Abstract

COMSOL Multi physics is designed to be an extremely flexible package applicable to virtually many areas of research, science, and engineering. A consequence of this flexibility is that it becomes necessary to set up COMSOL Multi physics for a specific modeling task. It familiarizes with the modeling of generator (2D) in the AC/DC Module and illustrates different aspects of the simulation process. It steps through all the stages of modeling, from geometry creation to post processing. The program must mesh the geometry of the generator model before it can solve the problem. The powerful visualization of COMSOL Multi physics tools is accessible in the program’s post-processing mode. With this visualization time varying flux distribution and corresponding voltage output of the generator is possible to represent. Reliable output voltage of the generator depends upon the number of flux lines cut by the stator winding that depends on material property of stator and rotor. The materials may be magnetic or nonmagnetic. With various combinations of these materials corresponding output voltage and flux distribution are shown here with the process of modeling, defining, solving, and post processing using the COMSOL Multi physics graphical user interface. The purpose of this modeling is to find out best material combination which would produce significant amount of output voltage with least harmonic.
