Modeling synchronous reluctance motors including saturation, iron losses and mechanical losses

The correct modeling and control of synchronous reluctance motors (SynRMs) requires a very good parameter identification. Accordingly, a simple experimental off-line approach for the calculation of the viscous friction coefficient, constant friction load, iron loss resistance and direct/quadrature inductances is presented in this paper. The iron loss resistance and the direct/quadrature inductances were introduced in the model as lookup tables. The motor behavior under vector control is analyzed considering both saturation and iron losses. Simulation results of a vector-controlled 2.2 kW SynRM are compared with experimental tests in order to show the effectiveness and accuracy of the proposed parameter identification methods.
