This paper deals with fractional-slot multilayer windings They are becoming attractive since they allow to reduce the harmonic content of the windings

fractional slot winding Such a winding is referred to as a fractional slot winding because the conductors of a single phase occupy a fractional number of slots, for example, slots

This paper describes in detail six-phase fractional slot windings with a winding step of two slots It discusses possible combinations of slots
