The Wave Winding

The wave winding is an alternative way to connect the rotor (armature) coils to the commutator segments. Fig. (1.6) shows a simple wave winding. In this simplex wave winding, every other rotor coil connects back to a commutator segment adjacent to the beginning of the first coil. Therefore, there are two coils in series between the adjacent commutator segments. Furthermore, since each pair of coils between adjacent segments has a side under each pole face, all output voltage are the sum of the effects of every pole, and there can be no voltage imbalances. wave windings, generators produce higher-voltage, low current outputs, since the number of coils in series between commutator segments permits a high voltage to be built up more easy than with lap windings.
