N2 - The fault that often occurs on induction motors, can be caused by the construction of the motor itself (production defects), the fault to bearings, stator, rotor, and others. If the motor can rotate but does not follow the symmetrical rotation between the stator and rotor, this is called eccentricity. This is an air gap imbalance in the motor. Static eccentricity can still rotate with the same core position, but the width of the air gap becomes asymmetrical. In this study, the motor was reconstructed with a case of static eccentricity. Once reconstructed, it detects a steady-state stator current signal. Apart from static eccentricity, it is added if the supply voltage is unbalanced. The signal obtained will be processed using Discrete Wavelet Transform (DWT). The result of the detection percentage is obtained in the condition of the eccentric motor with a balanced voltage of 83.3%, Over Voltage (OV) 50%, Under Voltage (UV) 100%, the data is obtained without load. Meanwhile, the detection rate for motors and generators is very low for the OV eccentricity motor of 16.67%, UV 66.67%.
