Analysis of PM Inter-Turn Fault Based on LabVIEW and FFT

Abstract:

Inter-turn fault is the most probably fault in permanent motor. It is important to find the inter-turn fault and protect the permanent motor. Stator windings current is used to evaluate the inter-turn fault. A small resistance is connected with the permanent motor. The stator windings current is transferred to voltage and this signal is send to data acquisition system and transferred to digital signal. LabVIEW is used to control the data acquisition system and receive the digital signal. FFT is used to analyze the frequency character of the stator windings current and find the character of the inter-turn fault. Test shows that the permanent experimental system consisting of computer and LabVIEW can fully meet the requirements of permanent fault test and research.
