Two types of windings mostly employed for the armature of DC Machines are known as;
1.Lap Winding2.Wave Winding
The difference between the two is merely due to the different arrangement of the end connections at the front or commutator end of armature.
In a LAP WINDING, the number of parallel paths (a) is always equal to the number of poles (p) and also equal to the number of brushes.
In a WAVE WINDING, the number of parallel paths (a) is always two and there may be two or more brush points.
