Mobile Application to Detect Induction Motor Faults

An Android-based application has been developed which can convert any mobile phone with inbuilt accelerometer into a squirrel cage induction motor (SCIM) fault diagnosis tool. To detect the faults, the mobile phone needs to be attached to the motor, and the application will record the motor vibration signal using the inbuilt accelerometer. After the recording, the faults are detected by locating the fault frequencies in the motor vibration spectrum. The developed application can also detect the motor faults from any previously recorded files of vibration data. The application has been tested on a 22 kW SCIM using Moto G4 Plus and Moto G5 Plus Android phones. Unlike the other SCIM fault diagnosis systems, the proposed method does not require any dedicated sensors, processing platforms, and power supply arrangements.
