An SPM Motor Drive Dressed as IPM Motor Drive for a Flexible Test Bench of Salient Rotor Propulsion Machines

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