"Analysis of Electrical Machines" by Valeria Hrabovcova, Pavol Rafajdus, Pavol Makyš

The aim of this book is to present methods needed for the analysis of electrical machine performances in transients and steady-state conditions by means of simulations in MATLAB-Simulink and by means of FEM. This book is devoted to students, PhD students, postgraduates of electrical engineering, researchers, and scientists dealing with the analysis, design, and optimization of electrical machine properties. The purpose is to present methods used for the analysis of transients and steady-state conditions.

The parameter determination based on the design procedure is presented, and some examples are given. The authors used outputs of their long-time experiences in research and scientists work as university professors and use their pedagogical skills to create a guide on how to investigate parameters of equivalent circuits and apply them for investigation of transients and steady-state conditions.
The book is devoted to the postgraduate and PhD students, post PhD students, researchers, and scientist workers in electrical engineering, which deal with design and analysis of electrical machines’ performances and its optimization.
The readers should be educated in theory and basic principles of operation of all electrical machines in steady-state conditions to be able to follow application of mathematical apparatus needed for transient investigation in general theory of electrical machines and FEM analysis. The goal is to provide a guide for those who would like to learn how to investigate parameters of electrical machines and use them to design electrical machines and their optimization.
In three chapters the following methods are presented:
1) a method in which the parameters (resistances and inductances) are calculated on the basis of geometrical dimensions and material properties made in the design process,
2) a method of general theory of electrical machines, in which the transients are investigated in two perpendicular axes, and
3) FEM, which is a mathematical method applied to electrical machines to investigate many of their properties.
