This study introduces to usage of an up-to-date software platform named.NET for the web-based learning models directed to education of a more special area that includes electrical machines courses in where dynamic and interactive simulations are also included. Users can perform several didactic educational activities by means of these dynamic simulations. To illustrate the system, an interactive dc motor simulation is given in the paper. Mathematical model of the motor is solved in the .NET framework using C# language. Parameters of the model can easily be modified via the dynamic web pages designed for the interactive simulation and then the system response is also observed graphically at the same time against the modifications. Thus, the system presented in this study accelerates the learning period with its instructional and dynamic structure.
