Book Description
This book investigates the utilization of harmonics in the permanent magnet (PM) or rotor shape to improve the torque density of PM brushless AC machines including three-phase inner rotor and outer rotor machines, five-phase machines, dual three-phase machines, linear machines, by means of analytical, finite element analyses, and as well as experimental validation. The torque density can be improved while the torque ripple remains low in PM shaping utilizing the 3rd harmonic. In this book, the analytical expression of output torque is derived for PM machines with rotor shape using the 3rd harmonic, and then the optimal 3rd harmonic for maximizing torque is analytically obtained. The book compares the PM shape in surface-mounted PM (SPM) machines and the rotor lamination shape in interior PM (IPM) machines utilizing the 3rd harmonic, and it becomes clear that their shaping methods and amount of torque improvement are different. In a five-phase PM machine, the 3rd harmonic can be utilized in both the current waveform and PM shapes to further improve the output torque. For the dual three-phase SPM machines without deteriorating the torque more than 30% when the optimal 3rd harmonic into both the current and PM shape are injected. The harmonics in airgap flux density have significant influence on the cogging torque, stator iron flux distribution, and radial force between the rotor and stator. These effects has been investigated as well in this book.

Book Description
The third edition of Induction Machines Handbook comprises two volumes, Induction Machines Handbook: Steady State Modeling and Performance and Induction Machines Handbook: Transients, Control Principles, Design and Testing. The promise of renewable (hydro and wind) energy via cage-rotor and doubly fed variable speed generators e-transport propulsion, i-home appliances makes this third edition state of the art tool, conceived with numerous case studies, timely for both Academia and Industry. The first volume offers a thorough treatment of steady state modeling and performance of induction machines, the most used electric motors (generators) in rather constant or variable speed drives for even lower energy consumption and higher productivity in basically all industries, from home appliances, through robotics to e-transport and wind energy conversion. The second volume presents a practical up to date treatment of intricate issues with induction machine (IM) required for design and testing both in rather constant and variable speed (with power electronics) drives. It contains ready to use in industrial design and testing knowledge with numerous case studies to facilitate thorough assimilation of new knowledge.
