| dc.description.abstract | A parametrized 2D model of a permanent magnet synchronous machine is developed in the finite elements method software COMSOL Multiphysics, along with a graphical user interface to control it. The GUI provides automatic construction of geometry based on specified input parameters, application of boundary conditions and equations, and post-processing of results. Algorithms are implemented to apply automatic periodicity settings and winding layouts for single layer and double layer integer and fractional slot windings. The output of the model is validated by comparing to analytical formulas and to other studies with known input parameters and results.
The purpose of developing the the application is educational, allowing simulations to be performed without requiring in-depth knowledge of FEM. A range of sample studies are presented in this respect, to indicate possible areas of application within the educational setting. It is found that simulations can be performed very efficiently, indicating that the application could provide a valuable tool for studying electrical machines. Depending on further development and implementation of additional functionality, the application could probably also be used in the process of designing machines. | |
