Nowadays, almost 70-80% of industrial applications have used induction motors as the main driving component of the production process. induction motor damage causes important problems for users, especially if used in industries that can cause production process to stop [1-2]. Based on surveys conducted by Electric Power Research Institute (EPRI) on 6312 motors and IEEE-IAS Motor Reability Working Group on 1.141 motors almost 41-44% induction motor damage occurs in the bearing [3-5]. Bearing damage based on location can be categorized as outer race bearing damage and inner race bearing damage. Bearing damage causes vibration, noise, increase in operating temperature, can even cause sparks due to friction between motor components that cause damage to other parts of the induction motor. [5]. Studies of bearing damage have been carried out by several previous researchers such as detecting bearing damage based on vibration analysis in [6], although this method is quite effective, analysis will get different results based on the location of sensor so it is difficult to determine the position of sensor. Paper [7], also conducted a bearing damage detection study using noise but in practice it did not show accurate results because there were other disturbing noise around. Paper [8] analyze magnetic flux from induction motors that contain a lot of harmonics. Observation through magnetic flux can produce very accurate results in monitoring motor conditions, this can be seen in the harmonic spectrum, but this method is not practical because it requires the installation of coils at the stator core, so that the motor operation must be stopped, and the small air gap also makes this method difficult to implement. Monitoring using a stator current analysis has also been carried out on [8-10], analysis on the stator current successfully performed detection analysis on rotor bar damage, airgap,
