From the fan motor in your PC to precision control of aircraft, electrical machines of all sizes, varieties, and levels of complexity permeate our world. Some are very simple, while others require exacting and application-specific design. Electrical Machine Analysis Using Finite Elements provides the tools necessary for the analysis and design of any type of electrical machine by integrating mathematical/numerical techniques with analytical and design methodologies.Building successively from simple to complex analyses, this book leads you step-by-step through the procedures and illustrates their implementation with examples of both traditional and innovative machines. Although the examples are of specific devices, they demonstrate how the procedures apply to any type of electrical machine, introducing a preliminary theory followed by various considerations for the unique circumstance. The author presents the mathematical background underlying the analysis, but emphasizes application of the techniques, common strategies, and obtained results. He also supplies codes for simple algorithms and reveals analytical methodologies that universally apply to any software program.With step-by-step coverage of the fundamentals and common procedures, Electrical Machine Analysis Using Finite Elements offers a superior analytical framework that allows you to adapt to any electrical machine, to any software platform, and to any specific requirements that you may encounter.

Reluctance motors induce non-permanent magnetic poles on the ferromagnetic rotor; the rotor does not have any windings and torque is generated through magnetic reluctance. Synchronous reluctance motors (SyRMs) have an equal number of stator and rotor poles. Reluctance motors can deliver high power density at low cost, so they are finding increasing application in the transport sector. Disadvantages include high torque ripple and the complexity of designing and controlling them. Advances in theory, computer design, and control electronics can overcome these issues.This hands-on reference covers the concept and design of synchronous reluctance motors. It conveys all key topics required to understand this technology. Chapters cover magnetic materials, geometry, modeling, design and analysis, optimization, production technology, fault-tolerance, experimental validation, and self-sensing-oriented optimization.Synchronous Reluctance Machines: Analysis, optimization and applications is ideal for researchers working on electrical machines and motors, particularly electric vehicles. The writers - experts from academia and industry - provide the reader with an excellent background and understanding of the core concepts involved in synchronous reluctance motors such that they can engage in their own R&D.The authors of this book are kindly donating all royalties to Operazione Mato Grosso.

This book offers an essential compendium on theanalysis and design of synchronous motors for variable-speed applications.Focusing on synchronous reluctance and ferrite permanent-magnet (PM)synchronous reluctance machines, it provides a broad perspective on three-phasemachines for variable speed applications, a field currently dominated byasynchronous machines and rare-earth PM synchronous machines. It also describessynchronous reluctance machines and PM machines without rare-earth materials,comparing them to state-of-the-art solutions. The book provides readers withextensive information on and finite element models of PM synchronous machines,including all relevant equations and with an emphasis on synchronous-reluctanceand PM-assisted synchronous-reluctance machines. It covers ferrite-assistedmachines, modeled as a subcase of PM-assistance, fractional slot combinationssolutions, and a quantitative, normalized comparison of torque capability withbenchmark PM machines. The book discusses a wealth of techniques foridentifying machine parameters, with an emphasis on self-commissioningalgorithms, and presents methods for automated machine design and optimization,including a software tool developed for this purpose. Addressing an importantgap in the field of PM-less and less-PM electrical machines, it is intended asa self-contained reference guide for both graduate students and professionalmachine designers, and as a useful text for university courses on automatedand/or optimized design of electrical machines and drives.
