This paper classifies the drive topologies of openend winding (OEW) permanent magnet synchronous machines (PMSMs) and investigates their electrical differences compared to conventional PMSMs. The mechanism of zero-sequence current (ZSC) generation is identified, showing that it originates from the zero-sequence back-electromotive force (back-EMF) and the zero-sequence cross-coupling voltage. Using an 8-pole, 48-slot interior PMSM model, the influence of ZSC is analyzed through finite element analysis (FEA). The results reveal the relationship between machine topology, inherent zero-sequence voltage sources, and the resulting current behavior. These findings offer valuable insights for optimizing the design and control of OEW-PMSM drives to minimize ZSC effects, improve efficiency, and enhance overall system performance.
