| Abstract | This paper investigates the influence of the
magnetic saturation on the performance of a Synchronous
Reluctance Motor (SynRM) at steady-state. In addition, the
stability limits for the SynRM are studied using a suggested
more accurate method. The saturation and cross-saturation
effects on both direct (d) and quadrature (q) axis flux linkages
are considered. A Finite Element Method (FEM) is used to
obtain an accurate representation for the dq-axis flux linkages
relations. In order to reduce the calculation time of the finite
element analysis, a look-up table (LUT) for the dq-axis flux
linkages is generated based on the FEM to be used for
simulating the SynRM characteristics. It is found that the
magnetic saturation in the adopted motor results in an
enlarged region of stable operation of the SynRM by about 200
% compared with the unsaturated case. The results show the
importance of including the saturation factors on the
performance of the SynRM and its stability limits. Hence, the
magnetic saturation effect will not only reflect on the stability
of the motor but also on the whole drive system |
