Description du livre
This book offers an essential compendium on the
analysis 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-phase
machines for variable speed applications, a field currently dominated by
asynchronous machines and rare-earth PM synchronous machines. It also describes
synchronous reluctance machines and PM machines without rare-earth materials,
comparing them to state-of-the-art solutions. The book provides readers with
extensive information on and finite element models of PM synchronous machines,
including all relevant equations and with an emphasis on synchronous-reluctance
and PM-assisted synchronous-reluctance machines. It covers ferrite-assisted
machines, modeled as a subcase of PM-assistance, fractional slot combinations
solutions, and a quantitative, normalized comparison of torque capability with
benchmark PM machines. The book discusses a wealth of techniques for
identifying machine parameters, with an emphasis on self-commissioning
algorithms, and presents methods for automated machine design and optimization,
including a software tool developed for this purpose. Addressing an important
gap in the field of PM-less and less-PM electrical machines, it is intended as
a self-contained reference guide for both graduate students and professional
machine designers, and as a useful text for university courses on automated
and/or optimized design of electrical machines and drives.
