluid inlet and a fluid discharge. A second frame supports the shaft at a second axial position and includes at least one fluid outlet. A chute is positioned downstream of the canopy fluid discharge. The chute directs fluid flow along the outer radial surface of the stator towards the fluid outlet. A fan is coupled to the shaft downstream of the fluid outlet for rotation with the shaft.
