Description
Summary:	This paper explores different high-fidelity, system-level models for permanent magnet synchronous machines. The main attributes examined are electromagnetic torque and forces representing the main contribution sources for noise and vibration in electrical powertrains. First, two types of electromagnetic models extracted from finite element analysis are presented: the current and flux-linkage state variable models. Afterwards, two force transformation models used for system-level vibro-acoustic computation are explored and a spectral convergence test is proposed. Procedures regarding model implementation, such as look-up table derivation/inversion are discussed and design trade-offs are analyzed. Finally, the different model results are benchmarked against a finite element model and the real-time performance is presented.
