KPCA and AE Based Local-Global Feature Extraction Method for Vibration Signals of Rotating Machinery

Table 7

Detail of datasets (the coding format is motor load-fault location-fault severity, for example, 1-IR-1 means the load is 1 hp, fault in inner race, and the fault width is 0.007 in).

Fault location	Fault width (in)	Motor load (hp)/motor rotation speed (r/min)
		0/1797	1/1772	2/1750	3/1730
Inner race	0.007	0-IR-1	1-IR-1	2-IR-1	3-IR-1
	0.014	0-IR-2	1-IR-2	2-IR-2	3-IR-2
	0.021	0-IR-3	1-IR-3	2-IR-3	3-IR-3
Ball	0.007	0-BA-1	1-BA-1	2-BA-1	3-BA-1
	0.014	0-BA-2	1-BA-2	2-BA-2	3-BA-2
	0.021	0-BA-3	1-BA-3	2-BA-3	3-BA-3
Outer race	0.007	0-OR-1	1-OR-1	2-OR-1	3-OR-1
	0.014	0-OR-2	1-OR-2	2-OR-2	3-OR-2
	0.021	0-OR-3	1-OR-3	2-OR-3	3-OR-3
