-This paper proposes a demagnetization fault diagnosis method for interior permanent magnet synchronous motors(IPMSMs). In particular, a demagnetization fault is one of the most frequent electrical faults in IPMSMs. This paper proposes an estimation method for permanent magnet flux. The method is based on linear interpolation. The effectiveness of the proposed method for diagnose demagnetization faults is verified through various operating conditions by finite element simulation.

This paper proposes the development of a new mathematical model dedicated to the diagnostic of the partial Demagnetization Fault (DF) in Permanent Magnet Synchronous Motor (PMSM). To do this, an extension of the Modified Winding Function Approach (MWFA) is proposed to accurately take into account the air gap asymmetry caused by the Demagnetization Fault (DF) in the PMSM inductances calculation. The calculated inductances are then used in the magnetically coupled electrical circuit model to simulate the PMSM behavior in the different operating modes. Finally, a diagnostic method based on the stator current spectral analysis is used to highlight the PMSM stator current spectral content in the various operating modes (with and without Demagnetization Fault).

“…At present, the EMA is usually driven by the permanent magnet synchronous motors (PMSMs) [4][5][6]. However, the EMA is inevitable to work in the condition with strong vibration and high temperature, which are easy to cause the demagnetisation of permanent magnets in PMSMs [7,8]. When compared with the PMSM, the switched reluctance motor (SRM) possesses simpler structure, stronger robustness, better heat resistance, and inherent fault tolerance [9,10].…”

This study proposes an integrated non-linear modelling method for an electromechanical actuation system directly driven by the switched reluctance motor (SDEMA). The mathematical model of the SDEMA system is established by energy analysis and calculation according to the proposed method, which omits the complex analysis of force or torque transmission in the cascade modelling method. By using the Lagrange-Maxwell equation and establishing the energy models of non-linear factors that include the friction, backlash, and flexibility, both the electromechanical coupling effects and the nonlinear factors of the SDEMA system are considered simultaneously in the proposed method. To verify the feasibility and effectiveness of the proposed method, three modelling methods of the SDEMA system are comparatively studied through the simulations and experiments. The results of the simulations and experiments indicate that the proposed integrative non-linear model can reflect the dynamic performance of the SDEMA system more accurately.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
