  • Stator of a cryogenic electric machine
    Patent number: 4398108
    Abstract: The annular cavity in the stator of a cryogenic electric machine is defined by the housing and by the cylindrical element holding the winding. An electrically non-conducting ferromagnetic liquid is introduced into the annular cavity and is permitted to flow therein. The ferromagnetic liquid also serves as a cooling liquid for the cryogenic electric machine. A cooling system is connected to the annular cavity and together they form a closed loop for the circulation of the ferromagnetic liquid. Axial ribs are provided on the inner surface of the housing to prevent rotation of the ferromagnetic liquid as it flows inside the annular cavity.
