Answer Posted / engineer aamir ali
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.
