To appreciate the utility of space vectors, one must first understand the limitations of classical AC machine analysis. Historically, three-phase electrical machines (such as induction and synchronous motors) were analyzed using per-phase steady-state equivalent circuits or complex time-domain differential equations with time-varying mutual inductances.
Given the growing importance of PMSMs in electric vehicles, aerospace, and renewable energy, Vas’s detailed treatment of these machines is especially significant. He distinguishes between: To appreciate the utility of space vectors, one
