Comparison of the ${\mbi A}^{*}{-}{\mbi A}$ and ${\mbi T}, \Phi{-}\Phi$ Formulations for the 2-D Analysis of Solid-Rotor Induction Machines

Dynamic Preisach model identification applying FEM and measured BH curve

“…The losses inside steel is increasing when increasing the angular velocity as it can be seen in Figure 7, too, but the results at smaller angular velocity obtained from static and dynamic simulations are more or less the same. The simulated results are in a very good agreement with the results in reference (Marcsa and Kuczmann, 2009), and in the literature of induction motors, e.g. (Arkkio, 1987;Bastos and Sadowski, 2003;Davey, 1998).…”

“…Figure 7 shows the torque as a function of the angular velocity, it is similar to the results of linear simulations (Marcsa and Kuczmann, 2009). The losses inside steel is increasing when increasing the angular velocity as it can be seen in Figure 7, too, but the results at smaller angular velocity obtained from static and dynamic simulations are more or less the same.…”

“…30.a In this paper, the three phase induction motor of TEAM Problem No. 30.a (Marcsa and Kuczmann, 2009) has been modified. The original eddy current field problem consists of induction motors with linear B-H relationship.…”

“…The arrangement of the three phase induction motor problem can be found e.g. in (Marcsa and Kuczmann, 2009). The phase groups of the three phases lag each other in phase by 1201.…”

“…The eddy current field problem has been solved by the magnetic vector potential formulation, B ¼ r  A (Bír o, 1991;Kuczmann and Iv anyi, 2008;Marcsa and Kuczmann, 2009). After some mathematical formulations, the following partial differential equation can be obtained:…”
