AC Motor Testbed under constant or varying speed (AC.z05)

!!!!! IMPORTANT !!!!! This file is compressed into separate files (total 7 files; AC.z01, AC.z02, AC.z03, AC.z04, AC.z05, AC.z06, AC.zip), so you must extract them after securing all of the separate files below. Gather all of the data from the link below, store them in one folder, and then extract "AC.zip" them. A comprehensive fault dataset was constructed using a testbed composed of AC motors with different capacities and fault types. This dataset includes vibration, current, and torque measurements under both constant(50Hz) and variable speed conditions(50~52Hz, 50~58Hz). In this case study, four motor fault types were simulated: misalignment, bearing fault, winding fault, and journal bearing clearance fault. Current (R-, S-, T-phase; sampling rate=100kHz), Vibration (z-axis; sampling rate=25.6kHz), Torque (sampling rate=25.6kHz) are included.
