The damages were generated using both artificial and natural ways. More specifically, an electric discharge machine (EDM), a drilling, and an electric engraving were used to manually produce the artificial faults. While the natural damages were caused by using accelerated run-to-failure tests. The data collection process for both types of damages, i.e., artificial and real, was exposed under working conditions with different operating parameters such as loading torque, rotational speed and radial force. In total, the Paderborn datasets was collect under 6 different operating conditions including 3 conditions with artificial damages (denoted as domains I, J and K) and 3 conditions with real damages (denoted as domains L, M, and N). For example, the loading torque varies from 0.1 to 0.7 Nm and the radial force varies from 400 to 1000 N, while the rotational speed is fixed at 1500 RPM. Each operating condition (i.e., domain) contains three classes, namely, healthy class, inner fault (IF) class, and outer fault (OF) class. To prepare the data samples for the Paderborn dataset, we adopted sliding windows with a fixed length of 5,120 and a shifting size of 4,096 (Ragab et al. 2021). As such, we generated 12,340 for each artificial domain (i.e., I, J, and K) and 13,640 samples for each real domain (i.e., L, Mand N) respectively.Agency for Science, Technology and Research (A*STAR)AME Programmatic Funds (Grant No. A20H6b0151)Agency for Science, Technology and Research (A*STAR)Career Development Award (Grant No. C210112046)
