* Distributed Windings: In this configuration, each coil's turns are spread out over several slotsMMF plot of the 8-pole, 48 slot stator winding. A common setup is the lap winding or wave winding, where each slot typically contains coil sides from multiple coils作者：J Asama·2022·被引用次数：1—An axial flux (or axial gap) permanent magnet (PM) motor with48-slot/8-poledistributedwindinghas been developed for electric motorcycle applications.. For instance, in some 48 slot designs with a sufficient number of elements per slot, a lap winding might be implemented where each slot has one coil side, meaning the total number of coils equals the number of slots. The distribution factor calculation for lap windings becomes essential in these scenarios.Distribution factor calculation for lap windings
* Concentrated Windings: Here, coils are wound around a single tooth or a narrow group of slots.
