Vibration, Acoustic, Temperature, and Motor Current Dataset of Rotating Machine Under Varying Load Conditions for Fault Diagnosis

This dataset presents time-series dataset including vibration, acoustic, temperature, and motor current data for rotating machines under varying load conditions. The conditions of the rotating machine include normal, bearing inner race faults, bearing outer race faults, shaft misalignment, and rotor unbalance with three different load conditions. ---- Description of vibration file format ---- Vibration data file contains five columns namely ‘Time Stamp’, ‘x_direction_housing_A’, ‘y_direction_housing_A’, ‘x_direction_housing_B’, and ‘y_direction_housing_B’. The unit of the vibration is ‘gravitational constant (g)’. aaaaNm_bbbb_cccc.mat : This file includes vibration data of the condition of "bbbb" with "cccc" of severity and "aaaa" load condition. ---- Description of acoustic file format ---- Acoustic data file contains two columns namely ‘Time Stamp’, and ‘values’. The unit of the acoustic is ‘Pascal (Pa)’. aaaaNm_bbbb_cccc.mat : This file includes acoustic data of the condition of "bbbb" with "cccc" of severity and "aaaa" load condition. ---- Description of temperature, and motor current file format ---- Temperature and motor current data file contain six columns namely ‘Time Stamp’, ‘Temperature_housing_A’, ‘Temperature_housing_B’, ‘U-phase’, ‘V-phase’, and ‘W-phase’. The unit of the temperature and motor current are ‘Celsius (℃), and ‘ampere (A)’, respectively. aaaaNm_bbbb_cccc.tdms : This file includes temperature and motor current data of the condition of "bbbb" with "cccc" of severity and "aaaa" load condition.
