Fractional-Slot Concentrated-Windings Synchronous Permanent Magnet Machines: Opportunities and Challenges

  title={Fractional-Slot Concentrated-Windings Synchronous Permanent Magnet Machines: Opportunities and Challenges},
  author={Ayman M. El-Refaie},
  journal={IEEE Transactions on Industrial Electronics},
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… CONTINUE READING
