Abstract (en)

[origin: EP1882915A1] The method involves coupling a rotor (1) with an activation motor (5) in a torque-transfer manner using a coupler (4). The rotor is rotatably supported around a rotation axis (2), and a drive motor (17) is provided for rotating the rotor. The activation motor is operated in such a manner that torque stimulations are generated in the rotor. The torque stimulations are generated so that the torque that is transferred by the activation motor on the rotor has a temporal adjustable part in addition to a temporal constant part. The temporal adjustable part is selected as harmonic function. An independent claim is also included for an activation motor for use in a measuring arrangement for measuring of vibration of a rotatable supported rotor.
