- Abstract
- This paper analyzes the characteristic of an inter-turn fault diagnosis according the parameter of permanent magnet synchronous motor (PMSM). If the inter-turn fault occurs in PMSM, the d-axis current is different from the d-axis current in the healthy condition. Through the difference between the d-axis current in the healthy and faulty condition, the inter-turn fault can be detected. Consequently, the magnitude of the d-axis current determined the characteristic of the inter-turn fault diagnosis. The offline diagnosis was performed by applied voltage into the PMSM. The performance of the offline diagnosis depended on the parameter of the PMSM. Thus, the performance of the offline diagnosis was analyzed according parameter of the PMSM that is fault resistance, winding resistance and saliency ratio. In addition, to verify analytical method, inter-turn fault diagnosis is performed by co-analysis that was the link between the finite element analysis (FEA) and the control simulation tool.
