Abstract (en)

[origin: EP1914387A1] The turbo machine has a rotor (2) and a shaft sealing, which is designed as a dry gas seal. A turning device (60) is provided in a turbo machine strand. The turning device is designed in such a manner that the turning of the rotor takes place at a rotational speed of less than 10 revolutions/minute, preferably less than 1 revolution/minute. The turning device has a motor (61), where a gear is provided between the motor and the rotor. An independent claim is also included for a method for turning a rotor of a turbo machine.
