Hello, RMxprt solvers are based on magnetic equivalent circuit (MEC) analysis. For some PM machines, the q-axis armature reaction MMF will cause very complicated field distribution which is difficult to be analyzed by MEC. Therefore, RMxprt solvers takes into account the saturation caused by PMs, but not consider the effects of the armature current reaction on field saturation. This approximation will not cause significant errors in performance analysis for most PM machine designs.
