As interturn short fault (ISF) in a permanent-magnet synchronous machine (PMSM) degrades its energy efficiency and may cause other problems, accurate fault diagnosis for the PMSMs is necessary. In this paper, we present a method that uses voltage and current residual components to diagnose the phase and the severity of the ISF in PMSMs. A faulty-winding model (FWM) is introduced to analyze the fault; the model describes a relationship between the voltage decrease of the faulty winding to the characteristics of the fault such as a fault resistance and a fault turn ratio. Based on the model, we suggest a fault index (FI) that shows the severity of the ISF. As the ISF induces residual components to both voltage and current, the proposed method utilized those components with the FWM. A least squares (LS) method is used to estimate the FI and to diagnose the ISF of PMSMs. Experimental results demonstrate that the proposed method diagnose the ISF effectively.
I. INTRODUCTION
PERMANENT magnet synchronous machines (PMSMs) are widely used in many industrial applications owing to their various advantages. PMSMs have higher efficiencies, higher power-to-volume ratios and more precise torque control than induction machines [1]. These features make them attractive candidates especially for electric and hybrid vehicles [2]. With the rising demand for the PMSMs in numerous industrial areas, there is an increasing possibility of unexpected system failures. Faults in PMSMs may result in plant breakdown, economic losses, and even human casualties. To prevent such catastrophies, fault diagnosis for PMSMs are necessary and has studied in recent years [3], [4].
VII. CONCLUSION
This paper proposes a algorithm that utilizes on voltage and current residual components based on the FWM to diagnose the ISF of the PMSM. Many studies have attempted to diagnose the ISF, but most of them did not consider the winding that has the fault, ans usually focused on very severe conditions. Because it can result increase in severity, or cause other faults such as a demagnetization fault, the ISF must be diagnosed in its early stages.
