A comprehensive review of modelling methods for multi-three-phase permanent magnet synchronous machines

In recent years, the multiphase machine has gained increased interest due to its potential advantages. Especially in the aircraft industry, as redundancy is very important for safety, which can be achieved by using a multiphase machine. The multiphase machine not only ensures continued safe operation in the event of a fault but also requires lower phase currents for the given power compared to a three-phase machine. The modelling of the machine is important to evaluate the behaviour in simulation and in real-time for the project BeHyPSy. This paper presents different modelling methods of multi-three-phase PMSM, such as Vector space decomposition, General Decoupling, Multi-stator, Voltage-behind-reluctance Model. All the methods have their own advantages and limitations. The research has investigated several machine modelling techniques and concluded that, among all the approaches, the Voltage-behind-reluctance method is the most suitable for the BeHyPSy project, as it accurately represents internal machine phenomena and enables the simulation of single-phase and multiphase faults.
