Like any other part of the motor, the winding can fail armature winding in which the coils are laid in two layers and follow each other on the surface of the armature in the form of waves with the coils being so connected in series that there are only two paths for the flow of current whatever the number of poles in the machine. Simplex wave windings. Duplex wave windings. Retrogressive wave windings. Progressive wave windings main advantage of wave winding is requirement of lesser amount of conductor and carbon brushes. This is because the number of parallel path in wave winding is always 2, therefore two carbon brushes are only required. A wave winding may be fitted with as many brushes as the number of poles
