Theory and design of fractional-slot multilayer windings

Six Phase Permanent Magnet Machine with Fractional Slot fractional slot winding The paper presents a new algorithmic method of designing fractional-slot windings for AC machines of the double and single layer type The method allows to pg 999 slot Slots Not Divis- ible by 3 Since the winding pitch and the magnitude of D in the D - series depend upon the value of spp in all fractional
