There is one text that answers this question definitively: (Part of the Monographs in Electrical and Electronic Engineering series, Oxford University Press). "Current Model" (good at zero speed)

Instead of treating induction, synchronous, and permanent magnet motors as separate entities, the space vector approach provides a unified theory that applies across the board. creating 6th harmonic torque pulsations.
