Advantages of integral slot winding
Initially a simple case will be assumed where SPP is an integral number; such winding is referred to as integral-slot winding. For illustrative purposes, let m = 2 which means 12 slots per pole pair for a 3-phase armature. Slot angle is 360°/12 = 30°. Further let the coil-pitch be full six slots. Figure 6.2(a) shows the 12 slots numbered from left to right; six slots are under the influence of one pole with a particular direction of emfs in coil-sides and the remaining six slots are under ...

what is the difference between concentrated winding and Then there is machines which has the winding with one slot pitch (q=0.4), but illegally said to have concentrated winding but actually the winding is distributed with kd=0.9659 and kp=0.9659 and therefore kw=kd*kp=0.933. (Kp is pitch factor) . The value of winding factor (kw) could be determined with star diagram of winding, and pitch factor too,... What are the advantages of distributed winding in rotating Mar 24, 2017 · slot under a single pole. this armature winding is known as distributed winding. Although distributed armature winding of alternator, reduces emf but still it very much usable due to following reason. It also reduces harmonic emf and so wave form is improved. It also diminishes armature reaction.

Harmonic Analysis and Comparison of the Back EMFs of Four ... - NTNU Fractional-slot windings have advantage of reducing slot harmonics comparing to integral-slot windings . And for high pole machines where high slot number ... Armature Windings in Alternator & Types of Armature Windings
When m is integer then the basic unit under a pole pair N and S keeps on repeating n the winding for any number of pole pairs. In fractional slot winding, in order to construct a basic unit, the ratio S/3P is further reduced to irreducible fraction by cancelling out the highest common factor from S and P.
