|Lap winding is suitable for low voltage and high current generator.
||Wave winding is suitable for high voltage but a low current generator.
|No. of parallel path the armature= mp(where m is a multiplicity of winding and P = no.poles)
||No. of parallel paths = 2m
|For same emf generation, lap winding requires large no. of conductors.
||For same emf generation, wave winding requires less no. of conductors.
|So cost is more.
||so cost is less.
|More utilization of space in armature slot
||Less utilization of space in armature slot
|Commutator pitch Yc=+ 1.
||commutator pitch Yc where YA is an average pitch.
|Back and front Pitches are odd of the opposite.
||Both pitch YB and YF are odd and off same sign.
