IECON 2023- 49th Annual Conference of the IEEE Industrial Electronics Society, 2023 This paper analyzes the sensitivity of the rotor parameter estimation of an advanced Γ−model for multiphase induction machines. These machines exhibit inter-plane cross saturation and certain sub-topologies, such as variable phase-pole machines, may operate briefly with high rotor frequencies, which warrants the use of such models.
