A new cross-saturated torque model of the synchronous reluctance machine (SynRM) including a direct incorporation of cross-saturation effects is presented. Direct-quadrature (d-q axes) flux linkages for both saturation and cross-saturation conditions, obtained experimentally through current decay test using open winding fixed rotor method, are accurately curve-fitted and linearization between the two extremes yielding analytical functions for cross-coupled d-q axes flux linkages. These flux linkages are used to achieve a cross-saturated flux linkage-based torque model for highly utilized SynRM. The accuracy of the developed torque model is evaluated by comparing with the experimentally measured torque of a 5.5 kW SynRM in a dynamometer test bench which also measures and account for the effect of iron losses. The close similarity of the experimental results with the developed model proves the accuracy of the model and its suitability for direct incorporation in control algorithms of advanced SynRM drives without the use of look-up tables.
