  • Rotating electrical machine
    Patent number: 10840770
    Abstract: An electrical rotating machine includes a housing which has a bearing mounted on a wall thereof. The housing also has a plurality of air inlets, a plurality of air outlets, and spokes. The spokes extend from the bearing in a radial direction of the housing to isolate the air inlets from each other in a circumferential direction of the housing. Each of the spokes is equipped with a heat sink exposed to a flow of cooling air entering the housing through the air inlet to dissipate heat, as transmitted to the spoke, thereby minimizing transfer of the heat to the bearing through the spokes.
    Type: Grant
