Electric motors with more than three phases have many advantages comparing to ordinary three-phase motor. For this reason it is natural to pay attention to them and to work on advanced control methods. Control algorithms development requires to operate with the model of motor. This paper presents the modeling concept of the nine-phase permanent magnet synchronous motor (PMSM) in three times three-phase arrangement fed by nine-phase voltage source inverter (VSI). Magnetic interaction between phases and phase groups had to be taken into account. The paper also provides relationship between model parameters and real motor ones, depending on the windings configuration. It shows the comparison between the simulation and experimental results with real motor. Used method of motor parameters measurement and the subsequent conversion of these parameters into d-q coordinates is clarified in this paper.
