Comparison of different mathematical models of an electromechanical actuator

In the paper a brief comparison between different models of electromechanical actuator is presented. Main part of the paper is focused on model using Hamiltonian equations which employs flux linkages as state variables in the state space equations. Topological approach is used in the model implementation. This model is compared with one described by Lagrange formalism, which is much more popular in the literature. In both models eddy currents and hysteresis phenomenon are neglected to enable application of state space description. A 3-phase wye connected stator winding without a neutral wire is considered in detail as the most important connection schema in practical applications.
