Modelling of electrical machines using the Modelica Bond-Graph Library

The paper presents the bond graphs approach to modelling electrical machines for controlled electromechanical systems applications. The bond graph models of electrical machines are based on the models of ideal couplings: transformer and electromechanical couplings, respectively. Using the couplings models as building blocks the models of electrical machines (brushed and brushless DC machines with permanent magnets, and synchronous machine) have been developed in terms of bond graphs. The models have been elaborated using the Modelica Bond-Graph Library and the DYMOLA package.
