A Pentacle Mode Vectorial Control for Five-Phase PMSMs

The pentacle-wired 5$\Phi$ PMSM has the advantage of high-power density and is being nominated for high-speed applications. Frequently, its vectorial control is referenced to its counterpart of the star-connection, by converting motor parameters into the star-wired mode, which is hereinafter termed star-mode vectorial control. However, this model conversion causes some understanding obstacles in $\mathrm{L}_{\mathrm{d}}$ and $\mathrm{L}_{\mathrm{q}}$. In light of this, a pentacle-mode vectorial control is put forward in this work, where only the conversion of line-to-phase current and phase-to-pole voltage is necessary, rather than performing the model conversion, and it also benefits the drive commissioning. In addition, an off-line parameter measurement method is also provided. The proposed pentacle-mode vectorial control as well fits the imaginary pentacle-wired drive that is with a star-wired winding.
