Detailed Solution
Download Solution PDF- The number of parallel paths in an 8 pole, simplex lap wound armature in DC generator is 8.
- Armature windings are mainly of two types – lap winding and wave winding
- Lap winding is the winding in which successive coils overlap each other. It is named “Lap” winding because it doubles or laps back with its succeeding coils.
- In this winding, the finishing end of one coil is connected to one commutator segment and the starting end of the next coil situated under the same pole and connected with the same commutator segment.
- Lap winding are of two types – Simplex Lap Winding & Duplex Lap Winding
- A winding in which the number of parallel paths between the brushes is equal to the number of poles is called simplex lap winding.
- A winding in which the number of parallel paths between the brushes is twice the number of poles is called duplex lap winding.
- Wave winding is the armature winding in which two coils are connected in series and follow each other on the surface of the armature like waves such that there are only two paths for the current flow irrespective of the number of poles in the circuit.
- In this winding number of parallel paths between the brushes is always 2.
