what is the difference between concentrated winding and Distributed winding in motor?..

concentrated wdg means one phase wdg under one slot only.
in distributed wdg one slot accomodate two or three phase
wdg i.e. more than one.

what is the difference between concentrated winding and Distributed winding in motor?..

distributed winding is one in which the windings are
distributed along a number of slots. the major merit of
this is the heat dissipation is better.
whereas in concentrated winding, the windings are
concentrated only on one slot. here, since more number of
coils is in one slot, the heat produced is more.

what is the difference between concentrated winding and Distributed winding in motor?..

A winding with only one slot per pole per phase is called a
concentrated winding. In this type of winding, the e.m.f
generated/phase is equal to the arithmetic sum of the
individual coil e.m.f.s in that phase. However, if the
coils/phase are distributed over several slots in space,
this kind of winding is called distributed winding. The
e.m.f.s in this case are not in phase but are displaced from
each other by the slot angle. the e.m.f will be the phasor
sum of the coil e.m.f.s.

what is the difference between concentrated winding and Distributed winding in motor?..

Concentrated winding in 3 phase armature means that the value of distribution factor (kd in many references) be equal to 1. It means that the winding is concentrated along a pole.
In distributed winding the value of kd in the base winding (machine period) is below 1, which determines that the value of the induced EMF in one phase is less than the value of "induced EMF in one coil * number of coils series in one phase" .
With this definition the only winding in 3 phase anrmature which have concentrated winding is the machine having q=1 (q is the number of slot per pole per phase) .
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, then we can see that the kd will be lower than one for this machine (q=0.4).
These type of machines which has one slot pitch for the each coil of their winding are called "tooth wound machines" and not concentrated.

what is the difference between concentrated winding and Distributed winding in motor?..

concentrating winding means winding which is wounded at a single slot or place or position (say field pole) so that flux produced as a combination is more concentrated and also dissipation is high as heat loss due to both current through it and of adjascent winding heat and it is low power winding.where as distributed winding means winding is distributed along a number of slots and it is high power winding.
