ESTOGU: A Multimodal Motor Condition Monitoring Dataset for Fault Diagnosis in Electrical Machines   This dataset contains vibration, current, and voltage measurements collected from six different electrical machine conditions under two experimental setups (**Inverter-Fed (With Driver)** and **Grid-Fed (Without Driver)**).     All experiments were conducted at the **Electrical Machines Laboratory, Eskişehir Technical University (ESTU), Turkey**. ---   ## 📂 Folder Structure   ESOGU_Dataset/ ├── Metadata/ # Background and setup information │ ├── Experimental Setup Description.pdf │ ├── Index.csv │ └── Motor RPM Values.pdf ├── With_Driver/ # Data collected with inverter driver │ ├── N/ # Normal condition │ ├── BB/ # Bearing Ball defect │ ├── BR/ # Bearing Ring defect │ ├── RB3/ # 3 broken rotor bars │ ├── RB5/ # 5 broken rotor bars │ └── SW/ # Shorted Winding ├── Without_Driver/ # Data collected without inverter driver │ ├── N/ │ ├── BB/ │ ├── BR/ │ ├── RB3/ │ ├── RB5/ │ └── SW/ └── README.md └── Dataset_Structure.pdf   ---   ## 📑 Filename Convention   Each data file follows the pattern:   {MACHINE}{LOAD}{FREQ}.csv   - **MACHINE**:     - `N`   → Normal     - `BB`  → Bearing Ball defect     - `BR`  → Bearing Ring defect     - `RB3` → 3 broken rotor bars     - `RB5` → 5 broken rotor bars     - `SW`  → Shorted winding     - **LOAD**: One of `{000, 111, 222, 333, 444, 555}`     - **FREQ**:     - For **With Driver**: `{45, 45.5, 46, 46.5, 47, 47.5, 48, 48.5, 49, 49.5, 50}` Hz     - For **Without Driver**: `50` Hz (constant)     **Example:**   - `BB_000_45.csv` → Bearing Ball fault, load 000, frequency 45 Hz   - `RB3_333_48.5.csv` → 3 broken rotor bars, load 333, frequency 48.5 Hz   - `N_555_50.csv` → Normal condition, load 555, frequency 50 Hz     ---   ## 📊 Data Format   Each `.csv` file contains **8 columns**:   | Column          | Description                                                | Units    | |--------------   |--------------------------------------------  -|---------| | Timestamp     | Time index of recording                            | s           | | VibrationX      | Vibration signal along X-axis                    | V           | | VibrationY      | Vibration signal along Y-axis                    | V           | | VibrationZ      | Vibration signal along Z-axis                    | V           | | Current1         | Phase current 1                                         | V           | | Current2         | Phase current 2                                         | V           | | Current3         | Phase current 3                                         | V           | | Voltage           | Phase-to-phase voltage                           | V           |   ---   ## 🧪 Experimental Setups   - **With Driver**:     Measurements taken under **6 loads × 11 frequencies** for each machine condition.     - **Without Driver**:     Measurements taken under **6 loads at constant 50 Hz** for each machine condition.     ⚠️ Note: Reference frequency values correspond to approximate motor RPM values (see `Metadata/Motor RPM Values.pdf`).     ---   ## ⚡ Fault Creation   The dataset includes measurements from both healthy and faulty motors. Faults were introduced in a **controlled laboratory environment** to ensure reproducibility and comparability:   - **Rotor Bar Faults (RB3, RB5):**     Artificial defects were introduced by intentionally breaking **3 or 5 rotor bars** in the rotor cage. This simulates common rotor asymmetries and cracked bar conditions observed in industry.   - **Stator Shorted Winding Fault (SW):**     Short-circuit faults were created by **damaging insulation between adjacent turns** of the stator winding, resulting in localized inter-turn short circuits.   - **Bearing Faults (BB, BR):**     Bearings with localized defects were used. Defects were created by **drilling small holes or grooves** in the **ball elements (BB)** or **inner/outer races (BR)** of the bearings to replicate realistic wear and pitting.   - **Healthy Motor (N):**     At least one motor was kept fault-free to serve as a reference baseline.   These synthetic faults follow established practices in experimental motor fault research and are comparable to widely used benchmark datasets (e.g., CWRU, Paderborn).   ---   ## 📘 Notes   - Sampling rate, measurement duration, motor RPM values, and experimental setup details are given in `Metadata/`.   - All signals are synchronized in the same file.   - Dataset collected at the **Electrical Machines Laboratory, Eskişehir Technical University (ESTU), Turkey**.     ---
