Description
Total Rotor Runout Dataset
Data of tactile multi-probe and eddy current displacement measurement of an electric motor rotor shaft surfaces.
Original measurement data related to publication:
T. Tiainen, R. Viitala, T.P. Holopainen, B. Hemming, Analysis of total rotor runout components with multi-probe roundness measurement method, Measurement, Volume 179, 2021, 109422, ISSN 0263-2241, https://doi.org/10.1016/j.measurement.2021.109422. (https://www.sciencedirect.com/science/article/pii/S0263224121004115)
All data is in raw format in CSV files. The measurements were triggered with a 1024-pulse rotary encoder and contain 5 rounds of data (5120 points).
The multi-probe roundness measurement algorithm implementations are available at: https://github.com/tuomastiainen/mpr-tools
Multi-probe roundness data, tactile measurement (Figures 6 and 9)
Raw data of four-point tactile roundness measurement.

Electrical runout data, simultaneous tactile and eddy current probe measurement (Figures 7 and 8)
Raw data of electrical roundness measurement, including one file with S1 and eddy data and another file with S1, S2, S3 and S4 tactile multi-probe roundness measurement data (simultaneous measurement, S1 data are equal in both files).
| Description | File name |
|---|---|
| Left polished tactile and eddy current measurement | electrical-runout/left-polished.csv |
| Left polished four-point tactile measurement | electrical-runout/left-polished-roundness.csv |
Scaling
- All tactile probe readings (S1 to S4) will need to be multiplied by 1/409.6 to obtain the values of the probes in micrometers.
- Eddy current probe data (analog voltage) was calibrated to the simultaneous eddy current probe measurement as described in the publication. The resulting calibration coefficient was 0.002130021300212892.
Names of variables

| S1 | Tactile displacement sensor 1 |
| S2 | Tactile displacement sensor 2 |
