Controlled Thermal Expansion of Generator Stator Frames In a vertical shaft electric generator there is frequently a problem with differential thermal expansion in the stator core and stator frame. accordingly the temperatures of the stator frame and the stator core are determined from sensors distributed on the stator frame and in the stator core. The temperatures of the stator frame and core are compared, and when the temperature of the stator frame is less than the temperature core, electric power is provided to heaters spaced about the stator frame to maintain the temperature of the stator frame substantially the same as the temperature of the stator core. |
