The present paper describes the development of a 5-phase permanent magnet synchronous machine (PMSM) drive model suitable for fault analysis. The aim of the proposed model is to serve as a tool to predict machine behavior, extract fault signatures and test post-fault remedial strategies in fault-tolerant PMSM drive systems, which are experiencing increasing interest in electrical transport systems. Specifically, winding open-circuit, terminal short-circuit and the permanent opening or closing of inverter switch faults are considered. In addition to describing the implementation of the drive model, a validation via a Finite Element (FE) analysis is presented.
