University of Ottawa Electric Motor Dataset – Vibration and Acoustic Faults under Constant and Variable Speed Conditions (UOEMD-VAFCVS)

Each motor has different types of faults artificially created by SpectraQuest. Data is collected using three accelerometers and a microphone (the first, third and fourth columns are accelerometer data, the second column is acoustic data, and the fifth column is temperature data).

The labelling of data is as follows {Letter}-{Letter}-{Number}-{Number}: The following values represent the possibilities for the first letter: - H indicates healthy - R indicates rotor - S indicates stator - V indicates voltage - B indicates bowed - K indicates broken - F indicates faulty The second letter is represented by the following possible values: - H indicates healthy - U indicates unbalance - M indicates misalignment - W indicates winding - R indicates rotor - A indicates rotor bars - B indicates bearing The combination of both letters indicates the health state of the motor present in the data sample (e.g. H-H = a healthy motor, S-W = a stator winding fault).
