Fractional Slot Concentrated Windings : Design, Analysis, and Optimization

A consolidation of all known FSCW types and their optimization methods Fractional Slot Concentrated Windings provides an in-depth analysis of fractional slot concentrated windings (FSCWs), reviewing theoretical foundations, existing FSCWs including three-phase and multiphase windings and their optimization methods, benefits, challenges, and solutions associated with FSCWs. Numerous winding topologies for real-world applications in traction motors, aerospace systems, robotics, industrial drives, and renewable energy systems are also included. This book delves into detailed examinations of distinct winding groups and explores optimization techniques with dedicated chapters on specialized coil configurations. For each FSCW group, the main winding topologies and their associated winding layouts are explained. Written by a highly qualified author in the field, this book includes information on: Analytical approaches for the calculations of MMF characteristics and their winding factorsA specific FSCW configuration with unequal zones and asymmetric zone distributions, expanding the spectrum of standard concentrated winding topologiesUnique winding structures, such as the two-tooth coil-pitch design, alongside a review of star-delta combination concepts for FSCWsThe flux-barrier technique, including the implementation of flux barriers in both the stator yoke and stator teeth regionsNovel winding solutions for radial-flux and axial-flux machines Covering principles, performance, and optimization, Fractional Slot Concentrated Windings serves as a comprehensive guide for engineers, researchers, and practitioners working with FSCWs in the design and optimization of modern electrical machines.
