A new modeling and simulation platform-Mworks for electrical machine based on modelica

Traditional modeling tools such as MATLAB/simulink for the dynamic characteristic simulation of electrical machine has been constrained to cumbersome and complex calculation to obtain the causal relation between input and output of the block. This paper introduces a new modeling and simulation platform-Mworks based on the Modelica language, which enables convenient and efficient modeling and simulation of complex, multi-domain physical systems described by differential, algebraic and discrete equation and supports non-causal modeling, meaning that a modelpsilas terminals do not necessarily to be assigned an input or output role. So it is easy to learn and well suited to simulate the dynamic characteristic of electrical machine. To validate the correctness of the new modeling tool in detail, the model induction machine is established, in which the motor was connected with symmetrical three phase supply and the output waveform accords the running characteristic of the motor.
