Electric Machines

This second edition covers advanced subjects in electric machines, starting from principles, to applications and case studies with ample graphical results. This book is intended for second (and third) semester course, treating topics like modeling of transients, control principles, electromagnetic and thermal FEA and optimal design.

This Second Edition extensively covers advanced issues/subjects in electric machines, starting from principles, to applications and case studies with ample graphical (numerical) results. This textbook is intended for second (and third) semester courses covering topics such as modeling of transients, control principles, electromagnetic and thermal finite element analysis, and optimal design (dimensioning). Notable recent knowledge with strong industrialization potential has been added to this edition, such as:

• Orthogonal models of multiphase a.c. machines

• Thermal Finite Element Analysis of (FEA) electric machines

• FEA-based-only optimal design of a PM motor case study

• Line start synchronizing premium efficiency PM induction machines

  Induction machines (three and single phase), synchronous machines with DC excitation, with PM-excitation, and with magnetically salient rotor and a linear Pm oscillatory motor are all investigated in terms of transients, electromagnetic FEM analysis and control principles. Case studies, numerical examples, and lots of discussion of FEM results for PMSM and IM are included throughout the book.

The optimal design is treated in detail using Hooke-Jeeves and GA algorithms with case comparison studies in dedicated chapters for IM and PMSM. Numerous computer simulation programs in MATLAB® and Simulink® are available online that illustrate performance characteristics present in the chapters, and the FEM and optimal design case studies (and codes) may be used as homework to facilitate a deeper understanding of fundamental issues.
