Abstract

Multi-Three-Phase machines are increasingly popular due to the inherent benefits of modularity and fault-tolerance. However, modelling Multi-Three-Phase machines behaviour can be an arduous task. The system complexity may require iterated computationally demanding procedures involving Finite Element software to derive realistic inductance matrices and the harmonic content of the Back Electro-Motive Force. This paper demonstrates a comprehensive simplified analytical method for numerically computing the Magneto-Motive Force, torque, inductance matrix and the Back Electro-Motive Force of Multi-Three-Phase machines. The results are compared with Finite Element Models, for the same machine geometry of a three-phase and nine-phase machine, showing a difference below four percent on the evaluation of the inductance matrix.
