What method of armature winding is used for high current applications?

Lap winding is a method commonly used for high current applications due to its design features that allow for lower armature resistance and better performance in handling larger currents. In this type of winding, the coil sides overlap, which helps to reduce the magnetic leakage and enhances the generator's or motor's torque. The overlapping nature enables it to handle the larger current loads expected in high power applications, while also providing a favorable distribution of the winding around the armature.

This winding technique also facilitates easier connections to the commutator, making it advantageous for applications where robust current conduction is necessary. As a result, lap winding is widely utilized in large DC motors and generators, where the operational demands require efficient performance under high current conditions.
