“…The inductances in each set of windings are asymmetric shown in (3). However, the inductances of equivalent PMSM are symmetric because the coupling between two sets of windings compensates the asymmetric inductances, and the symmetrical inductances in equivalent PMSM obtains only when currents in two sets of windings are symmetrical.…”

A fault tolerant control strategy for dual three-phase permanent magnet synchronous motor (DTP-PMSM) with 0° phase shifting between two windings is proposed in this paper. When a DTP-PMSM suffers from single-or two-phase open-circuit fault, to maintain the torque performance, current in faulty phase must be compensated by other healthy phases, which causes asymmetric self-and mutual inductances. Therefore, the 2 nd harmonic component can be observed in the dq-axis currents and torque ripple also increases. To analyse this harmonic component in two types of faults, post-fault model of no-phase-shifting DTP-PMSM based on vector space decomposition (VSD) method is built in this paper. Then, proportionintegral-resonant (PIR) controller which can be used to suppress the specific periodic disturbance is applied to compensate the 2 nd harmonic components. As the resonant controller is rarely dependent on motor parameters, phase and amplitude of current harmonic, the PIR controller can be applied in no-phase-shifting DTP-PMSM to suppress the harmonic caused by single-and two-phase open-circuit faults. The experimental results validate the effectiveness of the proposed fault tolerant control under single-and two-phase opencircuit faulty conditions.

ZusammenfassungGetriebelose Windgeneratoren mit Zahnspulen und massivem Rotorjoch sowie der Möglichkeit zum Weiterbetrieb bei teilweisem Umrichterausfall stellen eine besondere Herausforderung in der Auslegung dar. Zunächst wird untersucht, welche Zahnspulenwicklungen im Hinblick auf die zulässigen Rotorverluste geeignet sind. Nachdem entsprechende Wicklungsvarianten gefunden sind, wird die Maschinengeometrie optimiert. Dabei wird das Optimierungspotenzial, welches in den kurzen Wickelköpfen der Zahnspulenmaschine liegt, berücksichtigt. Nach der Optimierung erfolgt eine Nachrechnung der Verlustbilanz und eine Auswertung der magnetischen Geräuschanregung mithilfe von transienten, nichtlinearen Finite-Elemente-Simulationen.
