Fractional-Slot Concentrated-Windings Synchronous Permanent Magnet Machines: Opportunities and Challenges
TLDR
This paper will cover the theory and design of FSCW synchronous PM machines, achieving high-power density, flux-weakening capability, comparison of single- versus double-layer windings, fault-tolerance rotor losses, parasitic effects, compared of interior versus surface PM machine, and various types of machines.Abstract:
Fractional-slot concentrated-winding (FSCW) synchronous permanent magnet (PM) machines have been gaining interest over the last few years. This is mainly due to the several advantages that this type of windings provides. These include high-power density, high efficiency, short end turns, high slot fill factor particularly when coupled with segmented stator structures, low cogging torque, flux-weakening capability, and fault tolerance. This paper is going to provide a thorough analysis of FSCW synchronous PM machines in terms of opportunities and challenges. This paper will cover the theory and design of FSCW synchronous PM machines, achieving high-power density, flux-weakening capability, comparison of single- versus double-layer windings, fault-tolerance rotor losses, parasitic effects, comparison of interior versus surface PM machines, and various types of machines. This paper will also provide a summary of the commercial applications that involve FSCW synchronous PM machines.read more

Performance of a Folded-Strip Toroidally Wound Induction Machine
TL;DR: It is shown that if the machine is axially restricted in length, the toroidally wound induction machine can have substantially shorter stator end windings than conventionally winding induction machines, and hence, it shows that a toroidal wound induction Machine can have lower losses and a higher efficiency.
