  • Electric machine with improved cooling feature
    Patent number: 6731028
    Abstract: An electric machine, includes a stator with a laminated stator body having winding end portions potted in a cast, and a rotor for interaction with the stator. In order to cope with the increased heat development in the zone of the winding end portions compared to the zone of the stator body, the cast of the winding end portions is formed with surface-enlarging structures in heat-conducting contact with a cooling jacket or with a cooling medium, and/or the cast is provided at least partially with a heat-conducting envelope which carries off heat.
    Type: Grant
    Filed: September 20, 2001
    Date of Patent: May 4, 2004
