Influence of the Stator Windings Configuration in the Currents and Zero-Sequence Voltage Harmonics in Permanent Magnet Synchronous Motors With Demagnetization Faults
IEEE Transactions on Magnetics, 2013Co-Authors: Julio César Urresty, Jordi-roger Riba, Luís RomeralAbstract:Demagnetization faults in permanent magnet synchronous motors may generate specific fault harmonic frequencies in the stator currents and the Zero-Sequence Voltage component (ZSVC) spectra. Hence, by analyzing the stator currents or/and the ZSVC spectra it is possible to develop fault diagnosis schemes to detect such faults. In order to have a broad view of such effects, a representative set of stator windings configurations must be considered. By analyzing different stator windings configurations this paper shows that the amplitude of the harmonic frequencies of both the stator currents and the ZSVC spectrato be analyzed are significantly influenced by the stator windings configuration. It is also proved that depending on the winding configuration, new harmonic components may emerge in both spectra. The results presented in this paper may help to develop fault diagnosis schemes based on the acquisition and further analysis of the stator currents and the ZSVC harmonic components.

Detection of Demagnetization Faults in Surface-Mounted Permanent Magnet Synchronous Motors by Means of the Zero-Sequence Voltage Component
IEEE Transactions on Energy Conversion, 2012Co-Authors: Julio César Urresty, Jordi-roger Riba, M. Delgado, Luís RomeralAbstract:This paper develops and analyzes an online methodology to detect demagnetization faults in surface-mounted permanent magnet synchronous motors. The proposed methodology, which takes into account the effect of the inverter that feeds the machine, is based on monitoring the Zero-Sequence Voltage component of the stator phase Voltages. The theoretical basis of the proposed method has been established. Attributes of the method presented here include simplicity, very low computational burden, and high sensibility. Since the proposed method requires access to the neutral point of the stator windings, it is especially useful when dealing with fault tolerant systems. A simple expression of the Zero-Sequence Voltage component is deduced, which is proposed as a fault indicator parameter. Both simulation and experimental results presented in this paper show the potential of the proposed method to provide helpful and reliable data to carry out an online diagnosis of demagnetization failures in the rotor permanent magnets.

Detection of inter-turns short circuits in permanent magnet synchronous motors operating under transient conditions by means of the zero sequence Voltage
Proceedings of the 14th European Conference on Power Electronics and Applications, 2011Co-Authors: Julio César Urresty, Harold Saavedra, Jordi-roger Riba, Luís RomeralAbstract:This work proposes the zero sequence Voltage component (ZSVC) of the stator three-phase Voltages as a method for detecting winding inter-turns short circuits in permanent magnet synchronous motors PMSM operating under transient conditions. Additionally it proves the linear relationship between the ZSVC and speed, which is effectively used as a fault severity index. The acquired ZSVC temporal signal is processed by means of the Hilbert-Huang transform (HHT). Experimental results presented in this work show the advantages of the method to provide helpful data for online diagnosis of stator winding inter-turn faults.

dual space vector control of open end winding permanent magnet synchronous motor drive fed by dual inverter
IEEE Transactions on Power Electronics, 2016Co-Authors: Quntao An, Zhuang Peng, Jin Liu, Li Sun, Lizhi SUNAbstract:This paper proposes a dual-space vector control scheme for the open-end winding permanent magnet synchronous motor (OEW-PMSM) drive fed by the dual inverter with a single dc supply. Potential Zero-Sequence current in the open-end winding drive system has to be considered since it causes circulating current in the winding and leads to high current stress of power semiconductor devices and high losses. Zero-Sequence current in open-end winding ac motor drives is usually caused by the Zero-Sequence Voltage, and therefore switching combinations which do not produce Zero-Sequence Voltage are used to synthesize the reference Voltage in existing methods. But even so, the Zero-Sequence Voltage can also be produced by the dead time of the inverter. In order to suppress Zero-Sequence current in the OEW-PMSM drive, a dual-space vector control scheme is proposed and a novel dual-inverter space vector pulse width modulation (PWM) with the Zero-Sequence Voltage reference is employed to regulate system Zero-Sequence Voltage in this paper. Compared with existing dual inverter PWM strategies, the novel algorithm build a regulation mechanism for the Zero-Sequence Voltage. The proposed method is compared with the conventional vector control by simulations and experiments, and the results shown that the proposed scheme can suppress Zero-Sequence current effectively.
