Abstract
In this thesis, accurate, simple and fast model of AC machines is presented. The proposed model can describe and explore the machine{u2019}s behavior and performance accurately. The proposed models are categorized as coupled FEM-Circuit modeling approaches. A so called combined FEM-Circuit (or staged FEM-Circuit) model is proposed to investigate the model of SynRM including effect of cross-magnetic saturation. In addition, a coupled FEM-Circuit model is introduced to simulate the performance and dynamic behavior of a squirrel cage induction machine. Also, a simple and systematic design technique is presented to explore and select the optimum design parameters of a SynRM that can achieve optimal pullout torque and minimum ripples, and to study their effect on the motor performance. In addition, the evaluation of a proposed model of self-excited induction generator (SEIG) including the effect of inductance saturation and its rate of change is investigated. The model is validated experimentally using a test rig of 7.5 kW SEIG
