Abstract
Designing a model for synchronous machines that are used in industrial applications is a challenging yet quintessential process. Owing to the huge size of the machine and its complex geometry, it has always been a tedious process to develop a full model of the machine and perform its analysis. Since the industrial synchronous machines are very huge, they are not manufactured in one single piece but are manufactured in many symmetrical pieces which are combined at the last. Because of this process, one major irregularity occurs which is additional air gaps in the rotor which may affect some machine parameters. So, in this thesis paper, a 2-D finite element model of a separately excited synchronous machine is created in FEMM 4.2 software with the additional air gaps in the rotor and the machine is analyzed for changes in the magnetic flux density due to the additional air gaps. After doing the finite element analysis of the machine with additional air gaps it was observed that the magnetic flux density in the air gap decreased with increase in the width of the additional air gaps.Description
