Induction Motor Vibration and Acoustic Cellular Device (IM-VACD)

The dataset consists of constant and variable speed data collected from 8 different D396 Marathon Electric 3-phase motors. Each motor has different types of faults artificially created by SpectraQuest. Data is collected using three cellphones sensors (accelerometers and a microphone) (the first column is acoustic data, the second, third and fourth columns are accelerometer data [x,y,z axis data]).
The labelling of data is as follows {Letter}-{Letter}-{Letter}-{Number}-{Number}:

The following values represent the possibilities for the first letter:
- A indicates iPhone 13
- B indicates Samsung Galaxy S6
- C indicates Samsung Galaxy A50

The following values represent the possibilities for the second letter:
- H indicates healthy
- R indicates rotor
- S indicates stator
- V indicates voltage
- B indicates bowed
- K indicates broken
- F indicates faulty

The third 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).

The first number represents:
- 1 is for a constant speed of 15 Hz
- 2 is for a constant speed of 20 Hz
- 3 is for a constant speed of 25 Hz
- 4 is for a constant speed of 30 Hz

The second number represents:
- 0 for a no load condition
- 1 for a loaded condition

The duration of data collection was 10 seconds at a sampling frequency of iPhone 13 at 100 Hz, Samsung Galaxy S6 at 200 Hz, and Samsung Galaxy A50 at 490 Hz for accelerometer data. For acoustic data, all phones were collected at 42,000 Hz for a 10-second data duration. Each file contains 420,000 samples.
Raw data is provided in the folders as comma separated values files (.csv).
