Use of axial flux in the detection of electrical faults in induction motors

The article presents the possibility of using an axial flux in the detection of electrical faults in induction motors. The work presents results obtained for a faulty rotor squirrel cage and a stator winding short-circuit. Fault detection and identification is based on the analysis of symptoms obtained from the Fast Fourier Transform of a voltage induced by an axial flux in a measurement coil. The laboratory research was conducted on a small power induction motor using the LabView software.
