This work presents a general approach for modeling multi-phase electrical machines and highlights the associated challenges. The electrical model of an example 50kW interior permanent-magnet synchronous machine (IPMSM) is developed. Transformations into stationary and rotating reference frames for multi-phase machines are presented and illustrated in context of the example machine. The transformations are then used to reduce the computational complexity of obtaining model parameters. The results for the example machine obtained by finite element (FEM) analysis are presented and implications for model validity and control challenges are discussed.
