Among various electrical machine technologies, permanent magnet synchronous machines (PMSMs) are inherently more efficient and have high power/torque density due to permanent magnet excitation. To date, single three-phase electrical machines and drives have prevailed. However, multiphase electrical machines and drives have many advantages, such as excellent fault-tolerant capability, good power sharing capability, high torque/ power density, low torque ripple, additional degrees of freedom for control, reduced dc-link capacitor requirement, good modularity, and easy maintenance and repairing, etc. They are particularly attractive for applications requiring high reliability and high power, such as power generation, aerospace, electrified transportations including electric vehicles, aircrafts, trains, and ships, etc. Multi-threephase electrical machines, particularly dual three-phase electrical machines, have become more popular among multiphase electrical machines since mature threephase inverters and control techniques can be utilized. This book aims to provide a comprehensive reference on the principles, machine topologies, winding configurations, modelling and design optimization techniques, various modulation strategies and control methods including field oriented control, direct torque control, model predictive control, sensorless control, and fault-tolerant control, as well as current harmonic and torque ripple minimization techniques for multiphase PMSMs, with particular reference to dual threephase PMSMs. We have strived to highlight the global research achievements and many new techniques developed at the University of Sheffield. I would like to acknowledge the contributions from my PhD students and postdoctoral researchers at Sheffield who worked on multiphase and multi-three-phase PMSMs, including Dr Arwyn Thomas, Dr Khoa Dang Hoang, Dr Kai Wang, Dr Yuan Ren, Dr Yashan Hu, Dr Beomseok Lee, Dr Ali Almarhoon, Dr Peilin Xu, Dr Yanxin Li, Dr Xue Liu, Dr Jin Xu, Dr Javier Riedemann, Dr Tianyi Liu, Dr Dawei Liang, Dr Bo Shao, Dr Luocheng Yan, Dr Shensheng Wang, Dr Yang Chen, Mr Jialu He, and Mr Furkan Tokgoz. I also thank Mr Ian Parmenter for English proofreading. I dedicate my thanks to our sponsors, including the UK government, particularly the UK EPSRC Prosperity Partnership (“A New Partnership in Offshore Wind” under Grant No. EP/R004900/1), and our industrial partners, e.g. Siemens on wind power, Rolls-Royce on aerospace, CRRC on fast train propulsion, NEVC, Midea, Protean, Nissan, and Toyota on electric vehicles.
