| Lap Winding | Wave Winding |
|---|---|
| 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. |
