Gianmario Pellegrino, Thomas M. Jahns, Nicola Bianchi, Wen L. Soong, Francesco Cupertino Rediscovery of Synchronous Reluctance and Ferrite Permanent Magnet Motors

Annotation

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.
