Abstract:
The present invention relates to the arrangement of a stator and a spare stator. In order to avoid a permanent correction in the length of the driving shaft, the spare stator is connected to the instantaneously operated stator or is configured in a single piece. Upon occurrence of a defined amount of wear, this stator combination is merely reversed through 180° relative to the longitudinal axis or an intermediate tube is inserted so that the spare stator arrives in the rotor region.
