Universal Model of a Multiphase Permanent Magnet Synchronous Motor

Abstract

Models of the electrical machines are used in the process of development control system and verification of them. Nowadays multiphase machines are attracting attention due to their reliability; however, standard MATLAB libraries are limited by 5-phase and 3-phase models. This paper considers a universal model of 3-, 5-, 6-, 7-, 9-phase permanent magnet synchronous motor with an open-end winding configuration. The open-end winding configuration allows to examine star-connection, delta-connection, or independent windings from fed H-bridge inverter that helps exploring fault tolerant control strategies. The model was developed using standard blocks of MATALB Simulink and can be used as a component of SimPowerSystem. Simulation results are provided as well as a link to the library for use free of charge.
