What is the number of parallel paths of a 4 pole duplex lap winding?

Lap winding

Lap winding is a type of armature winding in which the coil terminals are connected in such a way that the number of parallel paths is equal to the number of poles (for simplex winding) or a multiple of it (for multiplex windings).

This type of winding is commonly used in high-current, low-voltage applications like large DC generators and motors.

The number of parallel paths in a lap winding is given by:

A = P × m

where, A = Number of parallel paths

P = Number of poles

m = Multiplicity of winding (1 for simplex, 2 for duplex, 3 for triplex, etc.)

Calculation

Given, P = 4 

m = 2

The number of parallel paths is given by:

A = 4 × 2

A = 8
