W artykule przedstawiono wpływ dynamiki regulacji składowych wektora prądu stojana polowo-zorientowanego układu sterowania silnika synchronicznego z magnesami trwałymi PMSM na pojawiające się symptomy uszkodzenia, jakim jest zwarcie zwojowe uzwojenia stojana. Przedstawiono wpływ wartości pasma przenoszenia regulacji prądu oraz częstotliwości zasilania na wartość amplitud drugich harmonicznych sygnałów prądowych i napięciowych układu sterowania. Całość zilustrowano zarówno wynikami badań symulacyjnych, jak i eksperymentalnych.

This paper presents the influence of the dynamics of the control of the stator current vector components of the field-oriented control system of a permanent magnet synchronous motor (PMSM) on the appearing symptoms of a fault, which is a short-circuit within the stator winding. The influence of the value of the current control bandwidth and supply frequency on the value of the second harmonic amplitudes of the current and voltage signals of the control system is presented. The analysis is illustrated with both simulation and experimental results.

Modern drives with Permanent Magnet Synchronous Motors (PMSMs) require both efficient control structure to ensure excellent dynamics and effective diagnostic algorithms to detect the motor faults that can occur. This paper shows the combination of both mentioned aspects – the direct-axis based signals of the Field Oriented Control (FOC) structure are proposed as diagnostic signals to allow diagnosing the interturn short-circuit failure that can appear inside stator windings. The amplitudes of second order harmonics are selected as the fault indicators. Different modelling methods are analysed and compared in detail in this paper: an analytical mathematical model, a Finite Element Method (FEM)- based model and next verified using a laboratory setup. The results obtained using all the mentioned models proved that the proposed fault indices are increasing significantly with the number of shorted turns and are independent on the load torque level.

This paper deals with a novel diagnostic method for finding the stator winding short-circuit damage of induction motor drives. The proposed method is based on a new, simple idea of applying a modified, triple Park transform instead of using a computationally demanding on-line Fast Fourier Transform (FFT) analysis. The diagnostic method is based on the analysis of current and reference voltage vector components, which are the part of the Direct Field Oriented Control structure. The proposed method is verified experimentally using tests results. Further, the influence of speed, load torque and the parameters of PI regulators on the performance of the proposed diagnostic method are also discussed.
