Experimental Verification
The structure of the test rig is shown in Fig. 1. The test rig consists of an induction motor (4kW, 1400RPM) with load cell with a facility to collect the 3-phase current data directly to the PC at the user define sampling frequency. The motors in the test rig used in this experiment can be divided into 3 different conditions – Healthy, Stator Fault (short circuits) and Rotor Faults (broken rotor bars). The load of the motors is set at full load conditions. The data are collected at the sampling frequency of 1280 samples/s. The stator fault motor can be adjusted into 3 server level of the short circuits - 5 turn shot circuit, 10 turn short circuit and 15 turn short circuit while the rotor fault motor is one broken rotor bar.
