One of the common defects of asynchronous engines that are widely used in industries and is the axis discharge defects that occur in engines. In this study, an asynchronous engine with a three-phase sincap hole was studied with Shannon entropy. Exenal disadvantages were created by expanding the rolling beds in the inside of both deck of the asynchronous engine. In the expanded rolling beds, a three-dimensional printer-protected brick was placed, ensuring that the rotor worked 0.20 mm away from the axis. The Asenkron engine was both robust and the axel gap defective under 25%, 50%, 75% and 100% load. Stator flow and vibration signals were recorded for each test condition. The accuracy of the stator flow and vibration signals was verified by the Fourier analysis. The effect of the axinal gap defect was studied by calculating the stator flow of the engine and entropic values of the vibration signals. The endropic values of the current and vibration signals of the defective engine of the solid and axle gap were compared. The results indicate that the axle gap defects cause a serious increase in the entropic value of the vibration signal but the stator stream does not show a significant change in the entropic value. The results show that the vibration signals can be used in entropic analysis for the detection of axinal evacuation defects.
