fractional slot winding 2 Concentrated winding theory A winding is called “concentrated” when the number of slots per pole per phase is fractional and strictly lower than one This  Fractional-slot-winding motors utilize a unique winding configuration that reduces cogging torque compared to motors with integer slot windings   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
