Abstract (en)

[origin: EP2009286A1] The seal has a magnetic bearing rotor and a magnetic bearing stator, where the seal is implemented as a magnetic bearing (19) for sealing a rotor (9) of a turbomachine e.g. single shaft-turbo compressor (1). The magnetic bearing is controllable in such a manner that active forces are applied on the rotor by the magnetic bearing. The magnetic bearing rotor and the magnetic bearing stator are implemented in the form of a labyrinth, a hole pattern seal, a honeycomb or a smooth slot. The bearing stator is mounted at a housing of the turbomachine.
