Abstract
Induction motors are commonly used in many different applications. The importance of these motors comes from their ruggedness, reliability, and low maintenance cost. Generally, the driving system of these motors can be vulnerable to injury of different types of faults during the operation, which leads to failure in continuous optimal operation of the system. This paper proposes a new simple algorithm to detect and classify the fault may occur in the driving system (in the Voltage Source Inverter VSI) of induction motor. The proposed method uses three parameters: First, the per phase average value of the stator current. Second, the Pulse Width Modulation (PWM) signal. Third, the switch voltage (drain to source voltage). The method is designed based on using the logic system. It is designed to decide whether the driving system is healthy or faulty. Moreover, the logic system can specify the fault location over the driving system. MATLAB 2020a is used to validate the results.
