I. Introduction
Induction motors are the most widely employed electrical machines. They represent % of the consumed power in industries [1]. Several kinds of failures may present themselves during an operation, such as bearing faults, air gap eccentricity, and broken rotor bars, in the case of the squirrel cage motor. Sudden failure of an induction motor due to any of the causes stated above may lead to significant loss of time and money. Therefore, its replacement or repairment is of the utmost importance. It is because of these reasons that an early diagnosis of the health status of the motor is necessary. Broken rotor bars in squirrel cage motors represent % of the total failures of these types of machines. This fault is caused by defective fabrication or irregular load levels during operation [1].
