Computer aided models for the characterization of synchronous reluctance motor drive systems

A computer aided model based on the use of an indirect coupled and iterative approach is used to predict the performance characteristics of synchronous reluctance motor (SynRM) drives. The approach indirectly couples a two dimensional (2D) nonlinear finite element (FE) model, which accounts for magnetic saturation and space harmonics, to a time variant state space model describing the SynRM drive system. The effects of various modes of excitation on the axially laminated anisotropic (ALA) rotor synchronous reluctance motor (SynRM) drive systems performance characteristics are studied.
