Difference between Lap winding and Wave winding

Lap winding and Wave winding: In this article we will discuss about Lap winding and Wave winding difference.

Lap Winding:

Lap winding may also be called as parallel or multiple winding system.
Lap winding consists of starting coil and end coil, In this winding the end coil is connected to the commutator and starting coil is connected to the same pole.
In this winding system, there is an overlap on each other sides of coils.
In this type of winding, it may contain single or multi windings are provided.
If there is a single winding system is used then the connections of parallel paths are in same with poles present init.
If there is a multi-winding system is used then the connections of parallel paths are double to the poles present in it.

Wave winding system:

The system which carries current in opposite direction is called wave winding.
This type of system is a series winding.
Wave winding is mostly used in high voltage machines.
If the current in coil must flow in one direction then the connection should be in series.
