Analysis of acoustic spectrum of three-phase induction motor at stator winding damages
Języki publikacji
Abstrakty
The paper concerns the diagnostics of windings defects in three-phase induction motors basing on the electric machine noise analysis. With the help of the computer software, the acoustic spectrum was analysed and the dominant diagnostic harmonics of noise of the three-phase slip-ring induction motor have been determined. The failures of the following type: the internal shorting between two phases and the short-circuit of the stator coil have been investigated. The problem of the increase of the damage degree was also analysed. Within the framework of the comparative diagnostic methodics, the properties and parameters of the symmetrical three-phase induction motor are the basis for a state valuation of the electrical machine. It was illustrated that the change of the acoustic spectrum can give information about the technical state of the motor. The interesting methodology of noise research consists in investigations for frequencies of a wide range. All presented in this paper measurements have been done for the three-phase induction slip-ring motor placed on the work-stand.
