High-speed Slotless Permanent Magnet Machines: modelling and design frameworks

This paper presents a design framework for high-speed slotless permanent magnet machines based on extended harmonic modeling (HM) technique to predict various electromagnetic properties and torque distribution. The developed models for generic design framework are able to evaluate slotless PM machines' topologies with a wide range of 3D slotless windings, (including those with skewing), and can be also used for future design optimization routines.
