We provide the measurement data and the values for the FEM model. We start by the describtion of the measurement data. The measurement data has the following strcture: The .mat file contains 2 variables: targeted and data_messung - targeted only contains the meta data of the measurements which we aimed for (start/end rotor speed, measurement time, etc.) - data_messung contains the measurement data The data is listed in the matrix data_messung.data. Note that we use the coordinates y and z in the publication. The test-rig uses the coordinates x and y instead. We use the convention of the paper here. Furthmore, note the following: In the publication, positive frequencies correspond to the forward whirl. However, the rotor on the test-rig rotates into the negative x-direction. This causes negative frequencies to correspond to the forward whirl when combining the data r = rx +i*ry! The second plane was not actively used in the experiments (no power amplifiers installed). The realtime system still generates the voltages internally e.g. the 500 V offset. However, you can ignore all corresponding voltages and currents for the second active plane. In the publication, we only use the data of Disc 1, Bearing 1 and the actuators of Bearing 1. We will, however, also provide the measurement data for the remaining Disc and Bearing. Note that the passive measurement and the system identification measurements recorded different signals which we will specify afterwards. The columns correspond to the following data (Control experiments (Figure 3)): 1. Rotor speed; Differentiation of the current angle with and an additional moving average for smoothing which causes a time delay. Unit is in rpm. We used an offline filter to estimate the current rotor speed for the publications which negates this time delay 2.

Time of the realtime system in seconds ============================================================================================================== =================================== FEM model data =========================================================== ============================================================================================================== We included the FEM model data for the four transfer functions between actuator voltage and the displacements of Disc 1, Disc 2 as wells as the forces in Bearing 1, Bearing 2. The data fields correspond to the following: .rotor_speed: Rotor speed in Hz (absolute value) .excitation_frequency: Excitation frequency of the bearing plane which corresponds which is equal to the rotor speed. We defined it positive here in accordance with the publication. This frequency is negative on the test-rig since the rotor rotates into the negative x-direction (-\overline(Omega) t) .Hf1: Transfer function between (complex) actuator voltages and (complex) bearing forces in Bearing 1 (shown in publication) .Hf2: Transfer function between (complex) actuator voltages and (complex) bearing forces in Bearing 2 .Hr1: Transfer function between (complex) actuator voltages and (complex) displacements of Disc 1 (shown in publication) .Hr2: Transfer function between (complex) actuator voltages and (complex) displacements of Disc 2
