Test bench for emulating a variety of salient rotor electrical propulsion machines with a single permanent‐magnet synchronous machine drive

Abstract

The design of the powertrain of electric vehicles (EVs) and hybrid EVs could require the testing of different electrical machines (EMs) in order to evaluate their performances and to find the most suitable solution for that specific propulsion system. The number of EMs that can be tested is limited by economical and practical issues. Moreover, numerical simulations cannot always represent a reliable mean to understand the real behaviour of the system. This study presents a new mathematical model to emulate different virtual machines using only one real machine.
